Electronic Universal Pulsar Dn-20 Water Meter

Pulsar DN20 universal electronic water meter

💧 The Pulsar DN20 is an electronic meter designed to measure cold and hot water in private houses, cottages, commercial properties and internal metering systems.

Water flow rotates an internal impeller. An electronic sensor counts its rotations, while the microprocessor calculates the corresponding water volume and displays it digitally.

🌡️ Cold and hot water

• water-temperature range — 0 to +95 °C;
• suitable for cold water;
• suitable for hot water;
• universal version.

📏 DN20 size

• nominal bore — 20 mm;
• permanent flow — 2.5 m³/h;
• installation length — 130 mm;
• connection type — threaded.

📊 Flow rates

• minimum flow — 0.05 m³/h;
• transitional flow — 0.2 m³/h;
• permanent flow — 2.5 m³/h;
• maximum flow — 5 m³/h;
• sensitivity threshold — approximately 0.017 m³/h.

🛡️ Working pressure

Maximum working pressure is 1.6 MPa, or 16 bar.

📡 Pulse and M-Bus versions

The pulse-output version generates electrical pulses for an external controller or modem.

M-Bus is a wired communication interface designed for remote reading of utility meters.

M-Bus is not GSM or mobile internet. A SIM card is not installed inside the meter.

🌐 Internet transmission

Remote internet transmission requires an external controller or modem, power supply, software and receiving server. A SIM card is required only when an external GSM/GPRS modem is used.

💾 Data archive

The electronic module can store hourly, daily and monthly readings in non-volatile memory.

↩️ Reverse-flow detection

The meter can identify reverse water flow and store the event in its internal memory.

🧲 Magnetic-field protection

An integrated sensor detects external magnetic fields. The non-separable body design provides additional protection against unauthorised access.
