Portable Ultrasonic Flow Meter: The TF1100-CH series Handheld solution
No pipe cutting. No system shutdown. Portable clamp-on flow measurement on existing pipelines.
1. What Makes the TF1100‑CH Handheld Ultrasonic Flow Meter Stand Out?
The TF1100‑CH adopts advanced transit‑time technology for high‑precision flow measurement. As a battery‑powered non‑invasive handheld unit, its clamp‑on transducers mount externally on pipe surfaces without pipe cutting or modification. Free from direct media contact, it delivers reliable, fouling‑free measurement for diverse liquids including potable water, chemicals, sewage and cooling water, unlike traditional inline flow meters.

3. How Does the TF1100‑CH Transit‑Time Ultrasonic Flow Meter Work?
Different from Doppler ultrasonic flow meters, the TF1100‑CH transit‑time flow meter uses two transducers acting as both ultrasonic transmitters and receivers, clamped externally on a closed pipe at a specific distance. It calculates liquid velocity by measuring the transit time difference of ultrasonic bursts sent between the two sensors. Three installation methods can be selected according to pipe and liquid conditions:
Ultrasonic beam travels across the pipe twice. Most commonly used for standard pipe sizes.
Sound wave crosses the pipe four times, suitable for small diameter pipelines.
Transducers fitted on opposite sides, sound passes through the pipe once. Ideal for large pipes or high turbidity media.
4. Where Can the TF1100‑CH Handheld Ultrasonic Flow Meter Be Applied?
Thanks to its unique transit‑time measuring principle, the TF1100‑CH performs excellently in many scenarios where conventional flow meters encounter limitations. It is widely adopted across these industrial sectors:
