    Questions

    Question
    How do I hook up my Magnehelic® gage for an air velocity application with a pitot tube?
    Answer
    In our Application Guides on flow products, we explain very well how to take air velocity readings. The total pressure connection on the pitot tube is connected to one of the high pressure ports on the gage. The other high pressure port is plugged. The static pressure connection on the pitot tube is connected to one of the low pressure ports on the gage. The other low pressure port is plugged.

    Question
    My quesiton is regarding PAFS-1000 series averaging flow sensor. Is the K factor provided in the instruction manual a direct multiplier to the velocity measured? i.e. v_actual = v_measured * K.
    Answer
    You are correct. V_actual = V_measured * K.

    Question
    The gland fitting A-159 is shown as an accessory to the Series 160 Pitot tube. How do you install the fitting past the elbow in the tube?
    Answer
    The optional mounting gland, model A-159, is designed to slide over any Series 160, 5/16” diameter standard pitot tube. It should be large enough to slide past the elbow while still being small enough to tighten down on the 5/16” diameter shaft.

    Question
    I have an application where i need to check permanently the velocity in a metal duct (16" diameter) the application is metal cutting (cutting with plasma machine. I am selecting the following items. Series 160S Pitot Tubes and Series DM-1200 DigiMag® Digital Differential Pressure and Air Flow Gage a little dust is generated, could it affect the DM-1200 reading
    Answer
    The 160S pitot tube is specifically designed for flow measurement of dirty, particulate laden gas or air so a bit of dust should not be an issue for your application.
