Abstract

PURPOSE: To perform simple and accurate flow rate measurement by setting the upper limit value and lower limit value of flow rate permissible range by the use of stationary orifices for allowing the flow of specified rates based on the specified fluid pressure.
CONSTITUTION: In the mechanism provided with an upper limit value setting stationary orifince M1 and a lower limit value setting orifice M2 for flowing fluid at the rates corresponding to upper or lower limit under specified fluid pressure and a pressure gauge P2 producing output signals proportional to the flow rates of the fluid flowing in a laminar flow meter RFM, the upper limit value of the flow rate levels is first set by regulating regulating valves MV1, MV2 in the flowline of the stationary orifice M1 and RFM and likewise the lower limit value of the flow rate levels is set in the flowline of the stationary orifice M2 and RFM. Next, the measuring object W is set and it is detected that the fluid pressure of the measuring object has reached the specified value, whereby the goodness or not of the measuring object is judged
