Engineered primary flow elements
For flow measurement with DP transmitter
Flow sections and standardized DP flow elements such as nozzles, Venturi tubes, wedge and cone meters (according to ISO 5167, ASME MFC-3M, ISO TR 15377 etc.)
Traceably calibrated, excellent long term stability
Completely pre-assembled and customized designs adapted to the specific application requirements
Flow nozzle
Engineered primary element for DP flow measurement of high velocity, non-viscous or erosive fluids
- ISA 1932, long radius and Venturi nozzles
- Standards: ISO 5167, ASME MFC-3M or ASME PTC 6
- Only short inlet and outlet runs required
Venturi tube
Engineered primary element for DP flow measurement of liquids, gases and steam with the lowest residual pressure loss
- Machined or welded design (internally machined) according to EN ISO 5167, ASME MFC3
- Lowest residual pressure loss of all DP elements
- Only short inlet/outlet runs required
- From basic to special wet gas applications and high pressure conditions
Cone meter
Engineered primary element for DP flow measurement in applications with limited installation space
- Meter run with integrated cone and single taps according to EN ISO 5167-4
- Rugged solution for difficult media and harsh operating conditions, e.g. in oil and gas applications
- Designed for large diameters (up to 24″), demanding flow profiles, high pressures and temperatures
Wedge meter
Engineered primary element for DP flow measurement of high viscous and solids-containing fluids
- Meter run with integrated V-shaped wedge
- For slurry and fibrous liquids containing solids or gases
- Reynolds number down to 300
- Applicable for bi-directional measurement
