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.
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 Ф 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.
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)
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:
V＝—————- ＋ C/a(m/s)
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
K/b, C/a are constants
When measuring, you can setT and then measure N, so the velocity and flow can be automatically
