Description:
LS20B 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.
Applications:
LS20B type propeller flowmeter is a kind of large range hydrological flowmeter, which is applicable
to measure high, medium, and low flow rate of rivers, lakes, channels, reservoirs and so on. It can
also be used for measuring high speed or ultrahigh speed flow rate in pressure pipe of power station
and some scientific experiment.
Parameter setting
The method of modifying K value and measuring time T is the same as above. First, you should press the setting key to shift, and the press the setting number key to set number untill getting the correct number. You can repeat the above operation if you press the wrong key.
3.1.1 In display screen, the symbols between K and C show the signal period delay time:
"0" is the shortest fixed delay (20 B and 1206 B can only use this file)
"1" is 1 second delay;
"2" is 2 seconds delay;
"3" is 3 seconds delay;
"4" is 4 seconds delay;
Note: The tongue reed pipe signal of 20, 12, 10A type is not required to set delay.
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, the famous researching university in China. Much experience has been accumulated from practices so that we can deal with customers' technical problem easily.
