What is the working principle of a solid flow meter?
Solid flow meter - suitable for measuring solid mass flow in metal enclosed pipelines with a wide range from kg/h to t/h. This system is suitable for online monitoring of solid flow rates such as powder, dust, small balls, and granules in pneumatic conveying or free falling bird hopper bodies (1nm-20mm). Solid flow meter, solid flow meter, microwave flow meter, microwave solid flow detector, microwave solid flow measuring instrument. The measurement principle of solid flow meter is based on the physical principle of Doppler effect. The sensor generates a microwave field inside the pipeline, and the microwave is reflected by the particles flowing inside the pipeline. The changes in frequency and amplitude can accurately measure the solid flow rate. Non flowing particles such as dust deposits will not be included in the calculation. The installation of EDIT and SWR is very simple and cost-effective. It involves welding a base onto the pipeline and threading the solid flow meter sensor into the base. The sensor is connected to a transmitter mounted on a DIN rail through a cable, and the transmitter outputs a 4-20mA measurement result signal, RS232
2, and RS485 interface. Calibration is very easy and can be completed through MF-SMART intelligent software. Weld a base onto the pipeline. Drill an 18mm hole in the pipeline and insert the sensor flush with the inner diameter of the pipe. For debugging and calibration, we need a laptop with the MF-SMART software we provide. The serial COM interface in front of the transmitter can be connected to a laptop, while the RS485 interface can be used to connect to a PLC system. Calibration can be performed through one
