Nozzle Flow Meter

Nozzle Flow Meter
Nozzle flow meter is a standard differential pressure generating device. Used with a differential pressure transmitter, it measures flow of liquids, steam, and gases. It features lower pressure loss than orifice plates, is robust and durable, suitable for high-temperature and high-pressure fluids, and is widely used in power and chemical industries for steam metering.
- High degree of standardization, usable without actual flow calibration
- Smaller pressure loss than orifice plates, saving energy
- Robust and durable, suitable for high-temperature and high-pressure fluids
- Simple structure with no moving parts, long-term stability and reliability
- Available in standard nozzle (ISA1932) and long radius nozzle types
- Compliant with ISO5167 / GB/T2624 standards
Overview
Product Overview
Nozzle flow meter is a differential pressure generating device for flow measurement. The standard nozzle throttling device is used with a differential pressure transmitter to measure flow of liquids, steam, and gases. It is widely applied in petroleum, chemical, metallurgy, power, light industry, and other sectors. Its high degree of standardization allows use without actual flow calibration.
Types and Features
Compared with orifice plate flow meters, nozzle flow meters have smaller pressure loss, saving energy. They are more robust and durable, suitable for high-temperature and high-pressure fluids, and widely used in power and chemical industries for steam flow measurement. Available in standard nozzle (ISA1932) and long radius nozzle types, designed and manufactured according to ISO5167 or GB/T2624.
