ProSight Micro Thermal Mass Flow Meter 420mA RS485 24 V DC

ProSight Micro Thermal Mass Flow Meter 420mA RS485 24 V DC is a compact and highly sensitive flow measurement instrument designed specifically for measuring the mass flow of gases such as air, nitrogen, oxygen, carbon dioxide, argon, and other non-corrosive gases. Unlike traditional volumetric flow meters, it directly measures mass flow, providing more accurate and reliable results across varying operating conditions.

How Does It Work?

The flow meter operates using MEMS (Micro-Electro-Mechanical Systems) thermal mass sensing technology. Inside the sensor are precision micro-heaters and temperature sensors. As gas flows through the sensing element, it removes heat from the heated sensor. The amount of heat carried away is directly proportional to the gas mass flow rate. The electronics continuously monitor this heat transfer and convert it into an accurate flow measurement. Because the measurement is based on mass flow rather than volume, pressure and temperature compensation are typically unnecessary.

Why Choose This Product?

This micro thermal mass flow meter offers a highly efficient solution for applications requiring accurate low-flow gas measurement. Its compact size, exceptional sensitivity, and digital output options make it suitable for OEM integration and industrial automation systems.
