たことを特徴とする流量計。 A casing that is installed in a flow tube and has a measuring chamber bored therein, a pair of rotors that rotate around a fixed axis according to the flow rate of fluid flowing into the measuring chamber, and a sensor that detects the rotation of the rotors. and a preamplifier that amplifies and calculates the sensor output, a cylindrical transmitter magnet held between the rotor bearings and a magnetic sensor that is sensitive to the transmitter magnet and is embedded in the detection cylinder are used to detect the flow rate. Regardless of the shape and dimensions of the sensor, the detection tube, the preamplifier, and the protection tube through which the signal line is inserted are integrally configured, and the detection tube, the preamplifier, and the protection tube through which the signal line is inserted are integrated. A flow meter, characterized in that the detection tube is eccentrically inserted into the fixed shaft, and the component is attached to the housing via a spacer and an annular body.
