Harwil In-Line Liquid Level Switches
Eliminate nuisance switch tripping with a wide range of differentials.
- Large differentials are immune to wave action and turbulence (L-21VCR models)
- Single-point switch provides pump up/pump down level control
- Withstands corrosive and particle-contaminated working fluids
This series of liquid level switches are easy to install, operate and maintain. Through-wall NPT process fittings and NPT electrical ports facilitate integration into existing systems. Operation checks and troubleshooting require only a multimeter.
Wetted materials are fiberglass-reinforced PPS and Hastelloy® C. Switch types and materials of construction resist corrosion and increase durability, making them suitable even for seawater and filtered sewage.
