Clamp on Flow Meter
The clamp on ultrasonic flow meter measures by attaching sensors to both sides of the pipe, requiring no cutting or interruption of flow during installation—ideal for situations where downtime is not an option.
This non-invasive method is ideal for contamination-free measurements in semiconductor processes, PCB manufacturing, and water treatment, offering high linearity and consistent accuracy at all flow rates.
ToF (Time of Flight) Principle
Using the formula Flow Rate = Cross-Sectional Area × Flow Velocity, accurate flow measurement depends on precisely measuring fluid velocity. The FU-ES ultrasonic flow meter, with EchoSense technology, calculates velocity by measuring the time difference of ultrasonic waves traveling with and against the flow (Time of Flight).
As shown in the diagram, ultrasonic signals move faster with the flow (A to B) and slower against it (B to A) due to the fluid's influence on wave speed. By measuring this time difference, the flow velocity is determined, and combined with the pipe's cross-sectional area, the flow rate can be accurately calculated.

Complete all settings in 1 click
With EchoSense technology, forget about worrying over pipe materials, inner and outer diameters, thickness, liquid speed of sound, probe placement, and installation complexities. With just one click, we've simplified it all, making installation and setup a breeze. Say goodbye to the hassle!
Automatic Pipe Specification Matching
EchoSense technology features a built-in database of common pipe specifications, including PVC, PP, PVDF, and stainless steel. After installation, one click matches the installed pipe with the database, automatically setting material, outer diameter, and wall thickness. This streamlines installation by removing manual configuration and reducing errors, solving the issue of uncertain pipe specs in traditional setups.
Remarkable measurement accuracy
LORRIC's exclusive algorithm maintains high precision, earning Germany's TrigasFI certification. Test charts show FU-ES measurement accuracy between ±3.0% OR for 10%-100% of full scale (F.S.) and ±0.3% F.S. for 0%-10% of F.S. For a DN25 pipe (3-300LPM range), a 100LPM reading (10%-100%) has a ±3.0% error (97-103). A 20LPM reading (0%-10%) has a ±0.3% error (19.91-20.09).
Multiple Communication Outputs
FU-ES supports various communication modes like Analog output with self-powered 16-bit 4-20mA, Modbus RTU RS485, 2-wire photoelectric switch signal (compatible with NPN/PNP). No need for additional communication modules – we've got you covered!

* The measurement accuracy is established in a controlled laboratory environment where the pipe and fluid conditions are set and the instrument is calibrated to zero before conducting tests at 25°C. Although statistical results are obtained under these conditions, there may be variances in accuracy when used in customer environments.
** Incorrect installation when rotating the screen by loosening the screws around it may affect the IP66 waterproof protection.
