Professional Current Velocity Meter 0.05~7.0m/s Measuring Range
Lake Channel River Test
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.

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.
