Selection of flow meters
Thread Content
For a range of 1 m3, what type of flow meter is suitable? Can an integrated orifice plate be used? What is the minimum flow rate at which an integrated orifice plate flow meter can be utilized?
First, there is no medium name or status; second, there are no requirements regarding pressure or differential pressure; third, there is no time unit for flow rate. How can other sea friends give you suggestions? When asking questions of others, be specific; otherwise, no other travelers will want to help you.
Is it a request for help or a discussion? If you need help, specify the process conditions clearly; there’s no need for discussions.
I sent it in a bit in a hurry, so I didn’t have time to provide all the parameters: flow rate is up to 1 m3/h, temperature is 35 degrees, gauge pressure is 0.8; it’s mixed pentane in liquid form, with a density of 0.7 g/cm3. The pipeline is made of carbon steel, with DN50 dimensions and PN16 pressure rating; the viscosity is unknown
If high precision is not required, you can try a metal tube rotor
This operating condition cannot be calculated using an orifice plate (DN50); the resulting β value does not meet the requirements. Take a look at the rotor; it seems that even with a rotor, necking will occur
What about using a non-standard orifice plate? I’ve checked some information and found that such plates can be used for DN15 as well
