5VDC Water Flow Velocity Meter / Water Flow Speed Meter Temperature 0~40℃
HT Handheld Reader
HT-B Type Handheld Reader
1. Introduction
Portable current velocity meter is an equipment used in water conservancy for velocity flow measurement, designed for hydro-logical stations,mining factories, environment monitoring stations, farm irrigation, hydro-geology and so on. Portable current velocity meter is composed of propeller velocity meter, HT type handheld reader and measuring bars. Full set of instruments is in the aluminum-alloy box.When using, you can assemble it as a body and connect the signal cable, then the velocity of every open channel can be measured. And it can automatically display the velocity and present the flow of sectional areas.
The instrument is light and convenient with simple structure. It has low power consumption, complete function, high automation degree, stability and reliability, which complies with the national measurement standards.
