WARNING!

Read Before Installation

Fluid hammer and surges can destroy
any pressure transducer and must
always be avoided. A pressure snubber
should be installed to eliminate
damaging hammer effects.

Fluid hammer occurs when a liquid
flow is suddenly stopped, as with
quick-closing solenoid valves. Surges
occur when flow is suddenly begun, as
when a pump is turned on at full power
or a valve is quickly opened.

Liquid surges are particularly
damaging to pressure transducers if the
pipe is originally empty. To avoid
damaging surges, fluid lines should
remain full (if possible), pumps should
be brought up to power slowly, and
valves should be opened slowly. To
avoid damage from both fluid hammer
and surges, a surge chamber, and a
pressure snubber should be installed on
every transducer.

Symptoms of fluid hammer and surge's
damaging effects:

a) Pressure transducer exhibits an

output at zero pressure (large zero
offset). If zero offset is less than
10% FS, user can usually re-zero
meter, install proper snubber, and
continue monitoring pressures.

b) Pressure transducer output remains

constant regardless of pressure.

c) In severe cases, there will be no output.
