Abstract
PURPOSE: To monitor the state of valve operation, in particular to find if there is any leakage, with accurate discriminating performance by installing an acoustic noise sensor in the housing or conduit of a fluid opening/closing valve and by comparing the sensed noise level with a previously set reference value.
CONSTITUTION: Noises generated by the fluid passing through the valve are sensed by an acoustic sensor 1 installed in the housing or conduit of a fluid opening/closing valve, and the output obtained is placed in a discriminator device 5 through a preamplifier 2, a signaling device 3 and main amplifier 4. The discriminator device 5 compares the input data with the preset reference value to judge the state of valve operation, and the result of judgement is displayed on a display 6.
