Prepaid Gas Meter

A self-contained prepaid gas meter with its own keypad and screen — the customer tops up by entering a code (STS token) directly on the unit, with no separate display needed.

Why clients choose it

• Tops up on the meter itself using a secure STS numeric code — simple for customers, no app required.
• Rugged aluminium die-cast case built for indoor or outdoor installation.
• 9-digit backlit LCD display shows the remaining balance clearly, day or night.
• Double reed-switch sensing detects magnetic tampering and protects against fraud.
• Battery life of 5+ years keeps maintenance visits to a minimum.
• Certified to international metering (OIML) and prepayment (STS/IEC 62055) standards.
