Overview
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.
Product features and options depend on device configuration: Contact us to make sure that your preferred functionality can be combined in one device.
- Flowmeter assembly for high requirements of accuracy and long-term stability
- Short straight inlet/outlet pipe section requirements and low remaining pressure drop
- Manufacturing and calibration capabilities up to 48''
