RE: Flow meter -orific plate

for liquid flow here is an Excel file in comma delimated format. Copy and save this as orifice.csv then open with Excel

Remove the " from around the formula and it should work. (the numbers in the column next to the formula are the results with the given example.)

lET ME KNOW IF YOU NEED A SPREADSHEET FOR GAS SIZING

RE: Flow meter -orific plate

Suggestion: Please, would you post more info about a kind of the flowmeter you have in mind.

RE: Flow meter -orific plate

A good question it all depends on the product you are trying to measure (single/dual phase, gas, liquid, slurry etc), also the overall accuracy (uncertainty) you are trying to achieve. International Standards covering the measurement of flow to high accuracy are again quite numerous, ISO 5167 (BS1042) and AGA 3 are probably the most widely used and are available from their respective organisations. If you require any further information please let me know and I can point you in a direction or two.
