ABSTRACT:
A flow measurement probe measures reactor coolant water flow in a cold leg pipe of a nuclear reactor system wherein a lack of elbows precludes the use of elbow tap flow measurements. An elongated probe body disposed in the pipe includes a common dynamic pressure tap in the peripheral wall of the probe body facing about into the direction of coolant water flow. A plurality of static pressure taps are oriented about normal to the direction of coolant water flow. Each of the static pressure taps is operatively connected witch one input of a different differential pressure transmitter. The other input of each of the transmitters is operatively connected with the common dynamic pressure tap. The differential pressure measured by each transmitter is proportional to the square of the magnitude of reactor coolant water flow. The multiple taps in the probe allow multiple redundant flow measurements to be made with a single device, thus avoiding the need for multiple penetrations in the pipe.
