The Series CLG Cryogenic Level Gage uses a flexible elastomer diaphragm design that provides a simple, accurate, direct acting, low range differential pressure indicator. The CLG is a dry gage, as opposed to liquid filled models which may be damaged or lose accuracy from expansion or contraction when exposed to temperature shocks, typical in cryogenic applications. The Series CLG is available with an aluminum, brass, or stainless steel body, and is perfect for liquid level, line loss, and valve drop applications.
