Ultrasonic Solid State Liquid Level Switch - Discontinued

LVU-A700 Series

300:1 Wet-to-Dry Ratio with 316 SS Sensor
Epoxy-Sealed Integral Electronics with Sensor
Low-Cost Replacement to Mechanical Float

Description

The LVU-A700 Series has been discontinued. Please see the LVSW-701 Series as a possible alternative or contact our Flow Engineering department.

The LVU-A700 Series solid state liquid level switch is a direct replacement for mechanical floattype liquid level devices. The switch employs proven ultrasonic technology and solid state integral electronics, and provides reliable operation in virtually any liquid, regardless of viscosity. This eliminates problems of stickiness and failure rate due to finite mechanical life inherent in the mechanical float design. The combination of fully epoxy-sealed electronics and ultrasonic sensing technology will provide years of maintenance free service.
