Liquid-solid two-phase flowmeter

1.Product Function
Measure the flow of liquid-solid two-phase flow that is transported hydraulically through the pipe.

2.Product Features
1, advanced frequency AC excitation technology, microsecond sampling rate, the measuring system anti-solid material friction and magnetic conductive objects interference ability to achieve the accuracy of measurement results, real-time and stability of the organic unity, the measurement results from the solid The change of concentration and the influence of the magnetic conductive object.
2, long working life sensor, polyurethane lining, composite wear-resistant ceramic lined with the electrode as a whole pouring molding, with excellent anti-wear performance and overall watertight performance, to meet the high pressure, high wear performance requirements.

3.Product Composition
The system consists of two parts, the sensor and the host, as shown in Figure 7:




CWLL/CWBGS Greenwood solid-liquid two-phase flow measurement system
