Mid-West Instrument Inc. has introduced a new line of tank level gauges designed for cryogenic/liquefied gas for both stationary and mobile applications. The new 115/116 gauges feature a dry bellows design with internal bi-directional relief valves with no liquid fill required to protect the unit from over-range. The 115/116 gauges are also good for the He and H2 service. The company said the LHe and LH2 range gauges are 30 Ib lighter than competitive units, allowing more products to be transported.

Differential pressure ranges are from 0- to 10-in. H20 to 0- to 415-in. H20 (0- to 25-mbar to 0- to 1-bar).
