KROHNE FLOW NOZZLE METER

The flow nozzle meter is designed for accurate long-term stable flow measurement of liquids gases and steam, especially in high velocity applications with the risk of erosion or cavitation. Typical applications are feedwater, steam, condensate or refined products in various industries – from power plants, refineries to chemical processing facilities to oil and gas production or CCS.

Flow nozzle meters offer a low remaining pressure loss, require only short straight inlet/outlet pipe sections and have an excellent long-term stability compared to other DP flowmeters. KROHNE offers the complete flow metering solution including flow nozzle, DP transmitter, valves, accessories, engineering, testing and documentation from one single source. The flow nozzle assembly typically comes calibrated with the nozzle installed in a metering section for offering the highest accuracy.

A number of different flow nozzle types are available to meet the exact application and regulatory requirements, e.g. a throat tap long radius nozzle according to ASME PTC 6, available with flanges or butt weld pipe connections. Also calibrated meter-runs with flow conditioner, upstream and downstream pipe sections and the flow nozzle according to ASME PTC or similar standards for performance testing are available.

The sophisticated OPTIBAR DP 7060 and the OPTIBAR DP 3050 DP transmitters are the perfect companion products for this DP flowmeter solution. They are 3D linearised and ensure advanced performance even at high static pressures. The OPTIBAR DP series has an outstanding long-term stability and a low total cost of ownership with a reduced need for field calibrations.
