Pulse water meter UzMeter-15 HVAC R125 with module

UzMeter DN15 R125 pulse water meter with integrated modem

💧 The UzMeter DN15 R125 with communication module is a mechanical pulse water meter that measures consumption and automatically transmits readings to a remote monitoring system.

It is designed for pipelines with a nominal diameter of DN15 — 15 mm, commonly used in apartments, private houses, offices and small commercial premises.

📡 Meaning of “with module”

In this product, the module is an integrated data-transmission modem. It receives pulse signals from the mechanical meter and sends the accumulated reading to a remote platform.

The main meter and communication equipment are combined in one solution, so a separate external modem is not normally required.

The SIM card is not included and must be purchased separately.

⚙️ Operating principle

Water flow drives the mechanical measuring element. The register records accumulated water volume.

A pulse sensor generates signals after a defined amount of water passes. The integrated modem collects these signals and transmits the reading to the remote system.

📏 Meaning of R125

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

R125 is not a pressure, temperature or maximum-flow rating.

📊 Flow range

• minimum flow — 0.02 m³/h;
• nominal flow — 2.5 m³/h;
• maximum flow — 3.125 m³/h;
• measuring range — 0.02–3.125 m³/h;
• stated sensitivity threshold — 0.032 m³/h.

The stated sensitivity threshold is higher than the listed minimum flow. These values should therefore be verified from the supplied passport.

🌡️ Cold- or hot-water use

The product title specifies cold-water supply, while the Schetchik.uz characteristics also mention hot water.

Before installing the meter in a hot-water line, verify the temperature class and maximum permissible temperature from the nameplate and passport.

📲 Online water metering

The integrated modem enables automatic remote collection of readings.

• collect data without visiting the site;
• monitor water consumption remotely;
• reduce manual transcription errors;
• maintain a consumption history;
• compare different periods;
• detect unusual increases in use;
• integrate the meter with a dispatch platform.

📱 UzMeter mobile application

The UzMeter mobile application is intended for remote monitoring of connected meters. Available functions depend on the modem version, server configuration and user account.

🔩 DN15 threaded connection

The meter is installed using threaded connection parts. Verify the connection thread and face-to-face length before installation.

🛡️ Working pressure

The Schetchik.uz listing specifies a pressure range of 0–1600 kPa. The upper value corresponds to 1.6 MPa or approximately 16 bar.

⚠️ Confirm before ordering

• whether the meter is for cold water only or both cold and hot water;
• temperature class;
• integrated modem model;
• mobile communication standard;
• supported mobile operator;
• module battery type and service life;
• data-transmission interval;
