Echotel® Model 910 ultrasonic level switches utilize ultrasonic contact technology for measuring level in clean liquid applications. These integrally mounted level switches offer either an 8-amp DPDT gold flash relay or a 5-amp DPDT hermetically sealed relay.
Echotel® Model 940 and 941 Ultrasonic Level Switches are compact integral units that utilize pulsed signal technology to perform high- or low-level measurement in a wide variety of liquid applications.
Model 961 offers the ultimate solution to reliable single point liquid level measurement. This advanced switch uses pulsed signal technology for superior performance in difficult process conditions, and to provide excellent immunity from sources of electrical noise interference.
Model 962 is a dual point switch that can be used as a level controller, or to control pumps in an auto fill or auto empty mode. The tip sensitive lower gap performs well in aerated or foamy liquids, and can measure to within 1⁄4″ of the vessel bottom.
