PURPOSE:To offer an adjusting meter capable of building a discentralized instrument system requiring less instrument wiring by using a sensor or an actuator, a transmission interface and the adjusting meter in one body. CONSTITUTION:The adjusting meter 1 detects the state of a controlled system 4 such as a pressure tank with the aid of a sensor 2 such as a manometer, drives the actuator with a valve according to a value set by an operator console 5 through the transmission interface 6 and a data way 7, and holds the controlled system 4 at the set value. The main body of the adjusting meter 1, the sensor 2 and the transmission interface at the adjusting meter side are formed in one body, and therefore the number of signal lines and their lengths can be reduced.
