Description of DIDAC Multi Tube Manometer:
A Multi Tube Manometer with a common reservoir, that may be used to give a graphic display of pressure distribution on multi-point pressure tapings.
Multi Tube Manometer allows up to 16 pressures to be monitored simultaneously either relative to atmospheric pressure or another pressure, via the common reservoir. In order to increase the device sensitivity the device may be inclined at a known angle.
Multi Tube Manometers are highly useful for capturing pressure distributions from multiple pressure ports on bodies subjected to air flow past them. The adjustable inclination of Multi Tube Manometer helps in enhancing the contrast in the distribution. The inclination also increases the reading value thus increasing the accuracy of the measurement. Water or Methyl Alcohol and Mercury can be used as the fluid in these kinds of manometers. Mercury is used only for high speed flows like that in Supersonic wind tunnels
