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.

Propeller Velocity Meter

LS1206B Type Propeller Velocity Meter

1. Introduction

LS1206B Type Propeller Velocity Meter is used to measure flow rate of scheduled testing point.

This instrument has the following advantages: small volume, light mould, compact form and convenient to use. It is applicable to investigate water resource, perform runoff experiment and use in irrigation ditch, small and big rivers. Meanwhile it is widely used to test pipe flow measurement efficiency of small and medium-sized mercury station, efficiency experiment of hydraulic machinery, and sewerage monitoring.

As a CBL-1 mercury station flow meter, this instrument is identified by the Ministry of Water Resources of the People’s Republic of China in 1983. It is approved that this instrument is applicable to measure flow rate of medium and small single mercury station. It is of easy installation and operation, stable performance, reliable operation and the precision complies with grade C precision in the international standard ISO-2548-73 Flow Rate Test. It is deemed that this instrument is small invested and high yielded after being adopted by users nationwide. In 1983, this instrument is awarded the fourth prize of scientific and technological progress by the Ministry of Water Resources of the People’s Republic of China.

The instrument is widely used in small channel flow measurement in field irrigation. It can work normally in irrigation area of 20kg/m³ sediment concentration because of its fine spindle dynamic sealing.

When it is modified slightly in installation structure, this instrument can be applied in ship velocity measurement.
