Please help select an vortex flow meter
Thread Content
There is a set of equipment on site designed to use 1.8 t/h of steam. Now, it is intended to install an vortex flow meter on the steam pipe, which has a diameter of DN100. Which brand and model of flow meter should be chosen?
In your question regarding 1.8 t/h, it is also necessary to know the temperature and pressure of the steam. At different temperatures and pressures, the density of steam varies, which in turn results in different ranges for flow measurement. As for brand selection, Emerson is an option; its measurement performance is good.
Knowing the pipe diameter and flow rate is not enough; pressure and temperature must also be known, as well as the connection method, whether temperature and pressure compensation is available, and if any other communication methods are required. I manufacture vortex flow meters with a precision of 1.5%. You provide the data, and I will carry out a detailed selection to ensure quality at a competitive price. I don’t know much about imported products; domestic ones are probably much cheaper, it’s up to you to decide.
Pressure 0.5 MPa, temperature 160℃
Temperature 160°C, pressure 0.5 MPa

The flow meter should be selected as DN65.
For vortex flow meters, it is recommended to choose well-known brands; those from small workshops are not suitable. At 160 degrees Celsius, it is recommended to use a split-type design. Both vortex flow meters and electromagnetic flow meters have recommended flow rates; find a sample to determine an appropriate diameter (inner diameter) for that flow rate. Additionally, pressure loss and pipe stress must also be taken into consideration. That is, a selection should be made between DN50 and 100.
Does the pipe diameter of DN100 need to be reduced to DN65? Is there any evidence?
