Product Introduction
The gas pressure regulator early warning system consists of an information acquisition unit (gas pressure regulator early warning device), a communication hub (telecom base station), information terminals (PCs and mobile devices), and an alarm server. The information acquisition unit collects on-site data from the gas pressure regulator and directly transmits it via the early warning device to a designated host. Through a dedicated server and monitoring terminals (PCs and mobile devices), real-time remote monitoring of the gas pressure regulator’s operational status is achieved. Pressure and alarm data can be viewed directly on the device’s screen.
By pairing with different transmitters, the system can monitor data such as pressure, differential pressure, gas leakage concentration, internal pipeline temperature, flow rate, shut-off valve operational status, and the open/close status of the pressure regulator cabinet door.

Technical Features
1. Customizable power supply solutions: Offers mains power, battery, and solar power options based on customer requirements.
2. Unlike large-scale SCADA systems, this system is easy to install, does not require mains power, is cost-effective, and supports multiple communication methods: GPRS, NB-IoT, and 4G.
3. Automatically collects data and generates data charts, facilitating data storage while reducing paper consumption—eco-friendly and energy-saving.
4. Enables proactive risk prevention through real-time alarms, extending the service life of pressure regulators and reducing gas usage risks.
5. High efficiency and low maintenance costs help reduce enterprise expenditures, delivering both economic and social benefits.
6. Ensures safe gas usage for end-users and enhances service quality and management standards in the gas industry.
7. The monitoring equipment records and tracks data including pressure, leakage, flow rate, differential pressure, temperature, and shut-off status, enabling comprehensive, full-lifecycle monitoring of pressure regulator equipment.
