    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
    How many wires do the RTD versions of the TE Series Temperature Sensors have?
    Answer
    The TE Series Temperature Sensors are all two-wire sensors for both the thermistors and RTD’s.

    Question
    What purpose does the sintered filter perform on the RHP transmitter and does its use preclude adding the LCD option? Is it recommended when transmitter is located just after blower but before cooling coil?
    Answer
    The sintered filter is recommended in applications where you expect to be close to the temperature limit of the RHP (near 140°F) because the sintered filter has higher temperature resistance than the standard fiber membrane filter. You can order the sintered filter version with or without an LCD screen.

    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.
