Inline Gas Density Meter

This MEMS-based sensor measures gas density in gas lines or storage tanks using a tuning fork oscillator. The natural frequency varies with gas density, while integrated components monitor pressure and temperature. Compact (33 mm diameter, 63 mm length), it’s easy to install and comes with a filter to prevent contamination. Data is transmitted via RS485, and the sensor provides real-time measurements with a 5-second response time for stable results.
