ZWRY-BK series throttling device produced by our company is the primary sensor of differential pressure flowmeter. By matching use with differential pressure transmitter and display instrument (or computer), the measurement of fluid flow can be realized, and the purpose of accumulation, display and control can be achieved. Because of its advantages of simple structure, convenient installation, reliable use, wide application range (The measuring pipe diameter of standard throttling device can be in the range of 50mm~1,200mm, and the applicable pipe diameter of special throttling device can be as small as 20mm and as large as 3,000mm. The measuring temperature can be as high as 550℃, the withstanding pressure can be as high as 32MPa, and there are many kinds of measuring media), and with the standard flow device that requires no separate calibration, it is one of the main instruments for flow measurement in the process of industrial automation control.
