The general purpose guard capacitance point level switch provides high or low liquid level detection of water based conductive liquids with light coating, crystallizing or scaling characteristics. RF guard eliminates the coating signal path between the active and reference electrodes. The submersible PP liquid level sensor can be mounted inside the tank or through non-metallic tank walls as a high level alarm or low level alarm.

Guard circuit optimizes performance in coating type media
Compatible with Switch-Pak fitting for vertical tank installation

The general purpose non-intrusive capacitance level switch provides reliable liquid level detection of water based conductive liquids with non-coating and/or scaling characteristics. The liquid level sensor is bracket mounted on the exterior wall of non-metallic tanks and applied as a high level alarm or low level alarm.

Non-intrusive level detection through plastic or fiberglass walls. 

Three different bracket materials makes attachment to tank easy.

Great for non-metallic or FRP tanks up to 1” thick. 

Reliable Heavy-Duty Design
Chemtrol True Union Ball Check Valves heavy-duty stub-acme thread seal carrier retaining ring provides more reliability than other designs. Standard features - Teflon® seats, assembled with silicone-free lubricant.
Horizontal or Vertical Operation
Designed to operate effectively in horizontal or vertical positions. Equally effective in checking back flow from head pressure on the discharge or suction sides of pumps. Maximum Internal Pressure of 150 psi at 73° F for the most demanding applications of 1/2"- 4" valves.
Screen Assemblies
PVC and CPVC screens are available for easy conversion to foot valves, in all sizes.
