Mass Air Flow sensor in hydrogen fuel cell
Rainbow's Mass flow sensor for use in Hydrogen fuel cell control system, measure the air going into the fuel cell.
In the context of fuel cells, Mass Airflow Sensors are devices used to measure the mass flow rate of air entering the fuel cell. Fuel cells require a precise balance of reactants, including the right amount of air for the electrochemical reaction that generates electricity.

1. Customizable range between 10SLM and 500SLM
2. SLM: Standard liters per minute. Standard conditions: 0 ° C and 1 atmosphere
3. In addition, the two-way airflow test can be customized, and the analog output is correspondingly changed. F(min)—F(max) corresponds to 1-5V output, and 0 flow corresponds to 3V;
4. Includes temperature drift and linearity error
