Issues with the use of mass flow meters
Thread Content
An automatic loading controller system is used in my loading system. My operating media include tar, medium oil, and crude phenol – all of which have the characteristic of solidifying easily. My problem now is how to address the issue of reduced accuracy in the use of mass flow meters due to the solidification of these media after they are loaded My pipeline is heated. I hope everyone can offer useful suggestions; thank you!
If a mass flow meter must be used, opt for a high-temperature resistant type, maintain the temperature, or purge it with steam after use. A purging pipeline system can be designed to work automatically or manually.
Is it feasible to use low-pressure nitrogen purging to displace the fluid while it is not solidified?
Is it feasible to use low-pressure nitrogen purging to displace the fluid while it is not solidified? Answer: It is possible if high-temperature nitrogen is used. The effect at room temperature is very poor.
Mass flow meters are not suitable in this situation; their purging effect is poor, and they get clogged frequently. It is recommended to use probe flow meters, which can be manually cleared online. We use those made by Tieling Guangming
