In one embodiment, a method includes a data processing unit obtaining from a sensor a signal representing a series of measurements of a physical parameter associated with fluid flow through the conduit.

Abstract: A system and method for measuring fluid flow rate in a system where fluid is pumped, such as a gas monitoring instrument where gas is pumped from a space such as a room or enclosure through a conduit to a sensor. The flow of gas through a pump is determined by measuring motor back-e.m.f. which is proportional to motor speed.
