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.
