PROBLEM TO BE SOLVED: To attempt energy saving effect by measuring terminal pressure of compressed air to a load device in a distant place efficiently to feed compressed air in a plant without loss.SOLUTION: A compressed air measurement system comprises: a central control unit controlling a feeding amount of compressed air produced with a compressor facility through a header in plant facilities; a header pressure gauge measuring a header pressure; and a terminal pressure transmitter measuring a terminal pressure of the plant facilities side. The terminal pressure transmitter comprises a power generation system and transmits the terminal pressure value to the central control unit by radio communication. The compressed air measurement system detects abnormality of the terminal pressure value and the transmitter in an appointed case. |
