note = {On the purpose of measuring the flow of .fluids, the small type of orifice meter were made by plastic materials, and sufficient data were obtained to be able to apply for the field of measuring small amount of fluids in laboratory work. The orifice meter which made by plastic materials provide the following relationship between the velocity through the orifice V (cc/min) and difference in head dH, as the equation (1).\ndH=AV＾2+BV (1)where,A=1 /<450T＾2C＾2_0GD＾4>(2)B = <32L/ 15TGD＾4>< M / P > (3) on the equation (1), the term of AV＾2 is a main factor which depend on difference in head and it will be a rate determing factor for dH. Also BV is a sub-term which come from pressure loss in the orifice hole. The equation (1) may ploted on linear relation between (dH/V) and V,\ntherefor there are no dificulties to determine the values of A and B.This small type orifice meter which made by plastic materials will be able to apply for the laboratory work with very high accuracy., 紀要論文},
