Liquid Filled Pressure Gauges

A liquid-filled gauge contains a fluid that dampens vibration, protecting internal components and providing a steady needle reading. A dry gauge has no fluid and is more susceptible to damage from pulsation and vibration, which can cause pointer flutter. Liquid-filled gauges are preferred for harsh industrial environments.

Use a liquid-filled gauge in applications with significant mechanical vibration or pressure pulsation, such as on pumps, compressors, or hydraulic systems. They are ideal for harsh environments common in oil & gas, manufacturing, and processing industries where accuracy and durability are critical for operational safety.

Yes, they can be configured for corrosive media by using a diaphragm seal. The seal isolates the gauge's internal mechanism from the process fluid. This protective barrier ensures the instrument is not damaged by aggressive chemicals or slurries, extending its operational life and maintaining measurement integrity.

They are engineered with heavy-duty, one-piece case-to-socket connections for superior durability. This design withstands the rigors of upstream, midstream, and downstream operations, ensuring reliable performance in one of the world's most demanding industrial applications. Compatibility with protective accessories further enhances their suitability.

A one-piece case-to-socket connection eliminates a potential leak path and weak point found in multi-piece designs. This solid construction provides superior strength and resistance to mechanical stress and vibration. It's a critical feature for ensuring long-term reliability in demanding applications like oil and gas processing.

To enhance performance, we recommend accessories like needle valves for throttling pressure, snubbers to dampen pulsation, and diaphragm seals for protection against corrosive media. For temperature monitoring in pressurized systems, thermowells are also available. Our team can help select the right accessories for your specific application.
