## Long description

B\_METERS GSD8-I is a mechanical hot water meter designed for accurate measurement in domestic and light commercial installations. The meter features a 3/4" AC threaded connection and a nominal flow rate Q3 of 4.0 m3/h. Constructed for hot water service, it supports media temperatures up to 90°C and has an overall length of 130 mm. The device is MID-approved with R100/R50 accuracy classes and includes anti-magnetic protection to reduce the risk of tampering from external magnetic fields.
Advantages
The meter combines a compact 130 mm body with a relatively high nominal flow capacity, allowing installation in confined spaces while supporting flow peaks. MID approval ensures compliance with legal metrology requirements for billing and official measurement. Anti-magnetic protection increases measurement integrity in environments where external magnetic influence is possible. The mechanical register provides a straightforward, battery-free indication of consumption and is suitable for installations where electrical power is not available or desired.
Suitable for
 Residential hot water metering and billing
 Small commercial properties such as offices, shops, or guest houses
 Replacement of existing inline meters with a 3/4" connection and 130 mm length
 Applications requiring MID-approved metering with anti-magnetic protection

How to use
Install the water meter in a horizontal or vertical pipeline segment according to local regulations and industry practice, ensuring flow direction matches the arrow on the meter body. Use compatible 3/4" AC fittings and appropriate sealing material to prevent leaks. Ensure the installation location can withstand the rated maximum water temperature of 90°C and provide access for reading the mechanical register. After installation, verify there are no leaks and perform a functional check by running water through the meter and confirming register movement.
Usage recommendations
For accurate and long-term performance, install the meter where it is protected from freezing and direct sunlight, and where magnetic interference is minimized despite the anti-magnetic features. Follow local metrology and installation standards for calibration intervals and sealing procedures. Regular visual inspections and occasional flushing of the line to remove debris will help maintain measurement accuracy.
