Porous balanced orifice flowmeter

3. Ministry of Chemical Industry standard GJ516-87-HK06.

Features:
▲The structure of the throttling device is easy to copy, simple, solid, stable and reliable in performance, long in service life and low in price.
▲Orifice plate flowmeter calculation adopts mature standards and processing
▲Wide range of applications, all single-phase flows can be measured, and some mixed-phase flows can also be applied.
▲The standard throttling device can be put into use without actual flow calibration.
▲The integrated orifice plate is easier to install, no pressure inducing pipe is required, and can be directly connected to differential pressure transmitters and pressure transmitters.
