Mini Gauge – Compact Tubular Level Gauge

The John Moncrieff Ltd Mini Gauge is a simple, effective valveless tubular level gauge. Its connection ends screw directly into the vessel, making it a fast, no-nonsense solution for compressor lube-oil tanks, small water tanks, and general service on a wide variety of fluids. Seal materials and sight-tube options are specified to suit the duty.
