Aim of the Experiment Creating a calibration curve for an orifice. The measuring nozzle is used as a reference. Preparing the Experiment 7 ● Equip orifice holder with desired orifice disk ● ● ● Flow Rate Measurement with Orifice gunt 230 ● ● Disassemble the orifice holder by loosening the four screws in the center. Place the orifice disk with the desired diameter in the center of the recess. Reassemble the holder. Ensure that the orifice disk is centered, and the sealing rings are seated properly in the grooves. Use the union nuts to attach the orifice holder to the measuring nozzle and intake connection. Note: the longer end is the abatement section of the inlet and must be connected to the measuring nozzle. Procedure Connect the pressure measurement points to the differential pressure manometer as shown. 032mm, 025mm: Measuring range 0...600mbar - 019mm, 012mm: Measuring range 0....1mbar. Connect the pressure measurement point for the measuring nozzle to the negative connection of the velocity display. Switch on fan and set the desired flow rate via the speed. ● Record the velocity c at the measuring nozzle and the differential pressure AP. Adjust the flow rate accordingly via the speed and repeat the measurement. Repeat the series of measurement for other orifice diameters. PRACTICAL EXPERIMENT
