Multi Tube Manometer
Product Code : EL-AEFT-11265
Quick Answer: The Multi Tube Manometer uses water as its working fluid, held in a small reservoir beside the tubes. Thumbscrew fixings let the tubes be inclined from fully vertical to 80 degrees to read very small pressure changes.

About This Product
A multi tube manometer lets students read many pressure points at once, for example from a pressure-tapped model in a wind tunnel. Tilting the tubes spreads a small change in level over a longer length of tube, which raises the sensitivity for the low pressures found in air flow experiments. Schools, colleges and institutes in Panama, Guinea-Bissau, Guyana, Indonesia, Montenegro and Qatar can order the Multi Tube Manometer from Educational Instrument.
Frequently Asked Questions
Why can the manometer tubes be inclined?
Inclining the tubes from vertical towards 80 degrees changes the magnification, so very small pressure changes are easier to read.
How is the zero level set?
The reservoir height can be adjusted to change the datum of the water levels, and adjustable feet level the manometer before use.
