SARF GPRS G4 ultrasonic gas meter with modem and shut-off valve

🔥 The SARF GPRS G4 is an electronic natural-gas meter designed for apartments, cottages, small houses and commercial properties.

It measures gas flow ultrasonically, stores readings electronically and transmits them over an integrated GSM/GPRS modem to a compatible gas AMR system.

🏠 Designed for smaller installations

The G4 model is generally suitable for one or two gas-consuming appliances:

• a gas cooker;
• a cooker and water heater;
• small heating equipment after flow calculation;
• a small commercial property.

Final selection must be based on the combined maximum consumption of all connected appliances.

📡 GSM/GPRS communication

The integrated modem sends readings over a mobile network to a compatible utility or AMR server.

A prepaid SIM card is stated as included.

Confirm the mobile operator, prepaid period and future service charges before purchase.

🔒 Integrated shut-off valve

The valve may stop gas supply in response to debt, reverse flow, a diagnostic fault or an authorised remote command.

The user must not open, modify or repair the meter or valve.

📏 DN25 threaded connection

The standard horizontal SARF G4 listing states a 25 mm connection.

A separate vertical SARF G4 version has a different design and a 15 mm connection. Confirm the required configuration before ordering.
