ABSTRACT:
A device for watching the flowing condition of a gas in a conduit, which device is provided with a liquid tube connecting a velocity pressure point with a static pressure point, whereby the liquid tube comprises a chamber which is divided by a freely movable partition into two leak tight, mutually separated compartments and separates the liquid tube into two sections which each with one end open into a compartment of the chamber and with their other end are connected with the velocity pressure point and the static pressure point of the conduit respectively, the chamber having a volume which corresponds to the product of the maximum admissible height of the liquid column and the cross-section of the liquid tube.
