ABSTRACT:
An apparatus for measuring volume flow through a gear-type flowmeter, having a magnetic sensor affixed to the flowmeter to detect incremental movement of the flowmeter teeth. The sensor is connected to an analog-to-digital converter and computer processor, which receives and stores samples of the sensor signals. The samples are compared with subsequently received samples to derive relative gear positions and to calculate volume flow based on the relative gear positions. The samples may also be analyzed and compared with previous samples to detect flowmeter wear and wobble conditions.
