ultrasonic flowmeter

 Measurement principle

The ultrasonic flowmeter is an industrial-grade time-difference ultrasonic flowmeter. It employs the latest industrial-grade FPGA chip with a 700,000-gate array, greatly improving the signal sampling frequency and bubble tolerance. The self-developed TGA technology enables it to handle more complex logic and calculations, achieving more accurate and faster measurements. The flowmeter can tolerate non-continuous bubbles or impurities within 5 seconds. At the same time, it retains the characteristics of ultrasonic flowmeters—simple and convenient installation, allowing installation without pipe breaking, water stoppage, or work interruption.

Where:
V = velocity of the measured fluid
M = number of ultrasonic reflections
D = pipe diameter
θ = angle between the ultrasonic signal and the fluid
Tup = time for the signal transmitted from the downstream sensor to reach the upstream sensor
Tdown = time for the signal transmitted from the upstream sensor to reach the downstream sensor
△T = Tup – Tdown

Application range

Municipal sewage measurement, crude oil flow measurement, cementing mud flow measurement, oilfield oily wastewater flow measurement, water injection rate measurement for oil wells, raw water measurement from rivers, lakes, and reservoirs, tap water flow measurement; petrochemical process flow detection, industrial circulating water flow measurement; water consumption measurement in production processes, ore slurry flow measurement, pulp flow measurement, chemical liquid flow measurement, cooling circulating water flow measurement, generator coil cooling water flow measurement (ultra-small pipe diameter), fruit juice flow measurement, milk flow measurement.
