Working Principle:
The module utilizes bidirectional calorimetric measurement technology. It detects the heat transfer caused by the movement of gas molecules across a heated sensing element. By analyzing the thermal differential, the module calculates the mass flow rate with high precision. The integrated microprocessor linearizes the raw thermal data and outputs the calibrated flow value via analog voltage/current or I2C digital signals.
Installation Requirements:
- Space Allocation: Ensure a minimum clearance of 50 x 40 x 20 mm within the device enclosure for proper fitment.
- Gas Connections: Connect to the gas manifold or analyzer using appropriate low-dead-volume tubing to maintain response time.
- Electrical Wiring: Properly terminate the analog or I2C connections. Configure the two address pins according to the system’s I2C bus topology if using digital output.
- Orientation: Follow manufacturer guidelines for sensor orientation to prevent particulate accumulation on the sensing element.
Usage Precautions:
- Gas Compatibility: Verify that the gas being measured is compatible with the internal calorimetric sensor materials to prevent corrosion or degradation.
- Cleanliness: Ensure the gas supply is properly filtered to prevent dust or moisture from contaminating the sensitive thermal sensing element.
- Thermal Stability: Avoid sudden ambient temperature fluctuations that could affect the calorimetric baseline.
- Handling: Handle the module with care during installation to avoid mechanical shock to the internal micro-sensors.
