Mid Range Pump Control Ultrasonic Level Sensor
Simple Ultrasonic Sensor
These ultrasonic transmitters are programmable via the DCR controller series, and are often used for level-based pump control.
Description
Inexpensive Control
The DST ultrasonic level sensors work in conjunction with the DCR controllers to give you a simplified, stand-alone system for level measurement and control.
Field-Proven Solution
This system of DST liquid level sensors and DCR controllers has proven itself for over a decade, and still solves applications today.
Flexible
Because there are several sensors and controllers to choose from, using DST ultrasonic sensors give you plenty of options for your application needs.
