2. Make Certain your pressure, temperature, and other requirements are compatible with the meter. ’

3. Select a suitable location for installation to prevent excessive stress on the meter which may result from:
a. Misaligned pipe
u.

The weight of related plumbing

c. “Water Hammer”, which is most likely to occur when flow is suddenly stopped, as with quick closing and solenoid operated valves.

If

necessary, a surge chamber should be installed. This will also be useful in high pressure start-up situations.

d. Thermal expansion of liquid in a stagnated or valve isolated system. If necessary, install valving which will allow the meter to be drained

when it is not in use.
NOTE: In closed thermal transfer or cooling systems, install the meter in the cool side of the line to minimize meter material expansion and
contraction and possible related fluid leaks.

4. Handle the meter carefully during installation. Use an open end or adjustable wrench on meters with hexagonal fittings, and a leather,

plastic or fabric strap wrench on meters with round fittings.
a. Do not use pliers or wrenches to hold the metering tube.
b. DO NOT OVERTIGHTEN PLUMBING CONNECTIONS INTO FITTINGS. Overtightening will cause the fitting to

d. Do not expose the meter to solvents or solvent fumes (eg., PVC cement).

5. If the meter has a metering valve, it is not recommended for use as a shut-off valve if the system ’s operating pressure is above 15

6. Install the meter vertically with the inlet port at the bottom.

7. It is recommended that meters used in pressure gas and chemical service (other than 14.7 PSIA) be sufficiently shielded to protect
individuals and property from flying debris in the event of meter failure.

inspect the meter for damage that may have occurred during shipping. Immediately report any damage to the shipping agent.

RECOMMENDED INSTALLATION PRACTICES

Water hammer and surges can be damaging to any flowmeter and must always be avoided.

Water hammer occurs when a liquid flow is suddenly stopped, as with quick closing and solenoid -operated valves. Surges occur when flow

suddenly begun, as when a pump is turned on at full power or a valve is quickly opened.
Liquid surges are particularly damaging to flowmeters; if the pipe is originally empty. To avoid damaging surges, fluid lines should remain full (if
possible) and pumps should be brought up to power slowly and valves opened slowly. In addition, to avoid both water hammer and surges, a

surge chamber should be installed.
