Model No.PS-2222 Product Description Product Description The PS-2222 General Flow Sensor is a versatile device for measuring differential pressure in air or water. It measures the difference in pressure between the two input tubes. The PASCO General Flow Sensor is designed to work with the ME-2220 Venturi Tube or the ME-2221 Pitot Tube. The Venturi Tube and Pitot Tube attach to the General Flow Sensor by way of a flexible twin tube hose.

Model No.PS-2222 Product Description Pitot Tube (ME-2221) The Pitot Tube is designed to measure flow velocity in open channels. The Pitot Tube has a detachable handle attached to a 1/4”-20 nut.The overall hose length is 6 feet (1.82 m). The tube with the male luer plug is for low pressure measurement and the other tube is for high pressure measurement.

General Flow Sensor Critical Use Considerations For low flow Venturi measurements at a rate of 1 standard cubic foot per minute (SCFM), the measured value of Pdiff was approximately 11 pascals (Pa) and the theoretical Pdiff was 6 Pa. These are uncorrected values with a baseline noise level of approximately 3 Pa. Repeatability is excellent with a variation within the noise band. Item Value Range: 0 to 50 kPa Differential Pressure Accuracy: ±2.5% of Full Scale (at 50 kPa) • Venturi Tube in Water ±2.

Model No.PS-2222 Critical Use Considerations Setup and Use of the General Flow Sensor Connect the Sensor Connect tubes from either the Venturi Tube (ME-2220) or the Pitot Tube (ME-2221) to the General Flow Sensor. Be sure that connections are sealed prior to the introduction of any liquids to the system. Plug the General Flow Sensor PS-2222 into a PASPORT input port on a PASPORT-compatible interface, and turn on the interface. (Check the PASCO web site for compatible interfaces.

General Flow Sensor • Critical Use Considerations Set up the Graph display to show one of the sensor’s measurements on the vertical axis. For example, click the “Select Measurement” menu button on the vertical axis and pick “Diff Press (kPa)” from the menu. “Time (s)” automatically shows on the horizontal axis. Zeroing the Sensor Prior to measurement the sensor should be placed in its operational position, any fluids to be used should be introduced to the system and hoses should be restrained.
