MAF Sensor on Flowbench

With the help of several people to gather the correct components and guide me in wiring up things properly I’ve been able to add the ability to measure the voltage reported by the MAF sensor when the MAF housing is attached to the flow bench.

Hitachi Maf Sensor on PTS FlowbenchDuring the first check out of the setup, when I finally began getting readings on the multi-meter, I noticed that the voltage reported from the sensor is not very steady, except for when the airflow is zero.  I’ll be thinking about how to minimize the affect of the variation since it appears that the voltage swing is greater than what the bench is reporting as variation in the airflow.
