FLUID LEVEL MEASURING INSTRUMENT FOR A NUCLEAR POWER PLANT

摘要

A measurement chamber (18) having an upper and a lower region is at substantially the same elevation as a horizontal pipe (12) having a top region and a bottom region. An equalization line (14) fluidly connects the top region of the pipe (12) to the upper region of measurement chamber (18). A sample line (16) fluidly connects the bottom region of pipe (12) to the lower region of the measurement chamber (18). Heat junction thermocouples (22) generate a signal indicative of the level of fluid in the measurement chamber (18) which is equal to the level of fluid in the pipe (12). The signal is transmitted to a remote location by line (24).
