Problems with flow meters for measuring oil-coal slurry flow
Thread Content
Typically, the oil-to-coal ratio in oil-coal slurry is 1:1, the temperature is around 160°C, the viscosity ranges from 200 to 400 MPa/s, and the density is approximately 1.130. The density of the oil itself lies between 0.85 and 1.00. Conventional differential pressure flow meters (such as wedge-type or venturi types) do not provide accurate measurements, and their pressure taps are prone to clogging. Are there any contactless flow measurement methods available, such as ultrasonic, electromagnetic, or mass flow meters? If there are any products with proven performance in such applications, please recommend them. Thank you. For the oil-coal co-processing project, manufacturers of flowmeters are requested to send the relevant materials to the email address zxj@catech.com.cn
Forgot to mention that the coal powder particle size is <150μm
The mass flow meter should be available; you can consult the manufacturer.
Conventional differential pressure flowmeters (wedge, venturi) provide inaccurate measurements, and their pressure taps are prone to clogging. If neither of these two can be measured accurately, are there any other flow meters? Just wait for an expert to provide you with a more reliable flow meter
It shouldn’t be easy to choose then; the other options don’t fit well.
Actually, I’m here to watch! :lol
Mainly, the poster always wants something that requires no maintenance!
For water-coal slurry, there are electromagnetic flowmeters equipped with special wear-resistant rubber linings, and the electrodes are also wear-resistant. I’m not sure if oil-coal slurry is feasible; it is recommended to contact the manufacturers of electromagnetic flowmeters, as they will have better solutions.
Is it possible to use a differential pressure diaphragm pressure transducer? Has the reason for the blockage been identified?
