FLOWMETRING AND ACOUSTIC STUDY OF A GAS FLOWRATE LIMITER 

Fares Ben Rayana

Abstract

The CRIGEN had realized a wide experimental study on gas flowrate limiter used on compact meter station for measuring gas flow at variable pressure. This device is used to control and limit, for a specified pressure, the flowrate of the meter station. It is a perforated plate with a constant holes size. Each hole is functioning as a sonic nozzle. The number and size of the hole are defined by the meter station maximal flowrate. This paper shows that the flowrate limiter geometry (the hole size, the ratio plate thickness/hole size and the number of holes) can be changed without affecting the meter station characteristics: flowrate range, residual pressure loss. In the other hand the noise produced by this device can be decreased by reducing the hole size.
