Main steam flow transmitter
Thread Content
The main steam flow transmitters in the waste heat boilers at our factory keep breaking down; we have to replace one of them almost every week. Are there high-temperature resistant flow transmitters? Or is there any way to help solve this?
What specific process conditions are there, and what are the parameters? .
What are the process conditions and parameters? What kind of flow meter was it, and what caused it to break down so frequently?
Transmitters are not prone to breaking; first, you need to ensure that your parameters are appropriate and that the installation was done correctly. Another possibility is that the transmitter you’re using is of poor quality – opt for a product from a reputable manufacturer instead.
What is the temperature, and are there any highly corrosive acids or bases?
Try using a capillary? Or add a condensation tank
When the temperature is high, medium isolation is necessary. Won’t it burn out the measuring diaphragm? Could it be that the transmitter’s electronic module is damaged?
In our factory, orifice plates together with differential pressure transmitters are used to measure the steam flow in the waste heat boilers; an isolation tank and long pressure transfer pipes are used to connect these components. I think there should be no problems as long as the condensation effect is good. Our factory uses differential pressure transmitters made by Chuanyi Yokogawa
Hehe, what the person above said is right. For steam flow meters used in waste heat recovery, they consist of orifice plates along with differential pressure transmitters; an isolation tank is also required, as steam condensate is needed. There are no other questions
The design institute initially recommended vortex flow meters, but before we could use them, we switched to differential pressure meters.
It’s almost definitely a quality issue; several units have been used and there are no problems with them, but the accuracy isn’t quite ideal due to issues with the throttle components.
