The controller is a general‐purpose ultrasonic level controller that provides the end user the ability to control up to three unique devices (pumps, valves and/or alarms) through three relays, namely – Relay1 (DPDT, 2 form C), Relay2 (SPDT, 1 form C) and Relay3 (SPDT, 1 form C). The controller uses three push-buttons, SET, UP and DOWN for configuring the relay operation(s). All of the relays can be used for controlling valves, pumps or alarms.

[AG Echo]  Ultrasonic level sensor which provides accurate range detection, automatic calibration and adaptive noise cancellation in software provide reliable and record measurement. All sensor used 4- stage op-amp based low noise amplifier, second order narrow band pass filter, peak-detector and low-pass filter circuit for detecting even the weakest of the reflected sonar signals. Various output options like pulses width, serial analogue 4 to 20 mA, 0 to 5 Volt etc. are available. Interface circuit options provide RS 232, 4 to 20 mA loop, 0 to 5 V DC, buzzer/relay and seven segment LED display. Accessories like mounting bracket rubber washer/nut faster etc. provide quick design and installation support.
