2.1.1 Water column reading system
A manometric column is used to regulate a reference measuring pressure with the utmost precision (figure 5 ). This pressure is fed into a chamber via a reference nozzle, to which a measuring pressure column and measuring nozzle are connected. Depending on the air leakage at the measuring nozzle, the pressure in the chamber assumes a...
