The classic type - for flow testings also. Our top-selling flow test device • flow testings according to volume flow method (INTEGRA DF1) • flow testings according to Mass-Flow method (INTEGRA DFM) • full-graphical colour display • up to 3 independent test circuits run capable • 255 test programs storable • communication via intermountable bus-coupling-modules Flow testing devices are especially suited for testing parts with very large filling volume and for medium to large admissible leakage rates. Particularly in the manufacturing of exhaust systems or other big sheet metal cases our devices are used. But also in the control of pass or to verify unwanted restrictions in tubes or channels our flow devices provide excellent possibilities in a wide measuring range. Another scope is the inspection of air permeable materials like membranes or filters. For the flow method the test piece is filled via a bypass pipe with large diameter. At the end of the filling process, the bypass valve is closed. The air escaping from the test piece is led to a flow sensor. After an adjustable stabilisation period, the measured flow is evaluated. For measuring, either a mass-flow sensor (mass flow measurement) or a Laminar-Flow-Element with a differential pressure transmitter (volume flow) is used. For the mass-flow measurement, the temperature difference of the airflow between input and output of a heated measuring channel is measured. With volume-flow measurement, the difference in pressure in a laminar flow serves as measuring value for the flow.
