Severe Service 40MM & 50MM SEVERE SERVICE GAUGE • Copper Alloy Internals • Glycerine Filled • Center Back Mount Only Marsh Instruments Liquid-Filled Gauges are designed to perform in rugged and harsh environmental conditions - especially where pulsation and vibration is a problem. Liquid Filled Gauges offer a significant cushioning and dampening effect, reducing pointer flutter and internal gauge damage. Liquid Filled Gauges feature a ventable top fill plug and can be mounted on a horizontal or vertical plane. The hermetically sealed construction reduces the chance of leaks and makes field filling an easy option. Typical applications include refineries, chemical, oil & gas, marine and OEM processes.
