What does FS stand for?

So simple and safe to use - just plug in and the float switch automatically turns off or on as the water level drops or rises.

The unit detects the liquid level either via a float switch, an analog sensor, an integrated pneumatic pressure sensor or a bubbler system.

The brochure reviews potential oil and gas sensing solutions, including APG s HU intrinsically safe Hammer Union pressure transmitter, PT-400 pressure sensor, PT-500 hydrostatic pressure level transmitter, PG-7 digital pressure gauge, LPU-2428 ultrasonic level sensor, LPU-2127 ultrasonic sensor, KA Kari cable suspended float switch, PC-10K hydraulic pressure comparator/calibrator and the RPM resistive chain level sensor.

The range includes piston valve designs, piston inline designs and paddle designs for flow control, plus a float switch for level control.

Standard features include X,Y,U,V linear motor drives with glass scale feedback, automatic dielectric level float switch, electrolysis free circuit, and a large 15" LCD monitor.

A float switch is available that fits through a 3/4-in.

For those units that are in the attic or in an upstairs closet, it is imperative that a float switch is available.

Forget these checks, which means you don't check the position of the ALL TEST float switch on the fuel cell shut off panel before refueling, and you could damage the shutoff valve.
