What is an STS Gas Meter?
I. Introduction to STS Gas Meters
The STS prepaid gas meter is a prepaid gas meter solution that complies with the STS protocol. Users can recharge the meter and query parameters by entering a 20-digit recharge code or a 2-digit query code through the touch buttons integrated on the meter. In addition, the meter has a reserved infrared communication method, and users can also use an infrared remote control to input recharge/query codes, which is suitable for users whose meter installation locations are relatively concealed and inconvenient to access.
II. Functional Features of STS Gas Meters:
1. Compatible with the South African STS prepaid protocol, supports TOKEN code command reception, and meets compliance application requirements.
2. Equipped with a LoRaWAN wireless communication module, it supports wireless meter reading. When using a CIU or handheld device for meter reading, the communication distance can reach up to 350m; when using a concentrator, the communication distance between the concentrator and the gas meter can reach 1000m.
3. The gas meter has an internal high-capacity 3.6V lithium battery with integrated low-power programming, which can last for approximately 5 years under normal use.
4. It can switch between two different modes: prepaid mode and postpaid mode.
5. It has an automatic valve shut-off error message function for unauthorized battery removal, and also has a magnetic interference metering error message to prevent magnetic interference, meeting basic user needs.
6. The electronic module and the entire meter adopt a fully sealed design with an IP65 protection rating, providing complete dustproof and strong waterproof capabilities.
III. Application Scenarios of STS Gas Meters
Widely applicable to residential, small commercial, and remote areas with weak network coverage. Some models can be connected to leak sensors to automatically close valves, adapting to smart home and smart community security systems.
