Liquid-Filled Pressure Gauges for Oil and Gas Applications


Within the oil and gas industry, high-quality, reliable pressure gauges are essential in production and refining processes. They are crucial to maximizing quality and assuring the safety of both equipment and personnel. Pressure gauges must be able to withstand harsh environmental conditions and process materials while still maintaining their accuracy and reliability. Also, some gauges are mounted on high vibration or pulsating equipment, which, if not selected appropriately, can cause the internal parts to wear out and dramatically shorten the life of the gauge.


WESEN Technologies has several oil and gas gauge solutions available for quick delivery in its models of liquid-filled gauges. Liquid filling of a pressure gauge protects the internals of the gauge from vibration and pulsation that are encountered when the gauge is mounted on pumps, compressors, or machine tools. In addition to protecting against this movement, the liquid fill makes the gauge easier to read because it dampens the pointer action and provides lubrication, extending the life of the pressure gauges.


The wetted parts of the Models M02 pressure gauges are 316 stainless steel, allowing them to be used with many harsh chemicals without the risk of damage to the gauge. WESEN also offers a full line of diaphragm seals for the most caustic applications. The gauge case is made from 304 stainless steel and features a crimped-on window as well as a liquid fill plug at the top of the gauge for easy filling. Pressure ranges include vacuum-only gauges, compound gauges to 300 psi, and pressure ranges from 0 to 15,000 psi are available.


The Model M02 also features 316 stainless steel wetted parts and is available in low, center back, and low back mounting options. The two accuracy options are 1.6 % of FS for 2-1/2” gauge and 1.0% of FS for 4” and 6” gauges. Pressure ranges are available from 30” Hg. through 23,000 psi, as well as vacuum and compound ranges.


WESEN is one of the world’s leading suppliers of high-quality, competitively priced pressure gauges, diaphragm seals, temperature gauges, and thermowell fittings. WESEN’s product line includes a wide range of pressure gauges, from vacuum to 23,000 psi, in single or dual scale dials. Gauge sizes range from 1.5” to 10”, with brass, 316 stainless steel, or Monel internals.
