Liquid level sensing is crucial in many industries to maintain precise fluid volumes, prevent overflow or dry-running, and ensure process consistency. By monitoring fluid levels in applications like storage tanks, and water treatment systems, operators can maintain safety standards, optimize resource use, and reduce downtime.
How to Monitor Liquid Level with TPS Devices
Use a Third-Party Ultrasonic Sensor
One of the popular vendors is MaxBotix. They offer a range of ultrasonic sensors that easily interface with TPS devices via RS232 interface. Use the Module Tibbit #01 for RS232 and the Connector Tibbit #20 (or #21) for terminal connections.

Did You Know? MaxBotix sensors can be used for much more than just measuring water levels. Sensors exist for measuring distances to snow surfaces, solid objects, etc. They are great for counting people, vehicles and many other applications. Importantly, AppBlocks makes working with them extremely easy.
For Modbus devices with power requirements higher than 5V, you may need to supply separate power.
