The function of an air flow meter on a fuel injected engine is to check the quality or quantity of air. It sends a signal to the ECM or Electronic Computer Module and in turn, the ECM decides whether to send more fuel to the engine or not.
An air flow meter measures the amount of air entering an engine to help determine the appropriate fuel-to-air ratio for combustion. This helps optimize engine performance and fuel efficiency by ensuring the correct amount of fuel is injected based on the amount of air being drawn into the engine.
It operates only when the engine is turned over due to vacuum/suction from the engine .....If not working properly, there will be no electrical charge to the injectors.
Another name for a peak flow meter is a peak expiratory flow meter (PEFM). This device is used to measure the maximum speed of expiration, helping to monitor lung function, especially in individuals with asthma or other respiratory conditions.
From my experience and basic knowledge of owning a 1.8 and 2.2 engine, i believe i carries a MAF Sensor...The 2.2 carries an air flow meter...
the mass air flow sensor detects the flowing of mass air into the engine while the mass air flow meter detects the amount of mass air flowing into the ingine.
THE SYMBOL FOR Flow Meter is : FI as Flow Indicator
The above is the symbol of flow meter.
One can recalibrate a flow meter by having a company or owning a flow meter supplier or using a flow meter lab. No matter what type of flow meter they need to be checked to see if they need to be recalibrated regularly.
ANY METER needs some kind of current flow to operate. Internal in the meter there are batteries that provide current that when passed trough a resistor will develop voltage as a function of the current. the meter will read this current and display the resistor size to cause this current to flow.
The flow range of a gas flow meter is the range of flow rates that the meter is capable of measuring accurately. It typically includes a minimum and maximum flow rate that the meter can reliably detect and measure. It is important to ensure that the flow rates being measured fall within the specified flow range of the gas flow meter for accurate readings.
rota meter
I believe it depends on what kind of flow meter you are looking for. They can range from 19.99 and go up. The more expecive it gets the better the flow meter.
