Gidro Dn-20 mechanical Water meter

Gidro DN20 mechanical water meter

💧 The Gidro DN20 is a mechanical meter designed to measure cold and hot water passing through a pipeline with a nominal diameter of 20 mm.

It is suitable for internal metering in private houses, cottages, shops, offices and small utility properties.

⚙️ Mechanical operation

Water flow drives the measuring mechanism, and accumulated consumption is displayed on a mechanical roller register.

The meter requires no mains electricity, battery, SIM card or internet connection.

📏 Meaning of DN20

DN20 indicates a nominal pipeline diameter of 20 mm.

This size is commonly used for water inlets serving private houses, cottages and small commercial properties.

🌡️ Cold- and hot-water use

The Schetchik.uz listing identifies the model as universal for cold- and hot-water metering.

The exact temperature range must be verified from the product passport and nameplate.

📵 No remote data transmission

The Gidro DN20 is a conventional mechanical meter. No remote-reading output or integrated modem is stated.

Automated metering requires a pulse-output, RS-485 or modem-equipped model.
