Flow Tester CETATEST 915 Flow Tester CETATEST 915 - for volume flow measurement 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. With the optional electronical pressure regulator and four calibrations for up to four test pressures the application range is substantially broadened. Signal processing Fast 24-bit-A/D-Converter Sequence controller Real time microcontroller system, 16-bit pC / 40 MHz Pressure sensors Differential pressure sensor, gauge pressure sensor (test pressure) Pressure ranges -1,000 mbar, 150 mbar, 1,000 mbar, 6 bar, other pressure ranges and electronical pressure regulator on request Maximum Deviations Gauge pressure: 1 % * Specification for combined devices based on positive gauge pressure Volumetric flow: 2 % * Result units ml/min, ml/h, l/min, l/h, mbar*l/s referred to full scale value Measurement ranges of the laminar flow elements Type of LFE Flow at positive gauge pressure Test connections of 50 mbar in the LFE 1 RGK 3 - 250 ml/min 8 x 1 mm fitting
