1、 Product Overview:
The OW-CBL pipeline ultrasonic flowmeter is an instrument that measures the flow rate of liquid inside a circular tube based on the principle of "velocity difference method". By adopting multi pulse technology, signal digital processing technology, and error correction technology, the flow meter can better adapt to the industrial environment, making measurement more convenient, economical, and accurate. The product has reached the advanced level in China and can be widely applied in fields such as petroleum, chemical, metallurgy, power, water supply and drainage.
2、 Characteristics of OW-CBL Pipeline Ultrasonic Flow Meter:
1. The unique signal digital processing technology makes the instrument measurement signal more stable, has strong anti-interference ability, and measures more accurately.
2. No mechanical transmission components are easy to damage, maintenance free, and have a long lifespan.
3. Circuit optimization, high integration, low power consumption, and high reliability.
4. Intelligent standard signal output, user-friendly human-machine interface, multiple secondary signal outputs for you to choose from.
5. Pipeline type small pipe diameter measurement is economical, convenient, and has high measurement accuracy.
