@ Hitesh : Syphon is used for STEAM Application, Not to
reduce pulsation.

Answer / sajid ali khan

First let me correct the Question itself a little. It
should read " Which mechanical devices are used to minimise
or dampen pulsations in pressure gauges".

Answer:
Process Pulsations expecially those at the dicharge od
reciprocating pumps can be very problematic for
measurement. The pulsations can also make pressure reading
difficult.Frequently, they can even damage pressure gauges
beyond repair and it is important to curtail these such
pulsations.

Normally three devices are used.1) Pigtails, which are
simply a mild steel pipe or Stanless steel tube bent in a
full circle, it is installed between the pressure tapping
and the gauge, with inside diameter a little less than the
tap dia. The Process Pressure dampens while traversing
though the pitail.
2) A restriction damper, that has sometimes a variable
restriction of a conical piece inside a matching chamber.
The process pressure has to squeeze throughh the annualar
space and demapens.
3) A hollow cylindrical chamber, that acts as capacity to
reduce the pulsations.
