Newton per square meter is a unit of pressure; cubicmeter per second is a measure of air flow. I don't think it makes sense to convert one to the other.
The flow rate through a 90mm diameter pipe can be estimated using the formula for the cross-sectional area and flow velocity. The cross-sectional area (A) of the pipe is approximately 0.00636 square meters. If you know the flow velocity (in meters per second), you can calculate the flow rate (Q) in liters per second by multiplying the area by the velocity and converting cubic meters to liters (1 cubic meter = 1000 liters). For example, with a flow velocity of 1 meter per second, the flow rate would be about 6.36 liters per second.
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.
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.

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.
To calibrate a mass flow meter, first ensure that the meter is installed correctly and that the system is free from flow disturbances. Then, use a calibrated reference flow meter to compare the readings of the mass flow meter at various flow rates across its operational range. Adjust the flow meter's settings or coefficients based on the discrepancies observed during testing. Finally, document the calibration results and repeat the process periodically to maintain accuracy.
it principle denpend on what kind of flow meter. example, magnetic flow meter, it use magnetic force to measuring or coriolis flow meter which is use vibrated capilary tube as sensor. or more info you might watch on youtube.
The purpose of a flow meter is to measure the flow of either air or water. They allow one to measure the total volume of air or liquid flow and the rate of the flow.
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.
The capacity of flow in a 100mm diameter pipe can vary based on several factors, including the fluid type, flow rate, and pressure conditions. However, using the formula for flow rate (Q = A × v), where A is the cross-sectional area and v is the flow velocity, a 100mm (0.1m) diameter pipe has a cross-sectional area of approximately 0.00785 square meters. Depending on the flow velocity, the pipe can carry different volumes of fluid; for instance, at a velocity of 1 meter per second, it can convey about 7.85 liters per second.
