The Transit-Time Ultrasonic Flow Meter, also known as Time-of-Flight (TVT) ultrasonic flow meter, is a non-intrusive flow measurement technology widely used for clean liquid applications. It operates on the principle of measuring the time difference between ultrasonic signals transmitted in the direction of flow and against the flow direction.

Open the cover located at the right lower side to connect to DC power terminal. Follow the wiring diagram to connect: RTD input (only for Energy Model), RS485, 4-20mA, Transducer (Upstream transducer, Downstream transducer), Relay Output, OCT Output.

For double-shielded transducer cable: "+" on the blue wire, "-" on the white wire and "shield" on the shield.

The ST501 Fixed Ultrasonic Flow Meter is equipped with multiple communication and output options to ensure seamless integration into various industrial control systems. These outputs enable real-time data acquisition, remote monitoring, and control of flow-related processes.
