Primaflow Water Meter - 1/2" Class B R80 - SJ-SDC Dn15

'Class B' refers to the accuracy class of the meter according to international standards, indicating a specific tolerance for measurement error. 'R80' typically denotes the minimum flow rate at which the meter can accurately measure, expressed in liters per hour.

This Primaflow meter is designated as a 'secondary meter'. It is generally intended for sub-metering specific zones or appliances within a property. For main water service, you would typically need a primary meter approved by your local water authority.

While specific temperature limits depend on the exact model variant, residential water meters like this are typically designed for cold water applications and may not be suitable for hot water lines. Avoid prolonged exposure to extreme temperatures.

It is recommended to visually inspect the meter monthly for any signs of leaks or damage. For accuracy verification, compare readings with overall household consumption over a period.

No, this is a mechanical water meter and does not require any external power source to function.

Standard plumbing tools such as pipe wrenches, thread sealant (tape or paste), and possibly pipe cutters or adapters depending on your existing plumbing configuration.

Ensure the water supply is on and flowing through the meter in the correct direction. Check for any blockages before or after the meter. Verify the installation is secure and there are no leaks.

Confirm the meter is installed in the correct orientation (arrow indicating flow direction). Check for vibrations or external factors that might affect the meter's components. Ensure there are no leaks downstream that could cause continuous, unrecorded flow.

Turn off the water supply and re-tighten the connections. Ensure appropriate thread sealant or tape was used during installation. Inspect the fittings and the meter's connection points for any damage.
