Latest Patents

One of Matsumoto's latest inventions is a mass flow meter. This device provides improved accuracy in measuring the mass flow rate of a fluid flowing through a straight measuring tube. The mass flow rate value is influenced by parameters such as the Young's modulus, second moment of area, length, and axial force of the measuring tube. A strain sensor is installed on the measuring tube to correct the measured mass flow rate based on its output. This correction is conducted separately for the substantial mass flow rate and the zero point offset, enhancing measurement accuracy. Additionally, a temperature sensor is included to further improve measurement precision, as temperature also affects the parameters of the measuring tube.

Another significant invention by Matsumoto is a vibration measuring instrument. This device improves the precision of phase difference calculations through corrections based on outputs from a frequency ratio calculating unit and a temperature calculating unit. The phase or time difference of each output signal from a vibration sensor is influenced by the temperature and axial force on the measurement pipe. This innovation allows for more accurate readings of mass flow or density of a fluid.
