Latest Patents

Oosawa holds a patent for a Coriolis mass flowmeter. This invention features a vibration tube that is fixed to a housing at both upstream and downstream points. The design allows the vibration tube to perform simple harmonic oscillation or circular motion around an original axis. This unique configuration ensures that the length of the vibration tube remains constant, regardless of its position. As a result, the tensile force in the direction of the axis is always stable, eliminating leakage of vibration due to variations in force. The enhanced isolation of vibration contributes to the stability and accuracy of the flowmeter. Additionally, the high Q value of the internal vibration minimizes the impact of vibration noise, reduces power consumption, and mitigates changes in zero and span due to vibration leakage.
