ABSTRACT:
Apparatus utilizes two or more orifices in series, fixed normal to the flow field, which provide a pressure reservoir from which the static pressure is sensed for the purpose of sensing variations in flow within a tube. The apparatus comprises a plurality of orifices, flow regulators, pressure repeaters and electrical pressure switches all connected so as to function as a complete system.
