The GasMeter from Garten was developed to monitor the cellular respiration of grains stored in silos by continuously measuring CO2 concentration, the most sensitive indicator of the product’s metabolic activity. Since increases in respiration occur well before any rise in temperature, the system detects anomalies up to five weeks earlier than conventional thermometry methods, enabling essential preventive actions to preserve grain quality.
The device uses non-dispersive infrared CO2 sensors, ensuring precision and stability in readings. Each silo is equipped with a dedicated sensor capable of monitoring the entire stored mass without the coverage limitations typical of thermal sensors. GasMeter integrates directly with the STARK thermometry system, which records the full history of measurements for analysis, trend evaluation, and decision-making.
Data access is remote and in real time, viewable through notebooks, tablets, or smartphones. This allows operators to track grain behavior and adjust automatic aeration to maintain ideal storage conditions, reducing losses caused by insects, fungi, or deterioration. Its control panel operates on 110/220 VAC and uses industrial communication through Modbus TCP and Modbus RTU RS485, ensuring complete integration with automation systems.
With its early-detection capability, GasMeter enhances storage performance, increases operational safety, and contributes directly to process profitability—making it an essential solution for those seeking rigorous control and preservation of grain quality.
