Fluid hammer and surges can destroy any pressure transducer and
must always be avoided. A pressure snubber should be installed to
eliminate the damaging hammer effects. Fluid hammer occurs
when a liquid flow is suddenly stopped, as with quick closing sole-
noid valves. Surges occur when flow is suddenly begun, as when
pump is turned on to 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 opened slowly. To avoid damage from both
fluid hammer and surges, a surge chamber should be installed and

a pressure snubber should be installed on every transducer.
Symptoms of fluid hammer and surge's damaging effects:
1. 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.
2. Pressure transducer output remains constant regardless of
pressure.
3. In severe cases, there will be no output.
