PCWJ Series Vortex Flow Meter
■ The structure of Vortex flow meter is simple and strong, no movable parts, and it is very stable.
■ Simple installation and easy maintenance
■ Wide measuring range, the ratio is up to 10:1
■ Low pressure loss and operating costs.
■ When measuring the volume of fluid, compensate as required, replace parts without re-calibrate the flow meter.
The series of Vortex Flow Meter is based on Von Karman’s Vortex Principle, which adopts piezoelectric crystal as testing components. It is a new kind of stress detecting vortex flow meter. It has the advantages of wide range rate, high accuracy, low pressure loss, good medium generality, pulse signal output proportional to flow, convenient to connect with computer etc. As the detector probe of sensor and the vortex generating body are installed separately, and the high temperature resistant piezoelectric crystal doesn’t contact with medium, so the instrument is of simple structure, good generality, and high stability.
PCWJ series Vortex Flow Meter can be used to detect and measure the flow of all kinds of gas, fluid and steam.
