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.
Tired of Surprises on Your Water Bill? Meet Your New Best Friend: The Rotary Vane Water Meter!
Ever wonder exactly how much water your household is using each month? If your water bills feel a bit unpredictable, it might be time to get a clear picture with a reliable rotary vane water meter.
Think of it as your home's personal water accountant. This type of mechanical water meter uses a simple but smart design-water flows through, spinning a small internal vane or paddle. Each rotation is counted, translating directly into accurate water usage data. No guesswork, no complex electronics-just straightforward, dependable measurement.
One of the biggest perks? Durability. Made with minimal moving parts, these meters are built to last, offering years of service with little to no maintenance. They're the go-to choice for residential water measurement in homes and apartment buildings worldwide.
By giving you a clear view of your consumption, a rotary vane water meter helps you become more water-conscious. Spotting unusual usage patterns early can help you detect leaks, save money, and contribute to water conservation-all while keeping your bills transparent.
If you're looking for a cost-effective and high-accuracy water meter for your home or building project, this trusted mechanical workhorse is definitely worth considering. Know your flow, take control of your usage, and never overpay again!
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.
