How are flow meters for compressed air measurement?
Manage your compressed air system with meters that: Measure mass flow directly, so no temperature or pressure compensation is required. Have a very high turndown, allowing the same flow meter to measure very low leak rates as well as full operational flows. Operate over a wide range of temperatures and pressures.
How is the mass air flow sensor tested?
How the mass air flow sensor is tested. In modern cars, the only way to test the mass air flow sensor is with a scan tool. Mechanics measure the amount of air flow (mass air flow sensor readings) at different RPMs. They compare the readings to the specifications or to the readings of a known-good mass airflow sensor.
Where can I find the trouble code on my air flow sensor?
When the air flow sensor signal varies from the expected range, the PCM records a fault and stores the corresponding trouble code, illuminating the Check Engine light on the dash. This trouble code can be retrieved with a scan tool. The following trouble codes are usually associated with a mass air flow sensor:
Which is the best way to measure air compressor discharge?
Based on the comparison, a pitot tube flow sensor stands out as the best choice for measurements at the compressor discharge. This method has proved its robustness in industrial applications. It is also the standard method for measuring air speed in the aircraft industry.

What does the light on the engine management light mean?
This measures the amount of unburnt oxygen passing through the exhaust of the car, which can indicate whether the engine is burning too much or too little fuel. If too little oxygen leaves the exhaust, the engine will be running ‘rich’ – taking too much fuel and not enough air into its cylinders.
What to do if your engine management light is amber?
In the majority of cases, the car will need to be connected to diagnostic equipment to determine exactly where the fault lies. In many cases, the light operates on a colour-coded basis. An amber EML doesn’t necessarily point to an unfolding emergency – you should be able to continue on your way and seek advice on reaching your destination.
