Point Level sensors provide simple low tank level input for controllers and solenoid metering pumps. They are used to stop your metering pump when chemical level is low or for direct input to your Walchem WebMaster or WebAlert for remote low level indication. (read more)

Sitron's model CLF-(1 up to 5) level switch is the most commonly specified conductive level switch. The CLF-(1 up to 5) can accommodate up to five 316S.S. fixed rods for five different levels of control. The rods are isolated with a Teflon joggle and can also be coated with Teflon, epoxy or nylon when the probe is applied in aggressive or sticky mediums prone to build up. (read more)

Madision Company's engineered designs can provide a liquid level switch for tank applications with slight changes in the level at which the switch signal is needed, to accommodate multiple tank designs or conditions. (read more)

K-TEK's LS Series Mechanical Level Switches are the most rugged and durable liquid point-level detection products in the industrial marketplace today. K-TEK innovations such as the one-step switch point adjust and the hermetically sealed/dual compartment switching mechanism have eliminated the need for bulky housing covers that are associated with cracking, moisture ingress, high temperature fatig...
