Measurement principle and usage scenario

Measurement Principle

A number of global invention patent applications are pending.

The LORRIC clamp-on ultrasonic flowmeter uses the ultrasonic time difference to measure the flow, and uses the linear relationship between the ultrasonic transmission time difference between the upstream and downstream of the pipe and the flow rate to measure the flow. Due to the one-piece clamp-on structure, it can be installed without interventions in the pipe, compared with the in-line flowmeter, it can also provide the highest chemical resistance and leak-proof performance. Compared with the traditional ultrasonic flowmeter, since there is no need to adjust the position of the upstream and downstream probes, it can be installed quickly, and also greatly reduces the training required for installers.

Due to the inevitable dimensional tolerances of all mass-manufactured pipes, there may still be tiny flow data when the fluid does not flow, or the device displays a data of 0 but there is still a small amount of fluid passing through.

This product uses ultrasonic measurement, so it is necessary to avoid the interference of ultrasonic transmission caused by a large number of solid foreign objects, a large number of air bubbles, and crystals in the fluid. At the same time, try to avoid strong magnetic field interference near the device.

The ultrasonic flowmeter measures the flow correctly only when the fluid shows stable flow. Please choose the installation location according to the guidelines.

Usage Scenario

This product provides flow measurement of liquids that do not contain a large amount of impurities in full pipe in industrial environments. The installation location should allow the fluid in the pipe to be as stable and fully developed as possible. The temperature of the pipe can be up to 100 degrees Celsius, but the ambient temperature should allow the device to work between -10 and 60 degrees Celsius. The device also provides IP66 water repellent design and cannot be used under water. The product material is PC, PMMA, PPS, PA66, stainless steel 304 and PEEK, which can resist light chemicals, but should not be exposed to chemicals for a long time or in large quantities.

In order to reduce the difficulty of installation, each model corresponds to a range of pipe outer diameters. Please select the model according to the pipe specifications to be installed. Some combinations of pipe materials and wall thicknesses that are unfavorable for ultrasonic transmission may make it difficult to measure the flow rate (for example, too thick PVDF pipes or some metal pipes). Please consult the sales staff before purchasing.
