Since 1825, when the British Klux invented the balanced tank water meter, the development of water meters has nearly 200 years of history, and with the development of modern science and technology and intelligent water services, the types of water meters are becoming more and more diverse, so how many types of water meters are there today, and how should they be divided? The next volumetric water meter supplier will explain the types of water meters for you.
According to the user is usually divided into civil water meter and industrial water meter. The civil water meter only refers to the water meter used for residential water settlement, other uses can be classified as industrial water meters. Industrial water meters are generally large-diameter water meters.
(1) Electronic water meter: a new type of water meter using modern flowmeter-related technology, without mechanical rotation structure. (Electromagnetic water meter, ultrasonic water meter).
(2) Mechanical water meter: often refers to the traditional concept of water meters. It is mainly the application of velocity and volumetric measurement principle, the vast majority of impeller and rotary piston structure.
(3) With electronic device water meter: domestic known as the intelligent water meter. It is a water meter that adds some electronic parts on the basis of the mechanical water meter, which can realize the functions of remote transmission and control.
According to the temperature of the medium can be divided into cold water meter and hot water meter, the water temperature of 30 ℃ is the dividing line.
The lower limit temperature of the medium is 0 ℃, the upper limit temperature of 30 ℃ water meter.
The lower limit temperature of the medium is 30℃, and the upper limit is 90℃ or 130℃ or 180℃ water meter.
Note: When not specified, the general water meter refers to the cold water meter.
Installed in the closed pipe, composed of a moving element, and by the water flow movement speed directly to obtain the power speed of the water meter.
Typical velocity water meters are rotary-wing water meters, screw-wing water meters. The rotor type water meter is divided into a single flow beam water meter and a multi-flow beam water meter.
Installed in the pipeline, by a number of a known volume of the fluid-filled and discharged chamber and by virtue of fluid-driven mechanism composed of the water meter, or simply quantitative discharge water meter.
According to the nominal calibre is usually divided into small-diameter water meter and large-diameter water meter. 50 mm or less water meter is usually called a small-diameter water meter. 50 mm or more water meter is called a large-diameter water meter.
A velocity water meter can be divided into horizontal installation water meter and vertical installation water meter.
According to the installation direction, it is usually divided into horizontally installed water meter and vertically installed water meter (also called vertical meter), which refers to the water meter whose flow direction is parallel or perpendicular to the horizontal surface when it is installed, and "H" represents horizontal installation and "V" represents vertical installation on the scale of the water meter.
The volumetric water meter can be installed in any position without affecting the accuracy.
