Smart Manometers that use differential pressure sensors can be
programmed to read out flow measurement units such as CFM or
L/min. The primary element must be a differential pressure
producing, square root type of device, such as a pitot tube, orifice
plate or venturi.
The flow constant and flow units description are programmed into
the manometer using the same keystrokes used in the User Unit
Select programming. At step 3 choose "FLOW UNIT SELECT"
instead of "USER UNIT SELECT".
