Integrated Throttle Flowmeter

The Integrated Throttle Flowmeter (Integrated Orifice Flowmeter ) is a new type of flow instrument that integrates a traditional throttling device with an intelligent differential pressure transmitter into a single optimized assembly. It complies with GB/T2624-2006 national standard and ISO 5167:2003 international standard. During installation and use, no additional impulse piping is required; the device can be directly installed on the pipeline and put into operation. It is widely used for flow measurement and custody transfer of steam, natural gas, hot water, gases, and liquids.
