Water meter B_METERS GSD8-I for hot water, 1/2" AC, Q3 2.5 m3/h, Tmax 90°C, L 110 mm, anti-magnetic, MID R100/R50 AM

Inline hot water meter B_METERS GSD8-I is designed to measure hot water consumption in residential and light commercial installations. The meter features anti-magnetic protection and a compact 110 mm installation length for use in tight plumbing spaces. With a nominal connection of 1/2" AC and a flow class Q3 = 2.5 m3/h, this device supports accurate volumetric measurement at temperatures up to 90°C. The meter is MID-certified (R100/R50 AM) to ensure legal-for-trade accuracy and reliable billing.

Advantages

The B_METERS GSD8-I combines a short overall length with anti-magnetic protection to reduce the risk of tampering and maintain measurement integrity. Its high maximum temperature rating up to 90°C allows installation on hot water lines and near boilers. The meter’s Q3 = 2.5 m3/h flow capacity covers typical residential demands while providing stable readings across the specified flow range. MID certification guarantees compliance with regulatory accuracy requirements for billing purposes.

Suitable for

• Measuring hot water consumption in apartments and multi-family buildings
• Use on domestic hot water lines connected to boilers and water heaters
• Replacement of existing inline meters where 110 mm installation length is required
• Applications requiring tamper-resistant measurement with anti-magnetic protection

Key specifications

• Nominal connection: 1/2" AC
• Flow class: Q3 = 2.5 m3/h
• Maximum operating temperature: 90°C
• Installation length: 110 mm
• Anti-magnetic protection to limit tampering via external magnetic fields
• Mid-accuracy range certified for legal-for-trade consumption measurement

How to use

Install the B_METERS GSD8-I inline in the hot water supply pipe using compatible 1/2" AC fittings and ensure correct flow direction indicated on the meter body. Position the meter in an accessible location for reading and maintenance, while avoiding direct exposure to freezing conditions. After installation, flush the line to remove debris and verify that the meter registers flow. Periodically check the register and inspect the meter housing for physical damage or signs of tampering.

Usage recommendations

For reliable long-term performance, install the meter where operating temperatures do not exceed 90°C and where hydraulic conditions match the meter’s flow range. Ensure fittings and sealing materials are compatible with hot water service. If remote reading or integration with building management is required, select compatible interfaces or remote modules offered by the installer or manufacturer.
