Product • Installation Diagram

Many installation matters need attention ｜2017 Overall Upgrade ｜ HUAHAI Instrument will display for you

The diagram shows the requirements of vortex flowmeter for the length of the upstream and downstream straight pipe

(a)One 90 °elbow；(b) Concentric flaring； (c) Concentric contractive full-open valve;
(d) Two 90°elbows on different planes; (e) Half-open valve of regulating valve; (f) Two 90° elbows on one plane

Installation Precautions

Vortex flowmeter must ensure that the upstream and downstream straight pipe sections have the necessary length, as shown. In various data, the data are different, the reason may be that the vortex generation body has not been standardized, and the influence of difference in shape and size remains to be verified; It is not enough to study the necessary straight pipe section length for all kinds of bluff body, that is, it is not yet mature.Compared with the throttling type differential pressure flowmeter, this work is still in the initial stage.
