Snubbers for pressure gauges

Pressure gauge snubbers are intended to suppress the effect of pressure pulses and pressure peaks, which are common reasons for gauge failure. Porous snubbers incorporate a fixed mesh disk. Piston snubbers are supplied with five pistons for use with a variety of media. Adjustable pressure gauge snubbers are provided with an adjustable needle valve that enables the operator to restrict the flow as operating conditions may demand even when the snubber is in service.

Siphon

A siphon is a tube that allows liquid to travel upward, above the surface of the origin reservoir, then downwards to a lower level without using a pump. When a certain amount of water moves over the bend in the siphon, gravity pulls it down on the longer leg lowers the atmospheric pressure in the bend of the siphon.

3-Way-Manifold

A three-valve manifold is a device that is used to ensure that the capsule will not be over-ranged. It also allows isolation of the transmitter from the process loop. It consists of two block valves – high pressure and low pressure block valve – and an equalizing valve.
