⛽ Magnetostrictive Level Sensor for ATG Systems

Accurate fuel inventory management is essential for modern gas stations and fuel storage facilities. An Automatic Tank Gauge (ATG) system provides real-time monitoring of fuel level, water level, temperature, and inventory changes — helping operators improve efficiency and prevent fuel losses.

With high accuracy, excellent repeatability, and long-term stability, magnetostrictive level sensors can help:
✅ Monitor fuel level and water interface inside underground storage tanks
✅ Detect abnormal fuel loss caused by leakage or theft
✅ Provide real-time inventory data for fuel management systems
✅ Support remote monitoring and automatic tank management

🔹 Applications:

• Underground Storage Tanks (UST)

• Automatic Tank Gauge (ATG) Systems

• Fuel Inventory Monitoring

• Gas Station Fuel Management

• Oil & Chemical Storage Tanks

☀️ Holykell PT100 temperature sensors used for Solar Mat Heating Systems.
A PT100 sensor itself is a passive resistance element. It does not generate a digital signal or communication output such as RS485. Its resistance changes according to temperature, and therefore a signal conversion module is needed to signal transmission.

We specially developed a custom acquisition module for the customer, which integrates signal conditioning and data transmission functions. This allows the PT100 sensor system to directly communicate with industrial controllers or PLC systems.
