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.

Orifice Plates
without Taps

DP flow with orifice plates and orifice flanges.

Orifice Plates
with Taps

Orifice plates also including pressure taps.

Meter Runs with
Flow Elements

Flow elements including inlet and outlet pipe length.

Flow
Nozzles

For small pressure loss and installation length.

Venturi
Tubes

For minimum pressure loss and maximum flow.

Restriction
Orifices

Defined pressure loss by a restriction orifice.

Cone Meters

Cone meters for short inlet straight lengths.

Wedge Meters

Wedge meters for fluids with solid particles.

Pitot Tubes

Low pressure losses and easy installation.

Accessories

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
• Costs

The following table shows the characteristics of each flow element type based on above paramters:
