The controller is a generalâpurpose 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 â 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.
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.
