QUICKSTART OPERATING INSTRUCTIONS

This manual contains detailed operating instructions for all aspects of the DFX ow instrument. The following condensed instructions are provided to assist the operator in getting the instrument started up and running as quickly as possible. This pertains to basic operation of the clamp-on transducer only. If specic instrument features, a hazardous area installation or an alternate transducer style are to be used; or if the installer is unfamiliar with this type of instrument, refer to the appropriate section in the manual for complete details.

1  TRANSDUCER LOCATION

1) Determine the appropriate mounting location for the transducers by referring to Figure 1.1. Pipe must be lled with liquid to ensure proper operation.

2  PIPE PREPARATION AND TRANSDUCER MOUNTING

1) The piping surface, where the transducers are to be mounted, needs to be clean and dry. Remove loose scale, rust and paint to ensure satisfactory acoustical bonds.

2) Connect the mounting straps around the pipe. Leave the strap loose enough to slip the transducers underneath.

3) Apply a liberal amount of couplant grease onto the transducer faces.

4) Place each transducer under the mounting strap, 180° apart on the pipe. Ensure that the transducer cables are facing the same direction on the downstream side of the ow. See Figure 1.2.

5) Route the transducer cable back to the DFX monitor, avoiding conduits that contain high voltage AC supply wires.

3  TRANSDUCER CONNECTIONS

1) Mount DFX monitor within the length of the transducer cables. While transducer cable extension is not generally recommended, if additional transducer cable length is required, utilize cable and connectors of the correct type and impedance. In many cases, especially if a splice my be exposed to water or other liquids, it may be more eective to replace the entire cable. Transducers use RG59 ,75 ohm coaxial cable or Twinax (Belden #9463) or (Belden # 9463DB) 78 Ohm two conductor cable.

2) Route the transducer cables through the center conduit hole in the bottom of the DFX enclosure and connect to terminal block J4. The terminal blocks are a removable and can be disconnected to simplify wiring access. A wiring diagram is located on the inner door for reference.

4  STARTUP

INITIAL SETTINGS AND POWER UP

1) Verify that the DFX power supply jumper settings are properly congured for the power supply that will be utilized. A wiring and jumper selection diagram is located on the inner door for reference.

NOTE: Power supply selection is specied during order placement and appropriate jumpers are placed at the factory. If power is changed from AC to DC or vice versa, the fuse requirement will change. Fuse ratings are listed on the transmitter’s door.

2) Route power connections through the conduit hole farthest to the left and in the DFX enclosure. Then connect power to the J2 terminal block. See Figure 3.2.

3) Apply power.

4) On initial power-up, the DFX conducts a series of self-diagnostic tests and buering operations that take approximately 30 seconds.

5) Enter pipe internal diameter (Pipe ID), measuring units and output conguration.

PART 1  INTRODUCTION

GENERAL

The DFX ultrasonic ow meter is designed to measure volumetric ow of solids-bearing or aerated liquid within closed conduit. Transducers are available as non-contacting (DT9) or insertion probe (DP7) types. DT9 non-contacting transducers are strapped to the outside of a pipe and are suitable for most installations where the pipe material supports the transmission of ultrasound. Some pipe materials, such as concrete pressure pipe and some plastic lined pipes do not allow ultrasound to penetrate to the liquid inside. For these applications, the DP7 insertion probe will be needed.

The ow meter operates by transmitting an ultrasonic sound from its transmitting transducer through the pipe wall or from the probe tip into the moving liquid. The sound will be reected by useful sonic reectors are moving within the sound transmission path, sound waves will be reected at a frequency shifted (Doppler frequency) from the transmitted frequency. The shift in frequency will be directly related to the speed of the moving particle or bubble. This shift in frequency is interpreted by the instrument and converted to various user dened measuring units.

What makes a good Doppler reector? The four criteria are:

suspended within the liquid and recorded by the receiving transducer. If the sonic reectors

t The scattering material must have a sonic impedance (sound speed dierence) at least 10% dierent

from the uid.

t There must be some particles large enough to cause longitudinal reection – particles larger than 35

micron.

t For a given pipe size, the longitudinal reection must have sucient energy to overcome the

Rayleigh (energy wasting) scattering caused by smaller particles.

t The reecting material must travel at the same velocity as the uid for good accuracy.

APPLICATION VERSATILITY

The DFX ow meter can be successfully applied on a wide range of metering applications. The easy to program transmitter allows the standard product to be used on pipe sizes ranging from 1” - 120” (25 mm

- 3050 mm) pipe I.D. With the small pipe transducer option, the pipe size range is 0.25” - 1” (6 mm - 25 mm). A variety of liquid applications can be accommodated:

sewage river water plant euent mining slurries sludge others

Because the transducers are non-contacting and have no moving parts, the ow meter is not aected by system pressure, fouling or wear. Standard transducers are rated to a pipe surface temperature of 250 °F (121 °C). Optional high temperature transducers are rated to operate to a pipe surface temperature of 400 °F (204 °C).

06-DPP-UM-00147 02/12 9

USER SAFETY

The DFX employs modular construction and provides electrical safety for the operator. The enclosure is constructed from rugged polycarbonate plastic with UV inhibitors. The enclosure does not contain any conductive materials that can become energized while the door is closed. The keypad is also manufactured from polycarbonate and is designed for outdoor use. The AC power transformer provides 4,000 Volts of isolation from the power supply mains. The display face contains voltages no greater than 24 VDC. Output modules are optically isolated from external power supplies and provide a great degree of immunity to ground loops.

CAUTION: If the DFX is used in a manner not specied by the manufacturer, the protection provided by the equipment may be impaired.

DATA INTEGRITY

The DFX product retains all user conguration data and totalizer accumulations in non-volatile FLASH memory indenitely.

PART 2  TRANSDUCER INSTALLATION

UNPACKING

After unpacking, it is recommended to save the shipping carton and packing materials in case the instrument is stored or re-shipped. Inspect the equipment and carton for damage. If there is evidence of shipping damage, notify the carrier immediately.

MOUNTING LOCATIONS

The transducers that are utilized by the DFX contain piezoelectric crystals for transmitting and receiving ultrasonic sound energy through the pipe wall in the case of the series DT9 transducer and from the probe tip of the series DP7. Placement of the ultrasonic transducer is the most critical step in achieving an accurate and reliable ow reading. All ow meters of this type rely on a full-pipe of uid that is owing symmetrically (evenly) in the pipe. Flow in partially lled pipes and immediately downstream of elbows, valves and pumps is unstable and will lead to unstable readings and non-linearity.

Figure 2.1 illustrates ve possible pipe congurations and recommends installation only in locations where it can be guaranteed that the pipe will be lled at all times when ow measurements are required. The two locations illustrated in the top two drawings may allow the meter to operate, but it is unlikely that stable and accurate ow readings will be realized over a very large range of ow. Since products like the DFX have software algorithms that assume a full-pipe of liquid, partially-lled pipes can lead to very large ow measurement errors and should be avoided.

FIGURE 2.1  PIPE CONFIGURATIONS AND INSTALLATION RECOMMENDATIONS

The DFX system will provide repeatable measurements on piping systems that do not meet these

requirements, but the accuracy may be inuenced to various degrees.

14 06-DPP-UM-00147 02/12

PIPE PREPARATION

Before the transducer heads are mounted to the pipe surface, an area slightly larger than the at surface of the transducer face must be prepared. If pipe insulation is present, it must be peeled back to expose the pipe surface. Typical preparation involves wire brush removal of loose paint, rust, scale or dirt. Paint, if bonded well to the pipe surface, does not need to be removed. The bumps present on ductile iron pipe do not need to be removed. Thoroughly dry the mounting surfaces so that the couplant grease will properly bond to the surface.

NOTE: Small pits in the piping surface typically do not signicantly impact ultrasonic transmission or signal reception.

COUPLANT

To assure an acoustically conductive path between the transducer face and the prepared piping surface, a coupling compound is employed. Clamp-on ultrasonic meters will not operate without coupling compound mounted between the pipe wall and the transducer face. Enclosed with the DFX system is a tube of coupling compound that is adequate for general purpose applications. Dynasonics prefers siliconebased valve grease or RTV (Room Temperature Vulcanizing) products or grease for Doppler installations as they operate over a very wide temperature range. In some installations, such as automotive, silicone is not permitted. Alternate petroleum-based products can be utilized, but verify that the grease is rated not to ow at the maximum surface temperature anticipated on the pipe.

In general, utilize the following couplants with these transducers:

DT90, DT91, DT94, DT95 Dow 732 or Dow 111 (or equivalent) DT92, DT93, DT96, DT97 Krytox® LVP DP7 Not applicable

DT9 CLAMPON TRANSDUCER MOUNTING

Clamp-on transducers should be mounted on the pipe 180° apart and facing each other on the pipe, with the cables on the downstream side of the transducers. If the pipe is horizontal, the preferred mounting orientation is 3 and 9 o’clock, with 12 o’clock being the top of the pipe. See Figure 2.3. Orientation on vertical pipes does not matter.

FIGURE 2.3  TRANSDUCER PLACEMENT

PROCEDURE:

1) Large pipe installations utilize stainless steel straps to secure the transducers to the outside of the pipe. The DFX system is shipped with four 36” (900 mm) straps, which are suitable for pipes up to 39” (1000 mm) diameter. Select the proper number of transducer straps to allow a complete strap to go around the circumference of the pipe. If a pipe is larger than 39” (1000 mm), it is recommended that a single strap/buckle arrangement be utilized to reduce the number of strap connections. See Table 2.1. The straps can be connected together to make a continuous length. Small pipe installations do not utilize straps, but use an integral clamping mechanism built into the transducer.

Pipe Size Straps Required

1” to 9” (25 mm to 225 mm) 1 10” to 19” (250 mm to 480 mm) 2 20” to 29” (500 mm to 740 mm) 3 30” to 39” (760 mm to 1000 mm) 4

TABLE 2.1  STRAPS REQUIRED VS. PIPE SIZE

2) Wrap the strap around the pipe in the area where the transducers are to be mounted. Leave the strap loose enough to allow the transducers to be placed underneath. If multiple straps are being used, it can be benecial to wrap electrical tape around all but one strap connection to secure the strap worm screws in place.

3) Spread an even layer of coupling compound, approximately ⁄” (3 mm) thick, to the prepared transducer mounting areas of the pipe.

16 06-DPP-UM-00147 02/12

4) Spread an even layer of coupling compound, approximately ⁄” (3 mm) thick, to the at face of the two transducers.

5) Place each transducer under the strap with the at face – amber plastic window – positioned towards the pipe. The notch on the back of the transducer will provide a mounting surface for the strap. The transducer cables must be facing in the same direction and downstream of the transducers for proper operation.

NOTE: Large pipes may require two people for this procedure.

6) Tighten the strap strong enough to hold the transducers in place, but not so tight that all of the couplant squeezes out of the gap between the transducer face and pipe. Ensure that the transducers are squarely aligned on the pipe and 180° apart. If RTV is utilized, avoid moving the transducers during the curing time – typically 24 hours – as bubbles may form between the transducer and pipe that can reduce ultrasonic signal transmission to unsatisfactory levels.

7) Route the transducer cables back to the area where the transmitter will be mounted, avoiding high voltage cable trays and conduits. While transducer cable extension is not generally recommended, if additional transducer cable length is required, utilize cable and connectors of the correct type and impedance. In many cases, especially if a splice my be exposed to water or other liquids, it may be more eective to replace the entire cable. Transducers use RG59, 75 ohm coaxial cable or Twinax (Belden #9463) or (Belden # 9463DB) 78 Ohm two conductor cable.

8) If the transducers are to be permanently mounted using Dow 732, the RTV must be completely cured before proceeding to Instrument Start-up. Ensure that no relative motion between the transducer and pipe occurs during the 24 hour curing process. If Dow 111 grease was used for temporary operation of the DFX system, proceed with the Instrument Start-up procedures.

DP7 PROBE TRANSDUCER MOUNTING

The DP7 insertion transducer that is utilized by the DFX contains piezoelectric crystals for transmitting and receiving ultrasonic sound energy. The black Ultem® plastic tip of the DP7 contains these crystals, which are designed to be inserted just into the path of the owing liquid.

Select a transducer mounting location that will be completely lled with liquid when ow measurements are to be made (See Figure 2.1) and with adequate straight runs (without disturbances) of pipe, both upstream and downstream, to achieve stable and accurate readings. Examples of minimum upstream and downstream requirements are included in Figure 2.2. Note that if adequate straight piping cannot be provided, the DFX system will operate repeatably, but will probably not achieve ideal accuracy.

When installing the DP7 transducer in a horizontal pipe, the preferred orientation is at least 20 degrees from the top or bottom of the pipe – See Figure 2.4. Ensure that the mounting location allows for adequate clearance to install and retract the probe fully from the pipe.

The following instructions also cover hot tapping, installations where it is required to install or remove the transducer probe without shutting down the process pressure. If the product is being installed without an isolation valve, ignore the steps that pertain to its installation. Figure 2.5 illustrates an exploded view of an isolation valve assembly and names the various components.

If the Bronze Hot Tap Kit (p.n. D030-1006-001) or Stainless Steel Hot Tap Kit (p.n. D030-1006-002) accessory kits were ordered with the DP7 probe, a hot tapped installation can be completed. The kits include an isolation valve assembly and are de-

4) Complete welding. A water tight, 0.25” minimum weld bead is recommended.

5) Install the close nipple (supplied with assembly) into the weld coupling. Use appropriate pipe sealants.

6) Install the isolating ball valve on the close nipple. Verify that the valve is in fully open position.

7) Install drill bit and adapter into the pressure drilling machine. Then attach the machine to the isolation valve.

8) Drill through the pipe wall in accordance with the instructions supplied with the drilling machine.

9) Withdraw the drill bit through the isolating valve. Close the valve and remove the drilling machine. Check for leakage at valve and connections.

10) Place pipe sealant on the 1½” NPT threads of the insertion tting assembly. Screw the assembly into the isolation valve and tighten with a 2½” pump wrench.

PROBE INSERTION

Before inserting the DP7 probe into the piping system, it is necessary to calculate the probe insertion depth that will place the measuring electrodes at the proper position in the pipe. In order to complete this calculation, some knowledge of the piping system must be known. Refer to the paragraphs that follow and Figure 2.6 for information regarding this process. The variables required are:

t The overall probe length. t Pipe internal diameter (I.D.). t Pipe wall thickness. t The length of the valve stack. t Amount of straight pipe diameters in the system.

Using this information and referring to Figure 2.6, proper insertion depth can be determined.

Measurement A — The typical depth that the DP7 probe tip is inserted into the piping system is ⁄ (12.5%) of the pipe internal diameter. Measurement B — Pipe wall thickness. This information can be obtained from standard pipe wall charts See the Appendix of this manual) or ideally can be measured using an ultrasonic wall thickness gauge. Measurement C — Measure the distance that is going to be taken up by the pipe tap, nipple, full-ow ball valve and the insertion tting. DP7 probes utilize 1½” NPT hardware and the insertion tting is approximately 2.5” in height. Measurement E — This is the overall length of the probe measured from the black measurement tip to the top ange on the probe. Measurement D — This is the length of DP7 probe that will be protruding from the insertion tting after it is inserted to the proper depth in the uid stream.

1) Lubricate the O-rings located within the DP7 probe seal tting so that the seals are not damaged during probe insertion.

2) Run the lower jam nuts down to a point that approximates the nal insertion position or at least far enough to allow insertion into the insertion tting. Using the threaded rods as a guide, position the probe in the insertion tting. Continue to insert the probe as far into the isolation assembly as possible. The probe tip will come in contact with the closed “ball” in the isolation valve.

CAUTION: Do Not Force the Probe Tip Against the “Ball”, as damage to the probe tip may result.

3) Replace the upper jam nuts (2 on each rod) and the cotter pins. The nuts should be run down to the top side of the retaining collar and the cotter pins replaced. Orient the probe in the direction of ow as indicated by the FLOW direction arrow located on the top of the probe ange. See Fig- ure 2.8. Lock the probe in position with the enclosed Allen wrench.

CAUTION: The nuts on both ends of the retaining rods must always be in place as a safety measure to prevent possible probe blow out. Inserting cotter pins is a further safety measure.

4) Slowly open the isolation valve. When the valve is fully open, use the proper size wrench on the insertion nuts, alternately tightening each nut about two complete turns to avoid uneven seal loading.

PROBE CABLES

Before inserting the probe into the pipe, the sensor cables should be routed to the transmitter location. Verify that the supplied cable length is sucient to meet the installation requirements. While transducer cable extension is not generally recommended, if additional transducer cable length is required, utilize cable and connectors of the correct type and impedance. In many cases, especially if a splice my be exposed to water or other liquids, it may be more eective to replace the entire cable. Transducers use RG59 ,75 ohm coaxial cable or Twinax (Belden #9463) or (Belden # 9463DB) 78 Ohm two conductor cable.

CAUTION: The probe cables are designed to carry low level signals that are developed by the sensor. Care should be taken in routing the cables. Avoid running cables near sources of high voltage or EMI/RFI. Also avoid routing the cables in cable tray congurations, unless the trays are specically used for other low voltage, low level signal cables.

CAUTION: The internal DP7 probe wiring is epoxy encapsulated to seal it from moisture. The DP7 probe is provided with two coaxial cables to shield the low level signals and must be continuous to the DP7 probe transmitter. Excess wire may be cuto or simply coiled near the DFX instrument.

PROBE RETRACTION PROCEDURE

1) Retract the probe by loosening the upper jam nuts counterclockwise as viewed from the top of the probe using the proper size wrench. If the pipe is under pressure, the nuts must be turned alternately about two turns at a time to prevent binding as a result of non-equal seal loading. In many cases, the line pressure will cause the probe to retract. Should the probe bind, use the retraction nuts on the lower side of the probe ange to assist in the probe retraction. Continue this procedure until the probe is fully retracted into the isolation valve.

06-DPP-UM-00147 02/12 21

CAUTION: Do not run the drive nuts o the rods until the isolation valve is fully closed.

2) After the probe is retracted past the “ball” in the isolation valve, the isolation valve may be closed to isolate the probe from the line and the probe can be removed entirely.

CAUTION: If the insertion probe is not above the “ball” of the isolation valve, the valve cannot be closed. If the valve will not close smoothly, the body or tip of the probe is most likely not above the “ball”. Attempting to force the valve into the closed position may result in damage to the probe.

PART 3  TRANSMITTER INSTALLATION

UNPACKING

MOUNTING LOCATION

The enclosure should be mounted in an area that is convenient for servicing, calibration and for observation of the LCD readout.

1) Locate the transmitter within the length of transducer cable that was supplied with the DFX system. If this is not possible, it is recommended that the cable be exchanged for one that is of proper length. While transducer cable extension is not generally recommended, if additional transducer cable length is required, utilize cable and connectors of the correct type and impedance. In many cases, especially if a splice my be exposed to water or other liquids, it may be more eective to replace the entire cable. Transducers use RG59 ,75 ohm coaxial cable or Twinax (Belden #9463) or (Belden # 9463DB) 78 Ohm two conductor cable.

2) Mount the DFX transmitter in a location that is:

t Where little vibration exists t Protected from falling corrosive uids t Within ambient temperature limits -40 to +185 °F (-40 to +85 °C) t Out of direct sunlight. Direct sunlight may increase transmitter temperature to above the maxi-

mum limit

3) Mounting: Refer to Figure 3.1 for enclosure and mounting dimension details. Ensure that enough room is available to allow for door swing, maintenance and conduit entrances. Secure the enclosure to a at surface with four appropriate fasteners.

4) Conduit holes: Conduit hubs should be used where cables enter the enclosure. Holes not used for cable entry should be sealed with plugs.

NOTE: Use NEMA 4 (IP-65) rated ttings/plugs to maintain the watertight integrity of the enclosure. Generally, the left conduit hole (viewed from front) is used for line power, the center conduit hole for transducer connections and the right hole is utilized for ISO-MOD I/O wiring.

5) If additional holes are required, drill the appropriate size hole in the enclosure’s bottom. Use extreme care not to run the drill bit into the wiring or circuit cards.

MULTIPLE METER INSTALLATIONS

The DFX ow meter contains a provision for synchronizing multiple DFX ow meters together. Synchronization is required when more than one DFX ow meter is mounted on a common pipe or header system. If meters are not synchronized, a phenomena called “cross-talk” can occur between meters, which can lead to erroneous readings or no readings at all. Cross-talk results from the small dierences in transmitted frequency generated from two or more dierent ultrasonic ow meters. By synchronizing the transmitted ultrasonic energy, cross-talk caused by dierences in transmitted frequency is eliminated.

The DFX synchronization circuit is designed to interconnect up to four DFX ow meters over a cable length of 100 feet (30 meters). Utilize 20-22 AWG twisted-pair shielded interconnection wire for this purpose. See Figure 3.7.

TO SYNCHRONIZE MULTIPLE METERS:

1) Remove power from the DFX ow meters.

2) Daisy-chain connect the EXTernal SYNChronization and GND terminal blocks together between the meters to be synchronized, utilizing the twisted-pair cable described previously. The terminal block is located on the circuit board that is mounted on the door of the DFX monitor. See Wiring Diagram Figure 3.4, the decal on the inner door of the DFX monitor or schematic.

3) At a single point, connect the shield drain wire from the interconnection cable to earth ground.

4) Congure the SYNC SELECT jumpers on the DFX ow meters. One DFX should be congured for INT and the remaining units congured for EXT (see below).

5) Apply power to the DFX system.

The DFX utilizes ISO-MODs for input and output functions. ISO-MODs are epoxy encapsulated electronic input/output modules that are simple to install and replace in the eld. See Figure 3.9. All modules are 2,500 V optically isolated from DFX power and earth grounds. This eliminates the potential for ground loops and reduces the chance of severe damage in the event of an electrical surge.

Three ISO-MOD options are available, including: 4-20 mA, dual-relay and rate pulse. The DFX supports any two ISO-MOD input/output modules. All modules are eld congurable by utilizing the keyboard interface. Field wiring connections to ISO-MODs are quick and easy using removable wiring terminals. Conguration and connection of the various ISO-MODs are described on the following pages.

ISO MODULE REPLACEMENT

To remove an ISO-MOD, remove the two machine screws that secure the module in place and pull the module straight out of the enclosure. A 10-pin connection is on the bottom of the module that mates with the circuit board underneath. Installation of a module is simply the reverse operation of removal. 4-20 mA modules will require calibration parameters to be entered if the module is replaced. See Part 4 of this manual for instructions on entry of calibration parameters.

INTERNAL POWER CONFIGURATION

Ensure that jumpers are in place at JP1 and JP2 on the module – reference Figure 3.10B. In this congu- ration, the 4-20 mA output is driven from a +24 VDC source located within the DFX ow meter. The 24 VDC source is isolated from DC ground and earth ground connections within the DFX instrument. The module can accommodate loop loads up to 800 Ohms in this conguration.

NOTE: The +24 internal supply, if congured to power the 4-20 mA output, shares a common ground with another ISO-MOD (if installed). If another module is connected to earth ground, a ground loop may occur. The solution to this problem is to congure the 4-20 mA module for external power and utilize an external isolated supply to power the 4-20 mA loop.

EXTERNAL POWER CONFIGURATION

Remove the two jumpers located at JP1 and JP2 on the module – reference Figure 3.10C. In this con- guration the 4-20 mA module requires power from an external DC power supply. The voltage of the external power source must be sucient to power the module and drive the loop load. The loop loss attributed to the ISO-MOD is 7 VDC, so the minimum voltage required to power a loop can be calculated using the following formula:

Loop voltage (min) = (loop load Ohms × 0.02) + 7

CONTROL RELAY OUTPUT MODULE

Two independent SPDT (single-pole, double-throw, Form C) relays are contained in this module. The relay operations are user congured via the front panel to act in either a ow rate alarm, error alarm or totalizing pulse. The relays are rated for 200 VAC maximum and have a current rating of 0.5 A resistive load (175 VDC @ 0.25 A resistive). It is highly recommended that a secondary relay be utilized whenever the Control Relay ISO-MOD is used to control inductive loads such as solenoids and motors.

Typical relay connections are illustrated in Figure 3.11A. The reed relays located within the relay module can interface directly with small pilot lights, PLCs, electronic counters and SCADA systems.

Figure 3.11B describes the connection of an external power relay to the Relay ISO-MOD. It is recommended that external power relays are utilized whenever the load to be switched exceeds the switch rating of the reed relays, or if the load is inductive in nature.

The Rate Pulse Output Module is utilized to transmit information to external counters and PID systems via a frequency output that is proportional to system ow rate. The frequency output range of the Rate Pulse Module is 0-2,500 Hz. This module has two types of outputs: one simulates the output of the coil of a turbine ow meter and the other is an open-collector type that does not source voltage at its output. Both outputs may be connected simultaneously.

The turbine meter output creates a 500 mV peak-to-peak saw-tooth waveform that is not referenced to ground. This output can be run to electronic monitors that are compatible with variable reluctance outputs from coils, such as those found in turbine and paddle-wheel ow meters. The input impedance of the receiving device should not be smaller than 2,000 Ohms.

The standard pulse output does not output a voltage, but acts as an “open-collector” output requiring an external power source and pull-up resistor. See Figure 3.12. The MOSFET in the Rate Pulse Module can support loads of 100 V @ 1 A. Resistor selection is based on the input impedance of the receiving device. Select a resistor that is a maximum of 10% of the input impedance of the receiving device, but does not exceed 10k Ohms.

FLUID SPECIFIC GRAVITY

SP GRAV -- Fluid Specic Gravity (Value) Unitless Value

Allows adjustments to be made to the specic gravity (density relative to water) of the liquid.

If Pounds (LBS) or Kilograms (KGS) is selected for either the RATE UNT or the TOTL UNT, a specic gravity must be entered for the correct mass ow to be calculated. A list of uids and their associated specic gravities is located in the Appendix of this manual.

NOTE: Specic Gravity only appears when LBS or KGS are selected in either Rate Unit or Total Unit

LOW FLOW CUTOFF

F C-OFF -- Low Flow Cut-o (Value) Unitless Value

A Low Flow Cut-o entry is provided to allow very low ow rates (that can be present when pumps are o and valves are closed) to be displayed as Zero ow. The value entered is in actual rate units.

SCALE FACTOR

SCALE F -- Scale Factor (Value)

0.500 to 5.000

This function can be used to make the DFX system agree with a dierent of reference ow meter, or to compensate for an installation where there is inadequate straight pipe to obtain a laminar ow prole, by applying a correction factor/multiplier to the readings and outputs. A factory calibrated system should be set to 1.000. The range of settings for this entry is 0.5000 to 5.000. The following example describes using the SCALE F entry.

The DFX meter is indicating a ow rate that is 4% higher than another ow meter located in the same pipe line. To make the DFX indicate the same ow rate as the other meter, enter a SCALE F of 0.960, to lower the readings by 4%.

SYSTEM DAMPING

DAMPING -- System Damping (Value) Relative Percent Entry: 0-99%

Flow Filter Damping establishes a maximum adaptive lter value. Under stable ow conditions (ow varies less than 10% of reading), this adaptive lter will increase the number of successive ow readings that are averaged together up to this maximum value. If ow changes outside of the 10% window, the Flow Filter adapts by decreasing and allows the meter to react faster. Increasing this value tends to provide smoother steady-state ow readings and outputs.

ISO MOD 420 mA

ISO-MOD -- 4-20 mA FLOW 4MA FLOW 20MA CAL 4MA CAL 20MA 4-20 TEST

Congured via jumper selections for either a passive (current sinking) or active (current sourcing) transmission mode (see Part 3 for details), the 4-20 mA Output Module interfaces with virtually all recording and logging systems by transmitting an analog current signal that is proportional to system ow rate. Independent 4 mA and 20 mA span settings are established in memory using the ow measuring range entries. These entries can be set anywhere in the measuring range of the instrument. Output resolution of the module is 12-bits (4096) discrete points) and the module can drive up to 800 Ohms of lead with its internal 24 V isolated power source.

420 MA SPAN

The FLOW 4MA and FLOW 20MA entries are used to set the span of the 4-20 mA analog output. These entries are volumetric rate units that are equal to the volumetric units congured as Engineering Rate Units and Engineering Units Rate Interval.

For example, to span the 4-20 mA output from 0 GPM to +100 GPM, with 12 mA being 50 GPM, set the FLOW 4MA and FLOW 20MA values as follows:

FLOW 4MA = 0.0 FLOW 20MA = 100.0

42 06-DPP-UM-00147 02/12

420MA CALIBRATION

The 4-20 mA ISO-MOD is factory calibrated and should not require adjustment unless it is replaced.

NOTE: The CAL 4MA and CAL 20MA entries should not be used in an attempt to set the 4-20 mA range. Utilize FLOW 4MA and FLOW 20MA, detailed above, for this purpose.

CAL 4MA CHOICE

The 4-20CAL? entry allows ne adjustments to be made to the “zero” and span of the 4-20 mA output. Select YES to access adjustment. To adjust the 4 mA output, a milliammeter or reliable reference must be connected to the 4-20 mA output.

PROCEDURE:

1) Disconnect one side of the current loop and connect the milliammeter in series (disconnect either wire at the terminals labeled +/- on the ISO-MOD 4-20 mA module) see Figure 4.2.

2) Using the arrow keys, increase the numerical value to increase the current in the loop to 4 mA. Decrease the value to decrease the current in the loop to 4 mA. Typical values range between 40-80 counts.

3) Re-connect the 4-20 mA output circuitry as required.

420TEST  420 MA OUTPUT TEST

Allows a simulated value to be output from the 4-20 mA output. By incriminating this value, the 4-20 mA output will transmit the indicated current value.

ISOMOD RATE PULSE

FLOW 0HZ (Value) FL MAXHZ (Value) RATE TST

The Rate Pulse Output Module is utilized to transmit information to external counters and PID systems via a frequency output that is proportional to system ow rate. Independent Zero and Span settings are established in memory using the ow measuring range entries. Output resolution of the module is 12bits (4096 discrete points) and the maximum output frequency setting is 2,500 Hz. The module has two output modes, turbine meter simulation and “open collector”. The turbine meter simulation sources a non-ground referenced saw-tooth waveform with a maximum peak amplitude of approximately 500 mV p-p. The open-collector output utilizes a 0.21 Ohm MOSFET output that is rated to operate at 100 V and 1 A maximum. If the open-collector output type is utilized, an external voltage source and limit resistor must be present. See Part 1 of this manual for connection information.

RATE PULSE SPAN

The FLOW 0HZ and FL MAXHZ entries are used to set the span of the 0-2.5 kHz frequency output. These entries are volumetric rate units that are equal to the volumetric units congured as Engineering Rate Units and Engineering Units Rate Interval.

For example, to span the 0-2.5 kHz output from 0 GPM to +100 GPM, with 1.25 kHz being 50 GPM, set the FLOW 0HZ and FL MAXHZ values as follows:

FLOW 0HZ = 0 FL MAXHZ = 100.0

RATE PULSE TEST

RATE TST  RATE PULSE OUTPUT TEST

Allows a simulated value to be output from the rate pulse output. By incrementing this value, the rate pulse output will transmit the indicated frequency in terms of percentage of the maximum output frequency.

For example, if the maximum output frequency is 2500 Hz, increment the displayed value to 50 to output a test frequency of 1250 Hz.

ERRORS

Two independent SPDT (single-pole, double-throw, Form C) relays are contained in this module. The relay operations are user congured via the keypad to act in either a total pulse output, ow rate alarm or error alarm mode. The relays are rated for 200 VAC maximum and a have current rating of 0.5 A resistive load (175 VDC @ 0.25 A resistive). It is highly recommended that a secondary relay be utilized whenever the Control Relay ISO-MOD is used to control inductive loads such as solenoids and motors.

TOTALIZER RELAY

TOTAL mode congures the relay to output a 50 mSec pulse (contact changeover) each time the display totalizer increments.

FLOW RATE RELAY

Flow Rate Relay conguration permits relay changeover at two separate ow rates allowing operation with an adjustable switch deadband. Figure 4.3 illustrates how the setting of the two set points inuences Rate Alarm operation.

A single-point ow rate alarm would place the ON> setting slightly higher than the OFF< setting – allowing a switch deadband to be established. If a deadband is not established, switch chatter (rapid switching) may result if the ow rate is very close to the switch point.

46 06-DPP-UM-00147 02/12

When the unit is powered up, there is a delay before the unit begins transmitting sound into the pipe. During this time, the signal strength is measured and a base signal level is obtained. Typically this is a value of about 20. The unit measures ow by measuring the Doppler frequency shift. The frequency shift is approximately 70 Hz per foot per second. For every foot per second increase in velocity, the signal strength should increase by 1. The unit automatically adjusts the gain and selects the proper hardware lter for the measured velocity. The control can be observed when the DISPLAY mode is set to DIAG. See Figure 4.4.

RUN

FIGURE 4.4  DIAGNOSTIC DISPLAY

When NORMAL is selected, the unit will automatically control the gain and front end hardware lter for optimum measurement of the Doppler signal.

Select HIGH for applications where the unit reads ow rates consistently, but much lower than the actual ow rate. This may be required when sound is not getting through the pipe as well. Selecting HIGH will cause the unit to look for the signal strength to increase by 2 for every foot per second increase in ow rate. Basically, the gain is doubled, but still automatically controlled.

For applications where the ow is constant, but you may need to tune the unit to lter out extraneous noise, select the MANUAL mode. Typically, this would only be required at very low ow rates. When MANUAL mode is selected, the GAIN POT and FILTER settings are manually set. Automatic control is disabled.

GAIN CONTROL

GAIN POT  DIGITAL GAIN POT

0-64

Using the arrow keys, increase or decrease the numerical value to set the signal gain level. Typically, optimum ow measurement is made when this value is between 10 and 50. Use the lowest value that provides an accurate and stable ow reading. This adjustment must be made in conjunction with the FILTER setting, and may be an iterative process.

HARDWARE FILTER

FILTER  HARDWARE FILTER SELECTION

Select the hardware lter with a cuto frequency that is above the Doppler shift frequency to be measured. The Doppler shift frequency is found by multiplying the ow velocity (in FPS) by 80.

For example, if the ow velocity is 4 FPS then the cuto frequency is 4 × 80 or 320 Hz. The lter with the next highest frequency would be 350 Hz.

This value is established at the factory during calibration. If a new set of transducers or insertion probe is connected , the new correction factor should be entered. The correction factor values can be found on transducers or probes labels.

48 06-DPP-UM-00147 02/12

LINEARIZATION

LINEAR  ENTRY OF LINEARIZATION DATA

The Linearization feature allows for correction of ow readings caused by non-linear ow measurement. This typically occurs when there is insucient straight piping before or after the location where the transducers are mounted.

Up to 10 linearization points may be entered. The microprocessor will perform a linear interpolation between data points entered in the linearization table and apply the associated correction factor to the measured ow rate.

Start by entering the number of linearization points to be entered at the NUM PTS prompt. If a value of 00 is entered, linearization is disabled.

The unit will then prompt for FREQ 1 to be entered. Enter the measured frequency corresponding to the ow rate for the rst point. This can be obtained by running actual ow with the DISPLAY mode set to DIAG and reading the measured frequency, or by calculating the frequency if the ow rate in feet per second is known using the following formulas:

DT9 Clamp-On Transducer: Freq = Velocity (FPS) × 80 Hz DP7 Insertion Probe Transducer: Freq = Velocity (FPS) × 80 Hz

The unit will then prompt for COEFF 1 to be entered. This is the value that the measured ow rate will be multiplied by at this point. Enter the coecient or correction factor to be applied. The value entered must be between 0.5 and 1.5.

Repeat this procedure for all of the linearization points. When all of the points have been entered, the unit will return to the NUM PTS prompt. Press the Menu key to return to the main menu LINEAR prompt. Then using the arrow keys, move to the next setup parameter.

PART 5  STARTUP AND TROUBLESHOOTING

DFX STARTUP REQUIREMENTS

NOTE: The DFX ow meter system requires a full pipe of owing liquid before a successful startup evaluation can be completed. Do not attempt to make adjustments or make Manual conguration changes until a full pipe of owing liquid is veried.

NOTE: If an RTV sealant was utilized to couple the transducers to the pipe, the sealant must fully cure before power is applied to the instrument. Most RTVs require 24 hours to cure satisfactorily. It is very important that the transducers are not moved during the curing process – air bubbles can form between the transducer and the pipe wall and inuence performance. If silicone grease was utilized as a couplant, the curing time is not required.

PROCEDURE:

1) Verify that the DT9 or DP7 transducer has been properly installed and wired – See Part 2.

2) Verify that the DFX power supply jumper settings are properly congured for the power supply that will be utilized – See Part 3.

3) Verify that the DFX is properly programmed – See Part 4.

4) Apply power.

5) On initial power-up, the DFX microprocessor conducts a series of self-diagnostic tests, base-line measurements and begins to buer liquid velocity data. During this start-up, approximately 30 seconds, ow rate readings and outputs will be inhibited.

6) After the start-up routine has completed running, the meter will begin to display ow rate and/or total as congured.

7) If an ERROR appears on the DFX lower display, pleaser refer to the following Troubleshooting pages for resolution.

3. More than one DFX installed on the piping system – See Part 3: Multiple Unit Installation

4. Insucient particles over 35 microns – inject air upstream of the transducers

5. Too many particles that are smaller than 35 micron – ultrasonic meters likely will not operate

6. Transducer failure – unplug transducer cable from J4, measure capacitance between blue/clear or red/black Receive and Transmit. Verify that the capacitance on each set is approximately 2 nF (nano Farads) – and within 0.02 nF of each other

5. Verify that the data collection system is accepting the pulses from the DFX – connect to Turbine out or OUT/IN as required

1. When run in AUTO mode, the DFX utilizes a series of lters that optimize readings for a particular ow range. The ow meter will take several seconds to adjust to a step change in ow. To make the ow meter respond quickly to changes in ow, decrease DAMPING, place the meter into MANUAL AGC and lock the FILTER at NONE.
