1/2 Inch Water Meter

1/2 Inch Water Meter

A 1/2″ water meter, corresponding to a nominal diameter of 15mm (DN15), is a very common size, primarily found in individual residential units and apartment units. It is designed for applications with lower flow rate requirements, offering reliable and accurate water consumption measurement where demand is moderate.

1/2″ Water Meter Flow Rate

According to ISO 4064, for a 1/2″ water meter with an R160 accuracy class, typical flow rate parameters are as follows:

• 1/2″ Water Meter Minimum Flow Rate (Q1): 15.6 L/h

• 1/2″ Water Meter Transitional Flow Rate (Q2): 25 L/h

• 1/2″ Water Meter Permanent Flow Rate (Q3): 2.5 m³/h

• 1/2″Water Meter Overload Flow Rate (Q4): 3.125 m³/h

1/2″ Water Meter Installation

The installation orientation of a 1/2″ water meter is a key factor influencing its measurement accuracy, and this sensitivity varies based on the meter’s design. For horizontal-type water meters, installing the meter in a horizontal position generally yields the highest accuracy, typically outperforming a vertical installation for the same meter model.

• 1/2″ Water Meter Horizontal Installation Accuracy: R160

• 1/2″ Water Meter Vertical Installation Accuracy: R80

1/2″ Water Meter with Fittings

The quality and type of water meter fittings are essential for maintaining water quality and ensuring a secure, leak-free connection. For example, BMAG’s 1/2-inch water meters are provided with high-quality brass fittings and integrate a plastic check valve core. This built-in check valve core effectively prevents any backflow of water, safeguarding the water supply system and helping to maintain the precision of the water meter’s measurements.
