Flow counter of the dynamic pressure partial flow type

It is composed of a flow tube, a flowmeter, a general pressure guide tube, and a pressure guide tube that has a side hole on one end and has a closed side on the other end. The entire flow in the main tube can be measured out with the steps that firstly the partial water flow in the main tube is introduced into the flowmeter of the tributary tube and surveyed the average flow rate thereof and that secondly the overall result is calculated out according to the corresponding ratio, based on the partial flow principle. The flowcounter is provided with the tributary tube and the flowmeter thereon. The flowcounter makes advances on smaller fluid resistance, large flow flux, lower energy consumption, higher measuring accuracy.
