High Performance Propeller Type Current Flow Meter Easy Installation

         Strength of Metlan

          After nearly ten years of sustainable development, target at the Chinese market,Metlan                               continuously invest in the product designing,research and manufacturing.We develop a supply                   chain of production,warehouse,quality,sales.Also we have created our own production,business               model and explored a unique way of spot supplying from scratch,from small to large,from weak to               strength so that we can keep the promise to deliver the goods.Your visit and valuable advice are               our forward motivation.

         Technology of Metlan

          Following nearly 30-year of technology experience of several veteran instruments bases and                     combining with the foreign advanced production technology and technical indicators.We are the                 first to propose the concept of faction of southern China and northern China and get much process           from the technology research and development cooperation projects with Nanjing University.Much             experience has been accumulated from practices to deal with custom'technical problem leisurely.

Description:

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 spin paddle velocity sensor ( or other type spin

cup and screw propeller velocity apparatus), HT type velocity flow meter 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.

Measuring principles:

This instrument is designed based on the theory of areas of open channel’s velocity.After 

measuring the velocity, the flow can be get:Q=V·S(S is sectional area)

Velocity measurement

When measuring velocity, the spin paddle type rotor flow meter will be pushed by waterpower. 

The built-in signal apparatus produces RPM signal. The formula below can calculate velocity:        

(K/b)N

                 V—————-    C/a(m/s)

                         T

V: the average velocity (m/s)

B/K:the waterpower pitch of blades 

a/C: velocity constant

T: lasting time(the unit is s)

N: the number of signals in T time 

S: sectional area

Q: flow

K/b, C/a are constants

When measuring, you can setT and then measure N, so the velocity and flow can be automatically 

calculated.
