Automatic Measurement System for Determination of Leakage Flow Rate in Compressed Air Pipeline System

Dindorf R., Wos P.

Vol. 25, nr 1

A new method of indirect flow rate measurement in a pneumatic pipeline system was developed by the authors. The method enables to measure the controlled leakage in a branch line and was used to construct automatic measuring systems auditing the compressed air systems (CAS) piping. In the CAS audit the volume and cost of the leakage in a compressed air pipeline system is evaluated. Based on the authors’ patent, an automatic measuring system (AMS) for measurement of the leakage flow rate in industrial compressed air system piping, was developed. The AMS consists of a measurement device (MD) and a control system (CS). In the measurement device (MD) a novel bifunctional pneumatic proportional control valve is used. The AMS system will be used in the new research project “Mobile laboratory of compressed air system audit” based on the authors’ concept.
