Measuring terminal equipment


PURPOSE: To quickly respond to abnormality in the use of a medium by always monitoring the quantity used of an available medium based on a contract, and transmitting the abnormality to a center device within prescribed permission time when the abnormality in the use of the medium is detected. CONSTITUTION: The microcomputer 9 of measuring terminal equipment 22 always monitors the rotation of an impeller 1 i.e., the quantity used of city water based on a pulse from a magnetic sensor 5, and when the abnormality with respect to the use of the city water such as leakage, malfeasant use, a fault, etc., is detected, the fact is transmitted to the center device 13 within the prescribed permission time based on time information from a clock part 23. In such a case, the microcomputer 9 comprises an abnormality detecting means and a transmission control means. In such a way, it is possible to quickly respond to the abnormality with respect to the use of the available medium based on the contract. COPYRIGHT: (C)1992,JPO&Japio
