Series 40000 Liquid Level Indicator

Protectoseal Series No. 40000 Liquid Level Indicators are used for accurate liquid level gauging of fixed or floating roof tanks storing oil, water, solvents and other products. 

The units are designed and constructed to permit simple, easy installation on “tanks-in-service” or “tanks-out-of-service”, and to provide a maximum of trouble-free service. 

This particular type Indicator is especially recommended for applications requiring a low cost, low maintenance method for liquid level gaging. 

The Indicators are float-actuated, and have a steel target that runs vertically up and down a calibrated board to register the tank contents. 

The board is mounted outside of the tank and has bold, legible markings to permit quick, convenient readings.
