Rotameter
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.
To measure the flow rate of powder in a vertical pipe, you can use equipment such as a gravimetric feeder or a powder flow meter. These devices can measure the mass of powder passing through the pipe per unit of time. Alternatively, you can also calculate the flow rate by measuring the time it takes for a known volume of powder to pass through a specific point in the pipe.
The calibration curve for an orifice meter will depend on the size of the orifice, the size of the pipe and the pressure loss over the meter. Typical calibration curves have pressure (or head) loss on the vertical (y) axis and flow rate on the horizontal (x) axis.

Air flowing quickly over the open top of a vertical tube lowers the air pressure in it. This causes liquid in the tube to rise. (It rises due to the higher pressure acting on the other end. The tube is marked to indicate the wind speed. Alternatively, if the open vertical tube is in still air and it is connected at its lower end with a horizontal tube containing a flowing liquid, the liquid in the vertical tube will fall when the horizontal flow past the lower end increases.
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.
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.
Lateral moraine is not oriented perpendicular to the direction of ice flow. It forms along the sides of a glacier and runs parallel to the ice flow direction.
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.
