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.

VERTICAL OR HORIZONTAL PIPE - Vertical pipe
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
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
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,
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
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.

PIPE

Mount the PC4 pipe clamp as illustrated on pipes

0.6" / 15 mm OD or larger. Stainless steel bands are
included for mounting on pipes up to 32" / 81 cm OD.

Additional stainless steel bands (by customer) may be
combined to mount on pipes up to 180" / 4.5 m OD.

SENSOR COUPLING

For permanent or temporary bonding, the following are recommended:

a) Dow Corning silicon compound #4 (supplied)

Additional supply: order Greyline Option CC

b) High Temperature compound (supplied with Sensor Option SE3H)

Additional supply: order Greyline Option AP-1W
c) Water-based sonic compound: Order Greyline Option CC30
d) Electrocardiograph gel
e) Petroleum gel (Vaseline)

The above are arranged in their order of preferred application.
d & e are only good for temporary bonding at room temperature.
DO NOT USE: Silicon RTV caulking compound (silicon rubber).

Use the PC4 pipe clamp (supplied) as illustrated above or
use a loop of electrical tape for temporary mounting.
Apply silicon coupling compound #4 to the coloured face
of the sensor. A bead, similar to toothpaste on a
toothbrush, is ideal. Do not overtighten (crush the
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
compound will create similar conditions.

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. Dow Corning Silicone Compound #4 as supplied with the PDFM 5.0 (and available from
Greyline Instruments) is recommended for semi-permanent installations.

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 20

PDFM 5.0 Portable 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.

Does the PDFM 5.0 require periodic recalibration?

No. PDFM 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.
