I. Product Introduction
 
1. Product principle
 
The working principle of propeller current meter is that when the water flow acts on the propeller of the inductive element of the instrument, the propeller not only produces rotary motion, but also has a certain functional relationship between the rotary rate "n" and the flow rate "V", V=f (n).
 
2. Product use
 
JC-HS portable hydrological current meter, in line with the national open channel measurement standard, is specially developed for hydrological survey and farmland irrigation workers to do velocity and flow measurement. It can be used to measure and calculate the velocity and discharge of various open channels and pumping stations. The whole set of instruments consists of high sensitivity LS1206B rotary slurry current meter, measuring rod with length of 4 x 0.4 m and TYJ hydrological current meter, which are placed in aluminum alloy instrument box with size of 47 x 37 x 12.
