Meter in refers to the restriction of a hydraulic circuits inlet flow. They may only be used when utilizing opposing loads as these systems have no way of preventing a load from running away. These are used to regulate motor speed and ram speeds.
Meter out refers to the circuits restriction of the outlet flow. i.e. a hydraulic ram used for offloading heavy material such as a car lift. A meter out system would be used to regulate the flow evacuating the system as to prevent a run-away and maintain load control.

When a pneumatic cylinder chamber is filled with pressurized air and the air-chamber on the other side of the piston is metered-out by a flow control, the movement or speed of the cylinder is more consistent than to meter-in the pressurized air.
A flow meter is a device that measures the energy flow of either a liquid or a gas. Like if you have nitrous oxide in a tank and you want to know how much is left after you use some, a flow meter would tell you.
Meter in and meter out are terms commonly used in hydraulic systems to control the flow rate of fluid. In pneumatic systems, flow control valves such as needle valves or flow restrictors are used to regulate the speed of the air flow. These components are designed specifically for pneumatic applications due to the differences in fluid properties and system requirements between pneumatic and hydraulic systems.
Bleed off flow control uses excess fluid to regulate the flow, resulting in less precise control compared to meter in and meter out methods. Meter in controls the flow entering the cylinder, while meter out controls the flow exiting the cylinder, allowing for more accurate and controlled movement.
The above is the symbol of flow meter.
rota meter
THE SYMBOL FOR Flow Meter is : FI as Flow Indicator
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.
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.
If this is the Eco Tech Vauxhall Engine then it will either be the EGR Valve (Exhaust Gas Recirculation Valve) or the Mass Air Flow Meter. It's worth disconnecting the Mass Air Flow Meter when it is reving and see if this alters the revs if not then I would suggest cleaning the EGR Valve as they get clogged up with black soot and subsequently alters the air to fuel mixture as would the Mass Air Flow!
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.
