Clamp-on Ultrasonic Flowmeter
Installation in 3 Steps, in Approximately 3 Minutes
Using the QuickClamp design, the sensor can be quickly mounted on the outer surface of the pipe without cutting the pipe or modifying the process. Thanks to the special ultrasonic contact pad, no ultrasonic coupling gel is required during installation.
3 Steps ≈ 3 Minutes No Pipe Cutting No Gel Required

Flow measurement ranges are specified by LORRIC based on 20 °C water and PVC pipe as reference conditions. When selecting a model, the actual pipe outer diameter must be checked together with the nominal pipe size. The FU-ES sensor is mounted externally on the pipe using a clamp-on installation method.

MEASUREMENT & PROCESS
Installation Method
External Pipe Mounting · Clamp-On No Pipe Cutting No Ultrasonic Gel Required
Thanks to the QuickClamp mounting system and special ultrasonic contact pad, the sensor can be quickly installed on the outer surface of the pipe.
Compatible Pipe Materials
Metal Pipes UPVC PPH PVDF
Especially for copper pipes, the actual pipe outer diameter should be checked instead of relying solely on the nominal pipe size.
Compatible Fluids
Water, oil, chemicals and various liquids
The fluid to be measured must be free from solid particles / impurities and air bubbles.
Fluid Temperature
0…+85 °C
The pipe surface must be free from ice formation.
Velocity Measurement Range
Recommended: ±0.3…6.0 m/s Measurable: ±0.1…10 m/s
Flow Measurement Range
Varies depending on the selected FU-ES model and pipe diameter. Current model-specific measurement ranges are listed in the FU-ES Ultrasonic Flow Meter Models table above.
LORRIC calculates the flow ranges using water at 20 °C and PVC pipe as reference conditions.
Measurement Accuracy
±3.0% RD · 10–100% F.S. ±0.3% F.S. · 0–10% F.S.
Accuracy values were obtained at 25 °C in a controlled laboratory environment with defined pipe and fluid conditions after zero calibration of the device. Measurement accuracy may vary under actual field conditions.
