Volumetric Water Meter
A piston water meter is a device used to measure the flow of water through a pipeline by utilizing the movement of a piston within a chamber. Its accurate and reliable performance makes it a widely used device for monitoring water usage and managing water resources.
BMAG Meter’s volumetric water meters (piston type) are designed for high-precision residential metering. Unlike standard meters, our rotary piston technology ensures accurate measurement even at extremely low flow rates, meeting ISO 4064 Class C (R160/R200/R400) standards.

Volumetric Water Meter FAQ
A volumetric water meter is a water meter installed in a closed pipe, also known as a rotary piston water meter.
The main features of a volumetric water meter include high accuracy and stability, and are suitable for water metering in a wide range of flow rates.
In addition, this water flow meter is widely used in domestic water supply networks, providing accurate water consumption measurement, helping to detect leaks, and ensuring measurement accuracy in different installation locations.
The working principle of volumetric water meter is to measure the volume of water flowing through the pipe by means of some known volume metering chambers that are successively filled and discharged with fluid and a mechanism driven by the fluid.
This water flow meter uses mechanical principles to separate the fluid into individual parts and count these parts, so it is also called positive displacement water meter or simple displacement water meter.
Volumetric water meter can promote the rational use and protection of water resources by accurately measuring and managing water volume.
Some of the main applications of volumetric water meter are: household water management, industrial and commercial water management, remote automatic reading system, hydrological survey and water resource monitoring, municipal water supply and drainage monitoring, water supply enterprise operation, environmental protection and water treatment, etc.
The main types of materials used for volumetric water meters are copper and plastic.
The copper water meter case has superior mechanical properties and can withstand large external forces without being easily deformed or damaged.
When plastic is used to make the shell of the cold water pipe meter, it has the characteristics of being durable and corrosion-resistant.
