Value / Description |
|
Measurement Principle |
The HNF100-C basic modular ultrasonic flowmeter is a series of high-precision ultrasonic flowmeters based on the ultrasonic time-difference principle, featuring 4-byte IEEE754 floating-point operations. It utilizes intelligent integrated hybrid signal processing and is widely used for long-term online measurement of various liquids. It can be installed without interrupting the pipe flow and, when equipped with a temperature sensor, can achieve heat measurement. It is widely applied in process control, production measurement, trade settlement, and has penetrated into industries such as water supply and drainage, metallurgy, petrochemicals, water conservancy projects, and energy monitoring. |
