Discussion on the selection of flow meters for such medium operating conditions
Thread Content
The process medium is gas (with main components such as CO, CO2, CH4, H2, etc.). The gas production process involves carbonization, which means that the gas contains impurities such as dust and medium- to low-temperature coal tar. I would like to ask everyone how to select a flow meter for such operating conditions? It would be best to introduce it by combining principles and structural forms.
Common orifice plates, adjustable types, and vortex flow meters can all be used.
We are gas; our composition is similar. Accuracy is higher when the flow rate is high, and the orifice plates need to be inspected regularly
The gas is dusty and dirty; the Pitot and Vortex flowmeters, which are designed to prevent clogging, should work well in such conditions.
Using a vortex flow meter or an eccentric orifice plate
Due to the presence of tar, contact-based measurement methods are not the preferred choice. External clamping ultrasonic flowmeters can be used, but when the pressure is too low, titanium or plastic tubes must be used as the measurement tube.
