Sample of Calculation Sheet for the Balance Flow Meter
Questions:
We would like to retrofit existing vortex meter to balance flow meter,
Detail setup as below:
Pipe Size / SCH: 2 In /40
Pipe ID: 52.502mm
Flowing Pressure: 16 Barg
Flowing Temperature: 35-45 DegC
Medium:100% Nitrogen gas
Temperarure : 30-45Degc,
Purpose: Nitrogen gas flow measurement
Can you please issue a calculation sheet for the balance flow meter?
Answer:
We are a balance flow meter supplier from China with good price. Balance Flow meter is a kind of throttling device similar like orifice plate; it needs DP, pressure transmitter, RTD and flow computer to realize the flow measurement.
Comparing to traditional orifice plate, balance flow meter can bear higher temperature and pressure applications, also with better accuracy and lower pressure loss.
Thanks for your detailed information, and please see below calculation sheet according to your provided technical specifications:
Wish above data sheet will help you to choose a correct flow instruments.
