Pulse water meter SWEM Dn-25
SWEM DN25 mechanical pulse cold-water meter
💧 The SWEM DN25 is a mechanical water meter with a pulse output, designed to measure cold-water volume in pipelines with a nominal diameter of DN25 — 25 mm.
It combines conventional local metering with automated data-collection capability. Readings can be viewed directly on the register or transmitted through the pulse output to a modem, controller or dispatch system.
⚙️ Mechanical measuring principle
Water flow drives the measuring mechanism inside the body. Its movement is transferred to the roller register, which displays accumulated water volume in cubic metres.
No external power supply is required for local reading.
📊 Pulse-output operation
After a defined volume of water passes, the sensor generates an electrical pulse. The supplied cable can transmit these signals to:
- a SWEM data-transmission modem;
- a controller;
- a pulse counter;
- a data logger;
- a dispatch system;
- an automated water-metering platform.
Important: the pulse output is not an integrated GSM modem. A separate communication device is required for cellular transmission.
📈 Flow range
- minimum flow — 0.07875 m³/h;
- nominal flow — 6.3 m³/h;
- maximum flow — 7.875 m³/h;
- sensitivity threshold — 0.0267 m³/h;
- stated error — 2%.
🌡️ Cold-water application
According to the Schetchik.uz listing, this model is intended for cold-water metering. The stated operating-temperature range is 5 to 50 °C.
Do not install it in a hot-water system unless such use is explicitly permitted by the supplied passport.
🔩 DN25 threaded connection
The meter is installed using threaded connection parts. Unions and sealing gaskets are included in the package.
Before installation, verify the thread size, flow direction and available space for the 265 mm body length.
🛡️ IP68 protection
The product listing specifies an IP68 protection rating, indicating dust-tight construction and water protection under manufacturer-defined conditions.
Protection at depths up to 35 m is also stated, but the permitted depth, duration and cable-sealing requirements must be verified from the passport.
📡 Remote metering capability
For automatic reading transmission, use a separate SWEM modem or the ready-made SWEM DN25 meter and modem kit.
- collect readings without visiting the site;
- monitor consumption remotely;
- reduce manual-entry errors;
- create consumption archives;
- compare different reporting periods;
- integrate with automated metering systems.
The modem and SIM card are not included in the standard package.

- avoid misalignment and mechanical stress;
- keep the meter completely filled with water;
- protect the pulse cable against damage;
- do not route the signal cable next to power cables;
- check all joints for leakage;
- compare local and remote readings after commissioning.
⚠️ Confirm before ordering

- pulse-sensor type;
- supplied cable length;
- maximum permissible working pressure;
- accuracy class;
- conditions applicable to IP68;
- compatibility with the selected modem;
- manufacturing date;
- country of origin of the supplied batch;
- exact package contents.
