Calculation Sheet for the Balance Flow Meter(sample)

Questions:Balance Flow Meter

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

Min Normal Max
Flow range 200 Nm3/h
2500 Nm3/h 3600 Nm3/h


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:
