Mechanical hot and cold water meter SWEM Dn-15 (R125)

SWEM DN15 R125 mechanical hot- and cold-water meter

💧 The SWEM DN15 R125 is a universal mechanical meter for measuring hot- and cold-water consumption in pipelines with a nominal diameter of DN15 — 15 mm.

It is suitable for apartments, private houses, cottages, small commercial premises and internal metering points. The meter operates without an external power supply.

⚙️ Mechanical impeller principle

Water flow rotates an impeller inside the measuring chamber. Its movement is transferred to the roller register, which displays accumulated water volume in cubic metres.

🌡️ Hot- and cold-water application

• cold-water supply;
• hot-water supply;
• internal process metering;
• commercial water metering.

Verify the temperature marking of the supplied batch from the nameplate and passport before installation.

📏 What R125 means

R125 describes the meter’s measuring-range ratio. In practical terms, it indicates that the meter is designed to register both normal consumption and relatively low water flow.

R125 is not the maximum flow, pressure or water temperature.

📊 Pulse output

The meter can generate electrical pulses after a defined volume of water passes. The signal can be transmitted through the supplied cable to a modem, controller or automated metering system.

The pulse output is not an integrated GSM modem. A separate communication device is required for cellular data transmission.

📡 Remote metering

For automatic reading transmission, consider the ready-made SWEM DN15 meter and modem kit.

• collect readings without visiting the site;
• reduce manual transcription errors;
• create consumption archives;
• monitor changes in water usage;
• integrate with automated metering systems.

🔩 Threaded connection

The meter is installed using threaded connection parts. Unions and sealing gaskets are included in the package.

🛡️ IP68 protection

The product listing specifies IP68, indicating dust-tight construction and water protection under conditions defined by the manufacturer.
