ABSTRACT:
A leak detection system for gas, steam or the like in a plant yard includes a plurality of sampling modules and wind direction and velocity indicators both arranged around apparatus or equipment in the plant yard. Samples of the atmosphere around the apparatus or equipment are drawn through the sampling modules, and the concentration of a substance leaked into the atmosphere is detected by a sensor module. At the same time, the direction and velocity of wind in the plant yard are determined. Leakage of gas, steam or the like in the plant yard can be detected based on the concentrations and wind direction and velocity. Methods for the determination of the direction and/or velocity of wind, wind direction and velocity indicators, and anemoscopes are also described.
