QUICK-START OPERATING INSTRUCTIONS

MagProbe
Location

Top of Pipe

This manual contains detailed operating instructions for all aspects
of the MFX 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 only. If specific instrument features 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. SELECT THE MAGPROBE LOCATION

A. In general, select a mounting location on the piping system

with a minimum of 10 pipe diameters (10 X the pipe inside
diameter) of straight pipe upstream and 5 straight diameters
downstream. See Table 2.1 for additional configurations.

B. When the probe is installed on a horizontal pipe, the pre-

ferred orientation for the probe is between 1 and 5 o’clock
as shown in Figure 1.1. Ensure that the probe is installed
square and centered on the pipe.

2. HOT TAP CONFIGURATION

A. Verify that all components being permanently installed or

used during the installation procedure are rated for opera­tion at the greatest system pressure anticipated.

Figure 1.1

B. Mount the pipe saddle or weld fitting at the location deter-

mined in step 1. Install the close nipple and ball valve. Drill
a hole in the pipe that is at least 1/8” [3 mm] larger than the
MagProbe tip. Close the ball valve.

C. Install the MagProbe insertion fitting.

3. INSERT THE MAGPROBE INTO THE PIPE

A. To obtain greatest accuracy, the measuring tip of the Mag-

Probe must be inserted a proper distance into the pipe. For
long, straight runs of pipe, this is 12.5% of the pipe internal
diameter.

B. Before inserting the MagProbe into the insertion fitting, it is

best to make all of the necessary measurements on the
probe and installation fittings and place a insertion depth
mark on the probe.

C. Measure the full length of the probe (E), calculate 12.5% of

the pipe I.D. (A), obtain the pipe wall thickness (B) and
measure the distance between the outer pipe wall and the

General

PART 1 - INTRODUCTION

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 α 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 α
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 1/8 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

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.

Installation

After unpacking, it is recommended to save the shipping carton
and packing materials in case the instrument is stored or re­shipped. 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
part number 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:

♦ Where little vibration exists.

♦ Protected from falling corrosive fluids.

♦ Within ambient temperature limits -40 to 185°F [-40 to 85°C]

♦ Out of direct sunlight. Direct sunlight may increase tempera-

tures 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.

terminals on the MagProbe module. Observe proper wire colors
and shield connections. See Figure 1.6 or the Wiring Diagram
located on the inner door of the transmitter.

1. NOTE: The MagProbe cable carries low level signals. 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 part number
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.

Connect line power to the screw terminals marked L1, L2 and Earth
in the transmitter. See Figure 1.7 and Figure 1.8. Utilize the con­duit hole on the left side of the enclosure for this purpose. Use wir­ing practices that conform to local codes (National Electric Code
Hand book in the USA). The Earth ground terminal grounds the
instrument, which is mandatory for safe operation and optimum flow
meter performance.

CAUTION: Any other wiring method may be unsafe or cause im­proper operation of the instrument.

PART 1 - ISO-MOD

General

The TFXD 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 TFXD 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.

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.

Figure 1.10

Two ISO-MOD I/

O Modules

Installed

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. 2/2008 -1.16- MFX

PART 1 - ISO-MOD

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 saw­tooth 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
pull-up 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 - ISO-MOD

RS458

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
time-stamped, 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.

Startup

Note: The MFX flow meter system requires a full pipe of liq­uid before a successful startup can be completed. Do not at-

tempt to make adjustments or change configurations until a full
pipe is verified.

Procedure:

1. Verify that all wiring is properly connected and routed as de-

scribed in Part 1 of this manual.

2. Verify that the MagProbe sensor is properly mounted as de-

scribed in Part 2 of this manual.

3. Apply power. The display of a MFXD2 will display a software

version number and then all of the segments will illuminate in
succession. The meter will then enter run mode.

4. Verify that the following parameters have been entered into the

MFX Flow Meter in the BASIC MENU (See Section 3 of this
manual):

• UNITS—either ENGLISH or METRIC

• K-FACTOR (as it appears on the MagProbe sensor)

• PIPE Outside Diameter

• PIPE Wall Thickness

• PIPE Liner Thickness

• RATE unit selected

• RATE interval selected

5. Once these parameters have been entered and saved, the flow

meter will begin to measure and display flow rate. Section 3 of
this manual describes in greater detail the configuration and
programming of the MFX instrument.

Step A -
Mounting

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

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® plastic tip of the probe and are
designed 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

Step B - Hot
Tapped
Installation

The installation instructions cover Hot-Tapped installations
(installations where it is required to install or remove the Mag­probe 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 2.2 illustrates an
exploded view of an isolation valve assembly and names the
various components.
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 1-1/2” 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 1-1/2 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 1½" 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 water tight, 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.

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

• The overall probe length

• Pipe internal diameter

• Pipe wall thickness (including liners)

• The length of the valve stack

• 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 1/8 (12.5%) of the pipe internal di­ameter. Assume 1/8 of the pipe internal diameter unless a system
piping configuration does not have at least 15 pipe diameters of
straight pipe in the installation area.

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 1-1/2” 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 part number 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. Cable lengths up to 1000 feet [300 meters] can be utilized.

IMPORTANT
NOTE!

Rev. 2/2008 -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.

MAGPROBE INSERTION DMP2 through DMP6

1. Apply sealant to the 1-1/2” NPT threads of the insertion fitting

assembly. Screw the assembly into the isolation valve and
tighten with a 2-1/2” 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

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.

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

use a 9/16” wrench on the insertion nuts, alternately tightening

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".

DAMP PER establishes a maximum adaptive filter value. Under

stable flow conditions (flow that varies less than ±5%) this adaptive
filter will increase the number of successive flow readings that are
averaged together up to this maximum value. If flow changes
outside of the ±5% window, the Flow Filter adapts by decreasing
and allows the meter to react faster. A minimum filter setting is
established with the MIN DAMP setting described below. DAMP

PER is usually set to a value that is equal to or greater than MIN
DAMP. Increasing this value tends to provide smoother steady-

state flow readings and outputs.

In installations where very turbulent or erratic flow is encountered,

increasing the MIN DAMP setting can increase display and output
stability by forcing more averaging of flow readings. This filter is

Configured via jumper selections into either a passive or active
transmission mode (See Section 2 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 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
4-20 mA analog output. These entries are volumetric rate units
that are equal to the volumetric units configured as Engineering
Rate Units and Engineering Units Time Interval entered on page

3.10. These entries may be entered anywhere in the flow

measurement range of the instrument (velocity range of –30 to
+30 FPS [-9 to +9 MPS]).

NOTE: The Minimum Rate may be set anywhere in the flow
measurement range of –30 to +30 FPS [-9 to +9 MPS]). For
example: If bi-directional flow needs to be logged, set the MIN
RATE at a negative value.

For example, to span the 4-20mA output from –100 GPM to +100
GPM, with 12mA being 0 GPM, set the FL 4MA and FL 20MA

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

The CAL4MA entry allows fine adjustments to be made to the
“zero” of the 4-20mA output. To adjust the 4mA output, an
ammeter or reliable reference connection to the 4-20mA output
must be present.

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

Procedure:

1. Disconnect one side of the current loop and connect the

ammeter in series (disconnect either wire at the terminals
labeled +/- on the ISO-MOD 4-20mA module).

2. Using the arrow keys, increase the numerical value to increase

the current in the loop to 4mA. Decrease the value to decrease
the current in the loop to 4mA. Typical values range between
40-80 counts.

strength alarm, error alarm or totalizer/batching mode. The relays
are rated for 200 VAC max. and a have current rating of 0.5A
resistive load [175 VDC @ 0.25A resistive]. It is highly
recommended that a slave relay be utilized whenever the Control
Relay ISO-MOD is used to control inductive loads such as
solenoids and motors.

TOTALIZE mode configures the relay to output a 50 mSec pulse
(contact changeover) each time the display totalizer increments —
divided by the TOT MULT. The TOT MULT value must be a
whole, positive, numerical value.

For example, if the Totalizer Exponent is set to E0 (x1) and the
Relay Multiplier is set to 1, then the relay will pulse each time the
totalizer increments one count, or each single, whole
measurement unit totalized.

If the Totalizer Exponent is set to E2 (x100) and the Relay
Multiplier is set to 1, then the relay will pulse each time the display
totalizer increments or once per 100 measurement units totalized.

If the Totalizer Exponent is set to E0 (x1) and the Relay Multiplier
is set to 2, the relay will pulse once for every two counts that the
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 measuring reliably. See the Appendix of this manual for a list
of potential error codes.

The RS485 Module allows up to 126 MFX systems to be daisy­chained on a single three-wire cable network. Communications
are through a proprietary digital protocol, detailed in the Appendix
of this manual. All meters are assigned a unique one byte serial
number that allows all of the meters on the cable network to be
accessed independently. Baud rates up to 19.2k and cable
lengths to 5,000 feet [1,500 meters] are supported without the
need for repeaters.

SET ZERO—Calibrating Zero Flow

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.

4. Press ENTER.

5. The procedure is complete.

An alternative method for verifying and calibrating zero flow
when flow cannot be turned off is covered in Section 4 of this
manual.

UltraLink™ at the OUTPUT tab. Each relay can be configured
separately for one of four operations: Batch/Totalizer, Flow Rate,
Signal Strength or Error.

• Batch/Total mode configures the relay to output a 50 mSec
pulse (contact changeover) each time the display totalizer
inc remen ts divided by the Multiplier. The Multiplier value must
be a whole, positive, numerical value.

For example, if the Totalizer Exponent is set to E0 (x1) and the
Relay Multiplier is set to 1, then the relay will pulse each time the
totalizer increments one count, or each single, whole
measurement unit totalized.

If the Totalizer Exponent is set to E2 (x100) and the Relay
Multiplier is set to 1, the relay will pulse each time the display
totalizer increments or once per 100 measurement units
totalized.
If the Totalizer Exponent is set to E0 (x1) and the Relay
Multiplier is set to 2, the relay will pulse once for every two
counts that the totalizer increments.

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 UltraLink’s main Data Display.
At Page 1 of 3, press the Next> button. See Figure 4.10.

Signal
Quality

The Diagnostics screen provides valuable information regarding
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
bottom axis will roll over to the opposite axis.

In general, the more stable the signals appearing on the Diagnostics
screen are, the more stable the flow measurement readings will be.
Unstable signals, such as the signals shown in Figure 4.12, are
indicative of

• poor earth ground connections to the MagProbe,

• the probe electrodes not touching the conductive fluid in the pipe

(non-full pipe),

• electrodes that have become fouled with a non-conductive
substance or

• noisy power supply source.

Corel® Quattro Pro® for manipulation or graphical purposes.

NOTE: The spreadsheet programs listed above are limited to the
number of lines of data that can be imported. Very large files may
need to opened in a program such as Microsoft WordPad and/or
saved in two or more sections.

The data logger module contains a real-time clock that can be set
by clicking the Clock button on the top task bar; see Figure 4.17.
Activating the window compares the data logger clock to the clock
located in the PC. Adjustments can be made and uploaded to the
logger.

RS232 COMMUNICATIONS PROTOCOL

RS232 PROTOCOL
The RS232 works on a simple command data structure. The basic structure is:
[:] [cmd] [data] [bcc] [\n]
: Start of transmission, 1 byte

cmd Command Code, 1 byte
data Data or instruction
bcc Block check character, 1 byte
\n End of transmission, 1 byte

Command Codes:
The MFX has 4 basic command codes as follows:

01h Set flow data
05h Return flow data
11h Preset Non-volatile data
15h Return Non-volatile data

01h Set Flow Data: The data byte instructs the MFX processor to send flow data automati-

cally or to stop automatic sending. Automatic flow data is sent once per second as a
contiguous string followed by a \n. No bbc is returned

Data Information to be returned
10h Return velocity at 1 second intervals [:] [S] [+xx.xx]
11h Return flow rate at 1 second intervals [:] [F] [+xxxx.xx]
12h Return totallizer at 1 second intervals [:] [T] [+xxxxxx]
13h Return conductivity after being calculated [:] [Y] [xxxx]

1Fh Clear automatic sending

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.

[:] [15h] [bbc] [\n]

RS232 COMMUNICATIONS PROTOCOL

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.

union
{
structure struct
{
char VELU[5];
char FRUnit[5];
char Cndx;
char Scale;
unsigned char rly2_code;
unsigned char rl21_code;
unsigned char time_code;
unsigned char unit_code;
unsigned int cal20;
unsigned int cal4;
unsigned int SP_Hi;
unsigned int SP_Lo;
unsigned int access_code;
float PRB_FACT;
float MIN_FLOW;
float MAX_FLOW;
float VEL_CODE;
float RLY2_LL;
float RLY1_LL;
float RLY2_HL;
float RLY1_HL;
float MFE;
float TIMECODE;
float UNITCODE;
float CUTOFF;
float P_ID;
float TOT;
};
unsigned char[82];
}NVD;

Non-volatile data is transferred one character at a time as the data is contained in memory.

The entire block must be received as a whole without error or else the transmission will be ig­nored and an error code will be returned.
