Introduction of rotary water meter
Rotary water meter: Rotary water meter is suitable for measuring the total amount of one-way water flow in small-diameter pipes. For example, domestic water consumption is measured by pipes with diameters of 15mm and 20 mm This kind of water meter is mainly composed of shell, impeller metering mechanism, deceleration mechanism and indicator, and has the characteristics of simple structure.
Rotor water meter is suitable for measuring the total amount of unidirectional water flow in small diameter pipes. For example, domestic water consumption is measured by pipes with diameters of 15mm and 20 mm This kind of water meter is mainly composed of shell, impeller metering mechanism, deceleration mechanism and indicator, and has the characteristics of simple structure.
There are many kinds, including machinery without output. With signal output, mostly analog output, but there are also patented back-end digital models. In addition, there are many measuring principles of rotary water meter. For example, the water flow drives the rotor to drive the gear to count, and the rotor outputs 1 pulse signal every revolution, and the following circuit counts. The working principle of rotary-wing single water meter is that water impacts the impeller tangentially from the water inlet of the watch case to make it rotate, and then the number of revolutions of the impeller is continuously recorded through the gear reduction mechanism, thus recording the cumulative flow through the water meter.
The working principle of rotary-wing multi-flow water meter is basically the same as that of single-flow water meter. Through the shunt action of the impeller box, multiple streams of water impact the impeller tangentially from the water inlet of the impeller box, which balances the axial impact of water on the impeller, reduces the wear of the impeller support, structurally reduces the influence of the installation and scaling of the water meter on the error of the water meter, and the overall performance is obviously higher than that of a single-stream water meter.
Second, the price of rotary water meter
1, Zhejiang Yueqing "Spring Tide" common rotary water meter, vertical water meter, DN 15 anti-drip water meter.
28.90? Yuan dynasty (1206- 1368)
2. Changde brand LXS-32E rotary-wing digital cold water meter rotary-wing e water meter
45 yuan
3. Shandong water meter manufacturers sell copper-clad horizontal smart water meters.
2 15.00? Yuan dynasty (1206- 1368)
3. What are the specifications of household water meters?
Caliber: 15mm, 20mm, 25mm? These are ordinary household water meters.
The diameter is the diameter of the inlet and outlet of the water meter. Water meters are divided into two kinds of movements: rotor and spiral wing. The general household water meter with 15mm rotor has low cost and convenient maintenance. Now there is a plug-in water meter, which saves money and then uses water. In some areas, the tap water business hall has this kind of business.
The above contents are information such as the price and introduction of rotary-wing water meter. For friends who are interested in buying and using related similar products, it is particularly necessary to study in advance. And correspondingly, considering that bad consumers can't choose the right one in terms of size and corresponding classification when they actually choose many products on the market, we finally present practical information to facilitate everyone's purchase and ensure the excellent effect in the later period as much as possible.
