Water meter B_METERS GSD8-RFM for hot water 1/2" AC Q3 1.6 m3/h DN15 Mid R100/R50

B_METERS GSD8-RFM is a mechanical hot water meter with integrated radio module designed for residential use. It features a 1/2" (DN15) connection and an AC flow direction configuration, with a nominal Q3 flow rate of 1.6 m3/h. The meter is built to record domestic hot water consumption with Mid accuracy class and a metrological range of R100/R50, enabling reliable measurement across typical household flow rates. The integrated radio module enables remote reading and reduces the need for manual meter reading visits.

Advantages

The meter combines mechanical measurement reliability with radio communication capability for automated data collection. Its compact DN15 form factor and 1/2" connections make it compatible with common residential plumbing. The Mid accuracy class and R100/R50 range provide a balance between measurement precision and wide operational range suitable for apartment and single-family installations. The radio module supports efficient remote reading, improving billing accuracy and reducing onsite access requirements.

Suitable for

• Measuring hot water consumption in apartments and single-family homes
• Residential buildings where remote meter reading is required
• Replacement of existing 1/2" hot water meters with AC flow orientation
• Properties with standard domestic hot water flow ranges

How to use

Install the meter in the hot water supply line with the correct orientation for AC flow as indicated on the device. Connect using standard 1/2" plumbing fittings and ensure seals and gaskets are properly seated to prevent leaks. After mechanical installation, verify the radio module is powered and configured according to the remote reading system requirements. Record initial meter reading and register the device in the building’s consumption monitoring system where applicable. Periodically inspect connections and check for any signs of wear or leakage.

Usage recommendations

For accurate readings and long-term reliability, install the meter in an accessible location free from excessive vibration, freezing risk, or direct exposure to sunlight. Follow local regulations for hot water metering and scheduling of periodic verification or calibration where required.
