The flow tester CETATEST 915 is used to measure the flow using compressed air. The device contains a measurement system consisting of a laminar flow element (LFE) and a differential pressure sensor. In the direct test method the air, provided by the internal pressure regulator, flows through the measuring section before it enters the test part. In the indirect test method the measuring section is located behind the test part. Due to the special design of the measuring section a laminar flow is generated. The resulting pressure difference is directly proportional to the volume flow.

The CETATEST 915-G is a fully automatic flow test device for the detection of untight parts. The test is automatically started after adaption of the test part. This method of operation has been especially developed for the gas industry and for reworking in the automobile industry. The pressure drop of the laminar flow element (LFE) is measured by a differential pressure sensor and converted into a flow value.
