Transit-Time Type Ultrasonic Flow Meter

A Transit-Time Ultrasonic Flow Meter measures flow by sending ultrasonic sound waves through the pipe both upstream and downstream. The difference in travel time of these waves is directly related to the velocity of the fluid inside the pipe. This time difference is used to calculate flow rate accurately.

This principle is best suited for clean or low-solid liquids.

Transit-Time ultrasonic meters by Saitechflow can be:

• Clamp-On Type – Installed outside the pipe
• Inline Type – Installed as an integral part of the pipe
• Insertion Type – For large pipelines

Each version uses the same ultrasonic transit-time measurement technology.

⭐ Working Principle – Transit-Time Ultrasonic Technology

Transit-Time Ultrasonic Flow Meters work on the time difference method. Two transducers are placed on the pipe—one acts as a transmitter while the other works as a receiver. Ultrasonic pulses are sent with the flow and against the flow.

How It Works:

1. Sound waves traveling with the flow move faster.
2. Sound waves traveling against the flow move slower.
3. The meter computes the difference in travel times.
4. This time difference is proportional to the flow velocity.
5. Flow rate and total volume are calculated.

This method is extremely reliable and offers high accuracy when the liquid is clean or has low solid content.
