Dry-type Rotary Vane Water Meter

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.

Let's be honest, have you ever tried to read a water meter only to find the glass is cloudy, there's condensation inside, or even worse-you can't see the numbers at all? This is a common headache with older meters, but it's a problem that the dry-type rotary vane water meter is specifically designed to solve.

The key difference is right in the name: the "dry-type" design. Unlike traditional meters where the counting mechanism sits in water, this meter uses a clever magnetic drive system. The spinning vane that measures the water flow is completely separated from the register dial (the part with all the numbers). It's like having a sealed, watertight barrier between the wet stuff and the brains of the operation.

So, what does this mean for you?

Crystal-Clear Readings, Always: No more foggy glass or algae growth obscuring the numbers. The register stays perfectly dry and legible, making manual readings a breeze and eliminating guesswork.

Excellent Cold Weather Performance: The dry chamber is much less prone to freezing and cracking in cold climates, making it a reliable water meter for seasonal or colder regions.

Less Maintenance, More Peace of Mind: With no water in the register, there's far less risk of internal corrosion or mineral buildup, which translates to a longer service life and reduced maintenance costs.

For homeowners and utilities looking for a durable and accurate water meter that delivers hassle-free performance, the dry-type rotary vane meter is a brilliant, modern choice. It's all about getting a clear, dependable measurement without the usual mess.

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.
