Portable  digital meter counter 

Introduction

HT type portable velocity flow meter (Portable velocity apparatus) is an equipment used in water conservancy for velocity flow measurement, designed for hydrological stations, mining factories, environmental monitoring stations, farm irrigation, hydrogeology and so on.

Portable velocity flow meter is composed of LS1206B spin paddle velocity sensor (or other type spin cup and screw propeller velocity apparatus), velocity measuring instrument and 0.4 m x 4  16 measuring bar.

Full set of instruments are in the aluminum-alloy password boxes. When using, you can assemble it as a body and connect the signal line, then the velocity of every open channel can be measured. And it can automatically display the velocity and preset 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. It is the new portable velocity measuring instrument in China.
