n: an orifice meter with an automatic integrating device. It is constructed so that the product of the square roots of the differential and static pressures is recorded on the chart. The products are continuously totaled and shown on a counter index. When the product total is multiplied by the orifice flow constant, the rate of flow is determined directly.

n: (C) a factor used in the calculation of gas volume flow through an orifice meter. Mathematical accounting for variations in pressure. temperature. density. and so on. of a gas as it flows through an orifice of a particular size.
