What type of flow meter is suitable for steam pipes?
Thread Content
We mainly use it in exhaust pipelines. The exhaust pressure is generally 0.25 MPa, with a range of 0.196–0.49 MPa. The rated temperature is 204 degrees, and the maximum temperature is 239 degrees. The pipe diameter is DN426mm with a wall thickness of 10mm; the maximum exhaust volume is 65–70 T/H. Could someone experienced advise me on what type of flow meter would be both inexpensive and suitable for use in this case?
A vortex flow meter will do; however, an ABB model will work as well
For common applications, in large-diameter cases, options include orifice plates, balanced orifice plates, Anubas, etc.; for small-diameter cases, vortex flow meters are mostly used.
For insert-type vortex flowmeters, I recommend using insert-type capacitive vortex flowmeters; for more details, please contact us at xp0631@126.com
The most economical and cost-effective option is a orifice plate plus differential pressure transmitter; temperature and pressure compensation can be added if mass flow rate needs to be measured. Moreover, the maintenance costs in the later stages are much lower; I do not recommend products such as Aonuba or insert-type vortex flow meters. If pressure loss is a concern, then use a venturi tube as the throttling element.
Many people use vortex flowmeters, and they are quite useful.
The steam pipe diameter is DN426 mm; it’s a bit tricky to choose a flow meter for such a large diameter. . . . . .
A long-neck nozzle combined with a differential pressure transmitter will also work~~ You can take a look at what the design institute has designed to find out more
An orifice plate is better for measuring gas flow rate.
What is the steam discharged for? If there are no requirements regarding pressure drop, an orifice plate will suffice
