SENSOR MOUNTING LOCATION
The position of the sensor is one of the most important considerations for accurate Doppler flow
measurement. The same location guidelines apply to Doppler as most other types of flow meters.
Before permanently mounting a Doppler sensor onsite testing is recommended to determine optimum
mounting position. Use the sensor coupling compound (supplied with each Greyline flow meter, or
petroleum gel, acoustic compound or electrocardiograph gel). Take several readings around the axis of
the pipe and then at several points upstream and downstream from the selected position, checking for
consistent readings. Avoid high or low reading areas. Mount the sensor where consistent (average)
readings were obtained or continue testing on another pipe section.
12 O'CLOCK POSITION WITH
VERTICAL OR HORIZONTAL PIPE - Vertical pipe
LOW GAS CONTENT
runs generally provide evenly distributed flow. On
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
3 O'CLOCK POSITION WITH HIGH
GAS OR SOLIDS CONTENT
of gas at the top of the pipe, or solids at the bottom.
For liquids with minimal gas bubbles (e.g. potable
water) the sensor should be mounted on the top of a
HAS EVENLY DISTRIBUTED FLOW
VERTICAL PIPE USUALLY
horizontal pipe (12 o’clock position) to obtain the best
signal strength.
VELOCITY INCREASING DEVICES: Generally the sensor must be mounted away from flow
disturbances such as valves, pumps, orifice plates, venturis or pipe inlets and discharges which tend to
increase flow velocity. Velocity increasing devices often cause cavitation, or rapid release of gas
bubbles, and readings both up and downstream may show much higher velocity. As a guideline, mount
the sensor at least 20 diameters upstream or 30 diameters downstream from velocity increasing devices.
Required distance from a velocity increasing device will vary in applications depending on the flow
velocity and the characteristics of the liquid itself.
TURBULENCE INCREASING DEVICES: Elbows,
SENSOR MOUNTS 6 DIAMETERS
UPSTREAM OR 10 DOWNSTREAM
FROM AN ELBOW
flanged connections and tees tend to introduce
desirable conditions of an evenly distributed flow
profile with some air or gases entrained in the flow.
Sensor mounting 6 pipe diameters upstream and 10
FLOW
diameters downstream from these disturbances is
generally optimum.
The sensor is designed to mount longitudinally on a straight section of pipe. Do not attempt to mount it
on bends, elbows or fittings.

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 in a plastic applicator and a stainless steel mounting bracket with adjustable pipe
straps.

SYNCHRONIZATION
Synchronization may be required to prevent interference (readings with no flow or "cross talk") in
applications where more than one DFM 5.0 Doppler sensor is used in close proximity. Synchronize
DFM 5.0 flow meters only if sensors from separate DFM 5.0 flow meters are mounted on the same pipe.
To synchronize one or more DFM 5.0 flow meters use twisted, shielded pair cable, 22AWG or heavier.
Connect SYNC + of one DFM 5.0 to the SYNC + of the next unit. And connect SYNC - of one DFM
5.0 to the SYNC - of the next unit, etc. Connect shield to Transducer GND on all units as illustrated
below.
No changes in DFM 5.0 hardware setup or software are required. The instruments manage
synchronization connections automatically.

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. Relocate the sensor in a more quiet environment if possible.
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.
Page 24
DFM 5.0 Doppler Flow Meter
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.
Can I change the length of the sensor cable?
Yes. Technological advances in Greyline Doppler 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 5.0 require periodic recalibration?
No. DFM 5.0 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.
