Different types of DP Flow Meters

There are a number of different types of DP flowmeters, each of which has its own specialized function. Below you can see an overview of some the most common types.

  • Orifice plates
  • Venturi tubes
  • Venturi nozzles
  • Cone meters
  • Nozzles
  • Drag plates
  • Inlet flow meters
  • Wedge flow meters
  • Variable area meters

Advantages of DP flow meter

DP Flowmeters have a wide range of benefits that make them effective in use. Listed below are some of the different benefits:

  • Differential Pressure Flow meters can be used for the vast majority of gases and liquids
  • DP Flow Meters are cost effective
  • They can be used in all directions
  • DP flow meters are simple to manufacture and do not contain any moving parts, which makes them more long-lasting

Disadvantages of DP flow meter

DP flow meters also have certain disadvantages. Listed below are some of the disadvantages:

  • Under certain conditions, significant pressure losses can occur during use
  • The range is smaller than for most other types of flow meters
  • The output signal is non-linear with flow
  • The accuracy can be affected by the layout of the pipe

Miscellanous Flow 

For an accurate flow measurement, the need for a flow straightener might be necessary to reach acceptable conditions for flow measurement according to the ISO 5167-1 International Standard, which defines the “measurement of fluid flow by means of pressure differential devices”.

A sight flow indicator provides visibility of liquid flow in a pipe. Different mechanical features can help enhance flow observation.
