Rotor water meter is suitable for measuring the total amount of unidirectional water flow in small diameter pipes. Such as with a caliber of 15mm, 20mm specifications of the pipeline household water consumption measurement. This kind of water meter is mainly composed of shell, impeller measuring mechanism and deceleration mechanism, as well as indication table, and is characterized by simple structure. There are many kinds of meters, including Mechanical ones without output. With signal output, with signal output is mostly analog output, but there are also patented technology back-end digital style. In addition, there are many kinds of rotary-wing water meters Measuring principle, for example, the water flow drives the rotary wing Drive the gears to count, there are also rotary wing every turn to output a pulse signal, the back of the circuit to count. The working principle of rotary wing type single beam water meter is: the water flow from the case inlet tangentially impacts the impeller to make it rotate, and then through the gear deceleration mechanism to continuously record the number of revolutions of the impeller, so as to record the cumulative flow rate through the water meter.
