Product Use
The meter is used to measure the total amount of drinking water flowing through a tap water pipe. It is only suitable for clean water that flows in one directio.
Structural Characteristics And Working Principle
After the water flows into the water meter, it enters the measuring mechanism through the lower inlet holes of the impeller housing, driving the rotation of the impeller. The water then exits through the upper outlet holes of the impeller housing. The speed of the impeller is directly proportional to the flow rate of the water. The rotation of the impeller is transmitted via a reduction gear to the indicator mechanism, which records the total amount of water that has flowed through the meter. The counter of this water meter is immersed in the measured water, known as a rotary-wing wet-type water meter. The basic unit of measurement for this water meter is M3.
The components are made of high quality materials and corrosion resistant treatment, with the advantages of accurate measurement, durable and convenient maintenance.
