    If the specification uses leakage class, you will need to calculate the total duct system surface area. Oriflow has a free Adobe form available to our customers that will calculate duct surface area given the duct shape, dimensions and length.

  • Page 6: Determining Which Orifice Plate To Use

    After determining the allowable leakage at the system test pressure, refer to the following tables for the capacities of each orifice plate available for the RHINO model tester. Make sure you have an orifice plate that can measure the maximum allowable leakage.

  • Page 11: Connect Flexible Duct To Orifice Tube

    Make sure that the connection where you connect the flexible duct is a sturdy, sealed tight connection. You don’t want to create a leaky connection where the tester is supplying air into the system. Figure 7 – Connection to Duct System © Copyright 2018 ORIFLOW LLC Rev: 03-2018...

  • Page 12: System Test Pressure Connection

    Note you will need an inlet transition to attach to the blower inlet when performing a return/exhaust test. The dimensions of the transition required depends on whether you have a Rhino model with an inlet slide gate or VFD for flow control. See Figure 11 and 12 for inlet transition dimensions required.

    Turn the blower on and slowly open the inlet slide gate for models without the speed control option. If your tester has the VFD speed controller, rotate speed control knob slowly clockwise to obtain system test pressure.

    Always refer to the calibration certificate(s) that came with your calibrated orifice plate(s). Figure 17 –ORIFICE PLATE Gauge Reading (analog on left, digital on right) © Copyright 2018 ORIFLOW LLC Rev: 03-2018...

  • Page 20: Troubleshooting

    (for this example, the constant is "7.206"). The exact leakage is 7.206 x (square root of 725) = 194.0 L/s. Oriflow has FREE Adobe forms available that will calculate the leakage, leakage factor, allowable leakage, Pass/Fail criteria and duct surface area among other variables (www.oriflow.com/freeform).

  • Page 21: Zero Reading On "Orifice Plate" Gauge

    If you feel a lot of air coming out of the tube end, you should see a pressure reading on the gauge “ORIFICE PLATE”. © Copyright 2018 ORIFLOW LLC Rev: 03-2018...

  • Page 22: Can't Obtain System Test Pressure

    Hot water coils and electric heaters,  Open duct end that was supposed to be sealed/capped-off for the leak test. A non-toxic smoke machine is an excellent tool for locating significant sources of leakage. Call ORIFLOW at 727-400-4881 or online at www.oriflow.com for more information.
