Product details
A nozzle flowmeter is a differential pressure generating device for measuring flow rate, which can be used in conjunction with various differential pressure gauges or transmitters to measure the flow rate of various fluids in pipelines. The standard nozzle throttling device is used in conjunction with differential pressure transmitters to measure the flow rates of liquids, vapors, and gases, and is widely used in sectors such as petroleum, chemical, metallurgical, power, and light industry. Especially suitable for boilers:Main feedwater pipeline, main steam pipeline, reheated steam pipeline
