Products-Liquid Filled Gauges



Howe Precision General Liquid-Filled Gauges are designed to perform in harsh environments, especially where pressure pulsations, vibration, and shock loads are a problem. The liquid also lubricates the internal movement that extends the life of the gauge. The her-metically sealed construction using a stainless steel case and crimped ring reduces the changes of leaks.As standard, these gauges feature a ventable top fill plug for pressure relief, ease of venting after installa-tion, field liquid filling, and allow the gauge to be moun-ted in a vertical or horizontal plane.
