PART 1 - INTRODUCTION

General

The MagProbe is a point-velocity measuring device used primarily
for measuring electrically conductive liquids, such as water and
water-based liquids, in closed piping systems. The unit operates
utilizing Faraday’s principle of magnetic conduction, whereby a
moving conductor (the liquid) has a voltage imposed on it that is
directly proportional to two variables—the strength of a local
magnetic field and the velocity of the moving conductor.

Imposed voltage  Magnetic field X Fluid velocity

If the strength of the magnetic field is held constant, then the
magnitude of the voltage will be proportional to the velocity of the
moving conductor. The equation then simplifies to Imposed voltage
 Fluid velocity. Most modern magnetic meters, including the MFX,
apply tri-stated, alternating polarity DC pulses to an integral
electromagnet. See Figure 1.3. Voltage measurements are made
with the magnet off, to measure ambient background noise, and
then with the magnet on
in both polarities. The
magnitude difference in
voltage measured is
proportional to flow. Once
fluid velocity is measured,
then various volumetric
flow measurements can
be obtained if the pipe
internal diameter (I.D.) is
known.

Point-velocity flow meters measure the fluid velocity at a specified
depth into the fluid stream, typically  of the pipe I.D., which has
been proven to be the nominal velocity point when symmetrical flow
profiles are present. This assumption requires the probe to be
certain numbers of pipe diameter downstream of any piping
condition (elbows, valves, thermo-wells, tees, etc.) that can cause
flow abnormalities. Typically, a minimum of 15 pipe diameters of
straight pipe is required to develop a symmetrical flow profile.
Systems where symmetrical flow profiles are not present can still be
measured accurately, but flow profiling must be performed to
determine proper probe insertion depth. A diagram of the MagProbe
tip is illustrated in Figure 1.4.

PART 1 - INTRODUCTION

The MFX MagProbe flow meter can be successfully applied on a
wide range of metering applications. The simple to program
transmitter allows the standard product to be used on pipe sizes
ranging from 4 - 120 inch (100 - 3048 mm) pipe. A variety of liquid
applications can be accommodated: potable water, chemicals, raw
sewage, reclaimed water, cooling water, river water, plant effluent,
etc. The MFX product will not operate on fluids with very high
impedance such as DI water, distilled water, petroleum-based
liquids or glycol-based liquids.

Transmitter
Installation

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.

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

1. Locate the transmitter within the length of MagProbe cable that
was supplied with the MFX system. If this is not possible, replace
the entire length of interconnect cable with Belden
9536, Dynasonics part number D005-1003-003 or equivalent. Do
not splice the cable as shield integrity will be compromised and
poor performance can result.

2. Mount the MFX transmitter in a location that is:

i Where little vibration exists.

i Protected from falling corrosive fluids.

i Within ambient temperature limits -40 to +185°F (-40 to +85°C)

i Out of direct sunlight. Direct sunlight may increase temperatures

within the transmitter to above maximum limit.

3. Mounting: Refer to Figure 1.5 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 flat 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 4X (IP66) rated fittings/plugs to maintain the
water tight 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 or side. Use extreme care not to run the
drill bit into the wiring or circuits cards.

PART 1 - IS O-MO D

General

The MFX utilizes ISO-MODs for input and output functions. ISO­MODs are epoxy encapsulated electronic input/output modules that
are simple to install and replace in the field. See Figure 1.10. All
modules are 2,500 V optically isolated from MFX 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.

Figure 1.10

Two ISO-MOD I/O Modules Installed

Six ISO-MOD options are available, including: 4-20 mA, dual-relay,
rate pulse, RS232C, RS485, and 200k point data logger. The MFX
supports any of the six ISO-MOD input/output modules. All modules
are field configurable by utilizing the keyboard or ULTRALINK™
interface. Field wiring connections to ISO-MODs are quick and easy
using removable plug-in terminals. Configuration and connection of
the various ISO-MODs are described on the following pages.

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 3 of this manual for instructions on entry of
calibration parameters.

Rev. 01/11 -1.16- MFX

PART 1 - IS O-MO D

4-20 mA Output

The 4-20 mA Output Module interfaces with most recording and
logging systems by transmitting an analog current signal that is
proportional to system flow rate. The 4-20 mA ISO-MOD may be
configured via jumper selections for either an internally powered
mode (current sourcing) Figure 1.11A or externally powered mode
(current sinking) Figure 1.11B.

Internal Power Configuration: Ensure that jumpers are in place at
JP1 and JP2 on the module. See Figure 1.11A. In this
configuration the 4-20 mA output is driven from a +24 Vdc source
located within the MFX flow meter. The 24 Vdc source is isolated
from DC ground and earth ground connections within the MFX
instrument. The module can accommodate loop loads up to 800
Ohms in this configuration.

External Power Configuration: Remove the two jumpers located at
JP1 and JP2 on the module. See Figure 1.7B. In this
configuration the 4-20 mA module requires power from an external
DC power supply. The voltage of the external power source must be
sufficient 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 x 0.02) + 7

Control Relay

Two independent SPDT (single-pole, double-throw) Form C relays
are contained in this module. The relay operations are user
configured via software to act in either a flow rate alarm, signal
strength alarm or totalizer/batching mode. 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 1.12A. The reed
relays located within the relay module can interface directly with
small pilot lights, PLCs, electronic counters and SCADA systems.

Figure 1.12B 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.

Rate Pulse

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 flow 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 flow 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
flow 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 pull­up resistor. See Figure 1.13. The MOSFET in the Rate Pulse
Module can support loads of 100 V @ 1A. 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 do not exceed 10k Ohms.

RS232C

The RS232C Module will interface with the serial communication
ports of PCs, PLCs and SCADA systems that are used to monitor
flow rate information in piping systems. A proprietary digital
communications protocol is used for this communication. An
explanation of the command structure is detailed in the Appendix of
this manual. Flow rate, total, signal strength and temperature (if so
equipped) can be monitored over the digital communications module.
The RS232C Module may also be used to form a hardwire
connection to a PC that is running the ULTRALINK™ software
utility. Baud rates up to 19.2k are supported. Figure 1.14 illustrates
typical connections.

PART 1 - IS O-MO D

RS485

The RS485 Module allows up to 128 MFX systems to be placed on
a single three-wire cable bus. All meters are assigned a unique one
byte serial number that allows all meters on the cable network to be
independently accessed. A proprietary digital communications
protocol is used for this communication. An explanation of the
command structure is detailed in the Appendix of this manual. Flow
rate, total, signal strength and temperature (if so equipped) can be
monitored over the digital communications bus. Baud rates up to
9600 and cable lengths to 5,000 feet (1,500 meters) are supported
without repeaters or “end of line” resistors. ULTRALINK™ is also
compatible with a multiple MFX network, allowing individual meters
to be accessed, programmed, diagnosed and calibrated.

To interconnect meters, utilize three-wire shielded cable such as
Belden

®

9939 or equal. In noisy environments the shield should be
connected on one end to a good earth ground connection. An
RS232 to RS485 scond, such as B&B electronics p/n 485SD9TB
(illustrated in Figure 1.15) is required to interconnect the RS485
network to a communication port on a PC. If more than 128 meters
must be monitored, an additional scond and communication port is
required.

Data Logger

The 200,000 event data logger/electronic stripchart recorder can be
configured to match most user applications. The logger stores time­stamped, high resolution (16-bit) data at user selected intervals
ranging from 1 to 1,000 seconds. Configuration of and data retrieval
from the logger are detailed in Sections 3 and 4 of this manual.

The module can be carried in a shirt pocket back to the office and
plugged into a PC serial port via the module’s integral DB-9
connector. See Figure 1.16. This eliminates the requirement to
carry a computer to the flow meter site. The data in the logger can
also be accessed without removing the module from the flow meter.
Open the door of the flow meter and interconnect the 9-pin cable
between the data logger and the PC serial communications port.
The logger is capable of storing up to 200,000 measurements. The
measurements are broken into 16 blocks or pages with a maximum
number of data points per block of 30,000.

If each block(page) is filled to the maximum, 6-2/3 blocks would be
used:

If all 16 blocks are to be used, each block could hold 12,500 data
points:

NOTE: The data logger is not accessible using the MFX’s infrared
adapter. Communications between the data logger and computer
must be accomplished using a directly connected RS232C or
RS485 connection.

The DMP insertion probe that is utilized by the MFX flow meter
system contains an electromagnet, electrodes and amplification
circuitry. Three electrodes, two measurement and one ground, are
located in the black Ultem
to be inserted to the average fluid velocity point within a pipe. Not all
liquid within a pipe is flowing at a uniform fluid velocity, but a long
straight run of pipe, full of flowing liquid, contains a predictable liquid
velocity profile. By selecting proper upstream and downstream
lengths of straight pipe from the probe installation point and by
making precise insertion depths into the pipe, very accurate and
reliable volumetric flow rates and totals can be obtained.

Select a probe mounting location 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 Table 2.1.
Note that if adequate straight plumbing cannot be provided, the
MFX system will operate repeatably

When installing the DMP probe in a
horizontal pipe, the preferred
orientation is between 1 and 5 o’clock
on the pipe—assuming 12 o’clock as

Hot-tapped installation will require the installation of either a welded
pipe coupling or installation of a pipe saddle. The ball valve and
close nipple can be purchased as a kit from Dynasonics or can be
procured at most hydraulic or plumbing supply shops. The two
critical factors that must be considered with the components are
pressure rating and internal sizes. The DMP2 through DMP6 1-½"
MagProbes are designed to operate with pipe pressures up to 700
psi (48 Bar). Verify that the internal port of the opened valve is at
least 1-½ inches (38 mm) to permit free passage of the probe
without interference. Attempts to force a MagProbe through an
opening smaller that stated will damage the probe tip and void the
warranty.

Component
Assembly

These instructions call for the use of a drilling machine designed for
drilling holes in pipes that are under pressure (for example, Muller
Co., Decatur, Illinois manufactures products for this purpose).

Procedures are as follows:

1. Verify that the line pressure within the pipe is within the rated

limits of the pressure drilling machine, welded coupling or pipe
saddle, valve and MagProbe to be used.

2. Grind off paint or other coatings from the pipe in the area where

the DMP MagProbe Assembly is to be installed. Recommended
minimum straight pipe lengths for best accuracy are 10
diameters upstream and 5 downstream. See Table 2.1.

3. Tack weld a 1-½" NPT female weld-coupling to the pipe or

install a pipe saddle according to the suppliers instructions. The

coupling or saddle must be aligned perpendicular to the
pipe axis and square to its plane.

4. Complete welding. A watertight, 0.25" minimum weld bead is

recommended.

5. Install the close nipple 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.

Step D -
Probe Insertion
Distances

PROBE INSERTION

Before inserting the MagProbe 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 2.3
for information regarding this process. The variables required are:

x The overall probe length
x Pipe internal diameter
x Pipe wall thickness (including liners)
x The length of the valve stack
x Amount of straight pipe diameters in the system

Using this information and referring to Figure 2.3 proper insertion
depth can be determined.

Measurement A — the typical depth that the MagProbe tip is
inserted into the piping system is  (12.5%) of the pipe internal
diameter. Assume  of the pipe internal diameter unless a system
piping configuration does not have
straight pipe in the installation area.

at least 15 pipe diameters of

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. If the pipe is lined, include the liner thickness in
this measurement.

Measurement C — Measure the distance that is going to be taken
up by the pipe tap, nipple, full-flow ball valve and the insertion fitting.

NOTE: DMP1 through DMP6 probes utilize 1-½" NPT hardware.
The insertion fitting for the DMP1 through DMP6 probes is
approximately 2.5 inches long once completely torqued into
position.

Measurement E — This is the overall length of the probe measured
from the black measurement tip to the top flange on the probe.

Measurement D — This is the length of MagProbe that will be
protruding from the insertion fitting after it is inserted to the proper
depth in the fluid stream.

Cable Routing

PROBE CABLE

Before inserting the MagProbe into the pipe, the sensor cables
should be routed to the transmitter location. Locate the transmitter
within the length of MagProbe cable that was supplied with the MFX
system. If this is not possible, replace the entire length of
interconnect cable with Belden
number D005-1003-003 or equivalent. Do not splice the cable as
shield integrity will be compromised and poor performance can
result. Cable lengths up to 1000 feet (300 meters) can be utilized.

NOTE!

Rev. 01/11 -2.7- MFX

CAUTION: Both power and digital signals are carried through the
MagProbe cable. These signals are robust, but care should be
taken in routing the cables. Avoid running cables near sources of
high voltage equipment or sources of extreme electrical noise—high
EMI/RFI. Also avoid routing the cables in cable tray configurations,
unless the trays are specifically used for other low voltage, low level,
signal cables.

Attach a wire of 12 AWG or larger between the #10-32 ground lug
on the insertion fitting and earth ground.

MagProbe
Insertion DMP2
through DMP6

MAGPROBE INSERTION DMP2 through DMP6

1. Apply sealant to the 1-½" NPT threads of the insertion fitting

assembly. Screw the assembly into the isolation valve and
tighten with a 2-½" pump wrench. Final orientation of the two
threaded rods on the MagProbe insertion fitting should be
approximately perpendicular to the pipe’s axis.

2. Run the lower Jam Nuts down to a point that approximates the

final insertion position or at least far enough to allow insertion of
the MagProbe into the insertion Fitting. Using the threaded rods
as a guide and with the flow direction arrow pointing in the
correct direction, position the MagProbe in the insertion fitting.
Continue to insert the MagProbe as far into the isolation
assembly as possible. The MagProbe tip will come in contact
with the closed “ball” in the isolation valve.

CAUTION: Do Not Force the MagProbe Tip Against the “Ball”, as
damage to the MagProbe 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 MagProbe in the
direction of flow as indicated on by the FLOW direction arrow
located on the top of the MagProbe amplifier enclosure. See

Figure 2.6.

Figure 2.6

Flow Direction

CAUTION: The nuts on both ends of the retaining rods must

always be in place as a safety measure to prevent possible
MagProbe blow out. Inserting cotter pins is a further safety
measure.

Retracting DMP2
through DMP6
Probes

4. Slowly open the isolation valve. When the valve is fully open,

use a 9/16" wrench on the insertion nuts, alternately tightening
each nut about two complete turns to avoid uneven seal
loading—two 9/16" ratcheting wrenches can expedite this
process. Repeat until the length of probe remaining above the
seal fitting equals the “D” length calculated in step D.

NOTE: For some low pressure/low temperature [less than 30 psi (2
Bar) and less than 100 °F (38 °C)], the MagProbe may be pushed in
by hand to decrease the insertion time. Dynasonics also offers
insertion cranking tools for these probes.

PROBE RETRACTION PROCEDURE

1. Retract the MagProbe by loosening the Upper Jam Nuts

counterclockwise—as viewed from the top of the MagProbe—
using a 9/16" 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—two 9/16"
ratcheting wrenches can expedite this process. In many cases,
the line pressure will cause the MagProbe to retract. Should the
MagProbe bind or if system pressure is very low, use the
retraction nuts on the lower side of the MagProbe flange to
assist in the MagProbe retraction. Continue this procedure until
the MagProbe is fully retracted into the insertion fitting.

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

2. After the MagProbe is retracted past the “ball” in the isolation

valve, the Isolation Valve may be closed to isolate the MagProbe
from the line and the MagProbe can be removed entirely.

CAUTION: If the probe tip 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 MagProbe is most likely not above
the “ball”. Attempting to force the valve into the closed position may
result in damage to the probe.

Module interfaces with virtually all recording and logging systems by
transmitting an analog current signal that is proportional to system
flow rate. Independent 4 mA and 20 mA span settings are
established in software using the Flow Measuring Range entries.
These entries can be set anywhere in the –30 to +30 FPS (-9 to +9
MPS) 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 load with its internal 24V isolated power source.

The FL 4MA and FL 20MA entries are used to set the span of the 4

If the Totalizer Exponent is set to E2 (100) and the Relay

If the Totalizer Exponent is set to E0 (1) and the Relay Multiplier

totalizer increments.

Flow Rate Relay configuration permits relay changeover at two
separate flow rates allowing operation with an adjustable switch
deadband. Figure 3.1 illustrates how the setting of the two set
points influences rate alarm operation.

A single-point flow 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 flow rate is very close to the switch point.

When a relay is set to ERROR mode, the relay will activate when
any error occurs in the flow meter that has caused the meter to stop

The MFX flow meter has been calibrated at the Dynasonics factory;
this calibration procedure includes calibration of “zero” flow. Field
calibration of “zero” is typically not required and other
troubleshooting methods should typically be reviewed to ensure that
the flow meter “zero” requires recalibration.

To zero the meter:

1. The pipe must be full of liquid.

2. Flow must be absolute zero—verify by closing a valve securely.

Allow time for any settling to occur.

3. Press ENTER, use the arrow keys to make the display read

YES.

Setting Zero on a
Flowing Pipe

Calibrating Zero on a Flowing Pipe

ULTRALINK™ provides a means to calibrate “zero” flow on a pipe
where the flow in the pipe cannot be shut off or blocked. To achieve
optimum results, the flow in the pipe must be steady during the
period when the calibration is performed. The procedure will take
several minutes. If the flow is not steady and a zero calibration is
required, it is best to remove the MagProbe sensor from the piping
system, place it into a container of water and perform the zero as
described in Section 3 of this manual.

To perform a zero calibration on a pipe with flowing liquid:

1. Press the Calibration button on the ULTRALINK™ main Data

Display. At Page 1 of 3, press the Next> button. See Figure

4.10.

the signal-to-noise ratio (flow meter data quality). The two lines
represent the voltage measurement across the electrodes with the
magnet biased with forward polarity and the other line with the
magnet biased with negative polarity. The separation between the
lines increases with flow velocity and as a line reaches the top or

05h Return Flow Data upon request: The data byte instructs the MFX processor to return

the flow data specified in the data byte. Flow data is sent once. No bbc is returned.

Data Information to be returned
10h Return velocity [:] [S] [+xx.xx] [\n]
11h Return flow rate [:] [F] [+xxxx.xx] [\n]
12h Return totallizer [:] [T] [+xxxxxx] [\n]
13h Return last conductivity [:] Y] [xxxx] [\n]

11h Preset Non-Volatile Data: This command, followed by 82 bytes of hex data will preset

the MFX programming registers to match the incoming data. The data structure is listed

later as NVD.

[;] [11h] [data] [data]......................[bbc] [\n]

15h Return Non-Volatile Data: this command will be cause the MFX to respond with

the data contained in the programming registers. The data structure is listed later as

NVD.

bbc generation: the bbc byte is generated by summing without overflow all characters in the transmis-

sion prior to the bbc byte excluding the [:] The bbc byte is then subtracted from ffh and
added to 01h. The incoming bbc byte is compared to the calculated bbc.

NVD structure: The non-volatile data is contained in a data structure as listed below: Care must be

taken when presetting the NVD registers as there is no error checking involved in preset­ting of these values. If improper data is supplied, the MFX may no longer function prop­erly, or may cease to function completely.
