DP Flow Elements
Differential pressure flow elements can be manufcatured for all kinds of requirements. We created an overview of the different DP flow elements and their respective advantages and disadvantages.
with Flange Taps
DP flow with orifice plates and orifice flanges.
with Integral Taps
Orifice plates also including pressure taps.
Meter Runs with
Flow elements including inlet and outlet pipe length.
For small pressure loss and installation length.
For minimum pressure loss and maximum flow.
Defined pressure loss by a restriction orifice.
Cone meters for short inlet straight lengths.
Wedge meters for fluids with solid particles.
Low pressure losses and easy installation.
Condense vessels, thermowells, valves etc.
Comparison of DP Flow Elements
Depending on the requirements of the meausurement, different DP flow elements may be more suitable for a particular case. These parameters are crucial for identifying the correct element type:
- Measuring uncertainty
- Maximum pressure loss acceptable
- Maximum installation length
- Process conditions
The following table shows the characteristics of each flow element type based on above paramters:
|Measuring uncertainty||Pressure loss||Inlet/outlet length||Costs|
