CONNECTIONS:
POWER INPUT: The standard model requires AC power input between 100 to 240 VAC 50/60Hz. No
adjustments are necessary for voltages within this range. Connect L (Live) N (Neutral) and AC Ground.
Optional DC input model requires 9-32 VDC/10 Watts. Connect to + and - terminals.
Optional Thermostat and Heater modules are available rated for 115 VAC or 230 VAC.
IMPORTANT NOTE: To comply with CSA/UL electrical safety standards, AC power input and relay
connection wires must have conduit entry to the instrument enclosure. Installation requires a switch,
overcurrent fuse or circuit breaker in the building (in close proximity to the equipment) that is marked
as the disconnect switch.
Risk of electric shock. Loosen cover screw to access connections. Only qualified personnel
!
should access connections.
Note: Use of instrumentation over 40°C ambient requires special field wiring.

SENSOR MOUNTING LOCATION
The position of the sensor is one of the most important considerations for accurate flow measurement.
The same location guidelines apply to Doppler as most other types of flow meters.
VERTICAL OR HORIZONTAL PIPE - Vertical pipe
runs generally provide evenly distributed flow. On
12 O'CLOCK POSITION WITH
LOW GAS CONTENT
Horizontal pipes and liquids with high concentrations
of gas or solids, the sensor should be mounted on the
side (3 or 9 o’clock position) to avoid concentrations of
gas at the top of the pipe, or solids at the bottom. For
3O'CLOCKP OSITION WITH HIGH
GAS OR SOLIDS CONTENT
liquids with minimal gas bubbles (e.g. potable water)
the sensor should be mounted on the top of a horizontal
pipe (12 o’clock position) to obtain the best signal

results, the transducers must be installed on a straight
run of pipe, free of bends, tees, valves, transitions,
insertion probes and obstructions of any kind. For
most installations, ten straight unobstructed pipe
diameters upstream and five diameters
downstream of the transducers is the minimum
recommended distance for proper operation.
Additional considerations are outlined below.
• Do not, if possible, install the transducers downstream from a throttling valve, a mixing tank, the
discharge of a positive displacement pump or any other equipment that could possibly aerate the
liquid. The best location will be as free as possible from flow disturbances, vibration, sources of heat,
noise, or radiated energy.
• Avoid mounting the transducers on a section of pipe with any external scale. Remove all scale, rust,
loose paint, etc., from the location prior to mounting the transducers.
• Do not mount the transducers on a surface aberration (pipe seam, etc.).
• Do not mount transducers from different ultrasonic flow meters on the same pipe.
• Do not run the transducer triaxial cables in common bundles with cables from other instrumentation.
You can run these cables through a common conduit ONLY if they originate at the same flow meter.
• Never mount transducers under water.
IMPORTANT NOTE: In some cases, longer straight runs may be necessary where the transducers are
placed downstream from devices which cause unusual flow profile disruptions or swirl. For example:
modulating valves, or two elbows in close proximity and out of plane.

DFM 6.1 Doppler Flow Meter
SENSOR MOUNTING
Prepare an area 2" wide by 4" long (50mm x 100mm) for sensor bonding by removing loose paint, scale
and rust. The objective of site preparation is to eliminate any discontinuity between the sensor and the
pipe wall, which would prevent acoustical coupling.
A PC4 Sensor Mounting Kit is supplied with each Greyline flow meter. It includes recommended
coupling compound and a stainless steel mounting bracket with adjustable pipe straps.

SENSOR COUPLING
For permanent or temporary bonding, the following are recommended:
a) Super Lube ® (supplied)
Additional supply: order Greyline Option CC-SL30 or your local home improvement store.
b) Water-based sonic compound: Order Greyline Option CC30
c) Electrocardiograph gel
d) Petroleum gel (Vaseline)
The above are arranged in their order of preferred application.
c & d are only good for temporary bonding at room temperature.
DO NOT USE: Silicon RTV caulking compound (silicon rubber).
COMPOUND
Use the PC4 pipe clamp (supplied) as illustrated on the
previous page. Apply Super Lube ® to the coloured face of
the sensor. A bead, similar to toothpaste on a toothbrush, is
ideal. Do not overtighten (crush the sensor).
SENSOR
The sensor must be fixed securely to the pipe with coupling material

between the sensor face and the pipe. Sensor installation with
excessive coupling compound can result in gaps or voids in the
coupling and cause errors or loss of signal. Insufficient coupling

Over time temporary coupling compounds (e.g. Petroleum Gel) may gradually sag away from the sensor
resulting in reduced signal strength and finally complete loss of signal. Warm temperatures, moisture
and vibration will accelerate this process. Super Lube ® as supplied with the DFM 6.1 (and available
from Greyline Instruments or home improvement stores) is recommended for semi-permanent
installations.

Corrective Action:
• Check Sensor connections
• Use direct connection with 12 AWG wire to
nearest Ground pole (<1 ohm resistance).
SENSOR CABLE RESISTANCE TEST
Unplug the green sensor terminal from the Doppler board and connect the sensor wires as shown. With a
multimeter, perform resistance checks for each set of wires. One single loose terminal may cause false
readings.
Test across shield and core of each wire: TMTR (black/white) and RCVR (black). Resistance should be
around 82.5K ohms for any cable length. High readings indicate an open circuit and low readings
indicate a short or partial short in the sensor cable.

COMMON QUESTIONS AND ANSWERS
The pipe vibrates. Will it affect the flow meter?
Common vibration frequencies are far lower than the sonic frequencies used by the Greyline flow meter,
and will not normally affect accuracy or performance. However, applications where very weak Doppler
signal is present (when sensitivity is adjusted to maximum and signal strength is low), accuracy may be
affected by pipe vibration, or the flow meter may show readings under no-flow conditions. Attempt to
relocate the sensor on a pipe section where vibration is reduced, or arrange pipe mounting brackets to
reduce vibration at the sensor mounting location.
The flow meter must be installed in a high noise environment. Will this affect operation?
Greyline flow meters are designed to discriminate between environmental noise and the Doppler signal.
High noise environments may affect the flow meter’s performance where low signal strength and/or low
flow velocities are being measured.
Will pipe corrosion affect accuracy of the flow meter?
Yes. Rust, loose paint etc. must be removed from the outside of the pipe to provide a clean mounting
position when installing a Doppler sensor. Severe corrosion/oxidation on the inside of the pipe may
prevent the Doppler signal from penetrating into the flow. If the pipe cannot be cleaned, a spool piece
(PVC recommended) should be installed for sensor mounting.
What effect do pipe liners have on the flow meter?
The air gap between loose insertion liners and the pipe wall prevent the Doppler signal from entering the
flow. Better results can be expected with bonded liners such as cement, epoxy or tar, however an on site
test is recommended to determine if the application is suitable for a Doppler flow meter.
Why is Doppler only recommended for liquids containing suspended solids or gases?
The Doppler sensor transmits sound into the flow stream which must be reflected back to the sensor to
indicate flow velocity. Gas bubbles or suspended solids act as reflectors for the Doppler signal. As a
guideline, Greyline Doppler flow meters are recommended for liquids containing solids or bubbles with
a minimum size of 100 microns and a minimum concentration of 75 ppm. Most applications (except
potable, distilled or deionized water) will meet this minimum requirement.
Can the sensor be submerged in water?
Yes, for short periods of time or by accident, but it is not recommended for continuous operation. The
sensor is constructed to withstand submersion to 10 psi without damage, but external liquid moving in
contact with the sensor can be interpreted as flow and cause false readings.
What is the purpose of the Signal Strength Display?
Doppler signals of very low strength are not accepted or processed by the instrument. This feature
assists in rejection of environmental noise and vibration. Use the display to evaluate signal strength in
your application. Strong signals will increase in percentage to a maximum of 100% or greater.
Page 29
DFM 6.1 Doppler Flow Meter
Can I change the length of the sensor cable?
Yes. Greyline Doppler’s design allow cable lengths up to 500 ft (152 m) with no loss of signal strength.
Extended cable (Greyline Option DXC) should be installed in rigid or flexible conduit for mechanical
protection. Use only Greyline shielded coaxial pair (RG174U) cable. Cable junctions should be made
through a terminal block and housed in a watertight metal junction box (Greyline Option DJB). BNC
coaxial connectors (TV cable type) are not recommended for cable splices.
Does the DFM 6.1 require periodic recalibration?
DFM 6.1 calibration does not drift over time. The solid state sensor has no moving parts to wear and
affect calibration. The Doppler flow technique generates an ultrasonic signal proportional to the velocity
of flow. All Greyline timing/counting circuits use crystal-controlled frequency references to eliminate
any drift in the processing circuitry.
ISO 9000 or similar quality management systems may require periodic and verifiable recalibration of
flow meters. DFM 6.1 Doppler Flow Meters may be returned to Greyline for factory calibration and
issue of a new NIST traceable certificate. Refer to the ‘Product Return Procedure’ section of this manual
for return instructions.
