The new MagneStar magnetic liquid level gauge from L.J. Star Inc., of Twinsburg, Ohio, provides accurate liquid level readings at pressures ranging from vacuum to 4,700 psig, and temperature from -328 to +842 degrees F. Liquid level readings are conveyed via a two-tone indicator attached to the exterior surface of the gauge chamber. The gauge chamber spans the height of the corresponding tank, vessel or boiler. The level identified by the indicator is directly analogous to the liquid level in the vessel.
