Description

Liquid Filled Pressure Gauge is particularly suited to measuring points with high dynamic loads, such as fast load cycles or vibrations. The design and materials of construction provide reliable service in applications where  pressure pulsation, vibration, and wide variations in ambient temperatures are present.

Protection
– If pressure gauges are to be used for steam service, a siphon tube filled with water must be installed between gauge and line to prevent live steam from entering the Bourdon tube.
– A gauge cock should be installed in the pressure line. This might be the standard shut-off valve or a needle valve for throttling pressure pulses.
– If severe pulsation exists, the gauge should be protected by adding a throttling orifice
screw in the gauge socket or by addition of a pulsation damper, such as a snubber.
– A diaphragm seal should be used in applications where process media should not come in contact with gauge.
