Liquid Level Sensor Applications

Senix ToughSonic® Liquid Level Sensors measure a liquid or slurry surface from above, using “non-contact” technology. The elevated mounting location of the sensor offers simple installation and excellent accessibility.

Senix sensors are more sophisticated and configurable than typical liquid level transmitters. Built-in circuitry provides flexible network connectivity so the sensor can interact simultaneously with other devices. Sensor control functions can be configured to optimize performance in your particular application using our PC-based SenixVIEW® configuration and analysis software.

ToughSonic sensors are weather-tight and rugged. Thousands are used worldwide, indoors and out, measuring tanks, canals, ponds, streams, wet wells and weirs. Senix ultrasonic sensors are used for flow monitoring, pump control, process control, liquid inventory, high-low alarms and environmental monitoring for flood detection and warning.

ToughSonic® Liquid Level Configurations

Our ultrasonic liquid level sensors are multi-talented and give you the flexibility to do more now and in the future. With configurable outputs, incident handling selections, networking and multiple simultaneous interfaces, ToughSonic sensors give you flexibility and value. Here are just some of the ways they are used:

ultrasonic liquid level sensor sending data to a digital display

Continuous liquid level data is transmitted to common analog or digital input meters and displayed in units such as height, volume or percent full.

Ultrasonic liquid level sensor sending data to a PLC

Liquid level data is transmitted, analog or digital, to user devices such as Programmable Logic Controllers (PLCs), Remote Terminal Units (RTUs) or computers which are part of your system.

Liquid level can be controlled by pumps or valves driven by sensor data. Sensor level hysteresis and time delays are used to create a simple level controller without additional logic devices.

One Ultrasonic liquid level sensors sending data to a display, a PLC and controlling a pump via a relay board simultaneously

Multiple simultaneous sensor outputs allow any or all of the above functions to operate concurrently.

Multiple ultrasonic liquid level sensors networked to a display and other equipment

All Senix RS-485 models can be connected in a multi-drop addressable network, and liquid level data can be collected by any control device capable of Modbus communications, such as a personal computer.
