The flowmeter has a simple and effective metering design, which is composed of a frame and three rotors that rotate uniformly in the metering device. There is no metal to metal contact in the flow tank, eliminating any deterioration in accuracy and providing a long service life. The rotor is supported by a bearing inserted in two bearing discs, and a timing gear is arranged at the end of each rotor shaft. Then the timing rotation between each rotor will be transferred from the scale adjuster to the register, which will produce consistent and high accurate measurement.
