Measuring device for micro flow rate and nuclear power plant having the same
First Claim
1. A device for measuring a micro flow rate, the device comprising:
- a container having an internal space for containing a fluid flowing therein and an inflow line and an outflow line formed in communication with the internal space;
a fluid level gauge configured to sense whether a level of a fluid collected in the container rises to a predetermined height, and to conduct or block flow of an electric current depending on whether the level of the fluid rises to the predetermined height;
a control valve disposed in a part of the outflow line extending from the lower portion of the container and configured to open or close the outflow line according to a state in which the control valve is electrically connected to or disconnected from the fluid level gauge such that the outflow line is opened or closed according to a change in the fluid level and configured to allow or block the discharge of the fluid through the outflow line by operation of opening or closing the outflow line; and
a control unit configured to calculate a micro flow rate of the fluid collected in the container using information acquired from at least one of the fluid level gauge and the control valve.
