Implexx Ultrasonic Water Level Sensor

• A digital, SDI12 ultrasonic water level transmitter or 4-20mA option
• Low cost, accurate, reliable and robust device for long term installations
• Measure level of any water or liquid surface with this non-contact device
• Ideal for rivers, dams, lakes, tanks, hydrology, urban management, scientific research

The Implexx Ultrasonic Water Level device is ideal for the non-contact measuring of water level of any surface. The device transmits narrow beam (5°) ultrasonic pulses (i.e. sound waves with a frequency above the upper limit of human hearing). The pulses rapidly transmit to the target and reflect off the surface and back to the device. The time is then converted into distance to measure water level.

Flexible Outputs

SDI-12 or 4-20 mA? The Implexx Ultrasonic Water Level device can transmit data via either protocol. The Implexx Ultrasonic Water Level device is suitable for a range of interfaces including data loggers, PLC's, IoT devices, LoRaWAN, NB-IoT, WiFi, modems, Arduino, Raspberry Pi, and many more.

The Implexx Ultrasonic Water Level device is suitable for the ES-SYS range of monitoring systems.

Easy to Install and Configure

The Implexx Ultrasonic Water Level device has an easy to use, touch pad and LCD display where the device can be easily configured. There are also a range of SDI-12 commands to operate and interface the device with any data acquisition system.

The standard cable length is 5m yet this can be extended to potentially hundreds of metres, if required.

Principle of Operation

The sensor transmits ultrasonic pulses to the measurement target. The pulses are reflected from the surface of the target and received back by the sensor. The running time is converted into the distance and it shows as level or volume on the display.

D=(C*T)/2
D: distance
C: sound velocity
T: time of flight
Distance: from the sensor bottom to surface of the target
Level: from the bottom of storage to surface of the target
Empty: from the sensor bottom to the bottom of storage
