Hot Water Meter

Hot Water Meter is a high precision multi dry type measuring device designed for accurate consumption tracking in hot water distribution systems. The meter operates with a magnetic transmission system ensuring that the register remains completely isolated from water, preventing condensation and contamination.

The body is manufactured from corrosion resistant brass and coated with electrostatic paint for extended service life. The internal mechanism features a 5 drum register for reliable reading, supported by impact resistant glass for long term durability under pressure and temperature fluctuations.

With low pressure loss and stable metering performance, this hot water meter is suitable for residential, commercial, and municipal applications. The 360° rotating lid allows flexible installation and easy reading from different angles.

Designed for hot water applications up to 90°C, the product ensures long maintenance free operation with optional pulse output for remote monitoring systems.
