  • Publication number: 20230066279
    Abstract: Provided is an ultrasonic flow sensor with improved practicality. An ultrasonic wave is transmitted and received by an ultrasonic element. A first flow rate value of a fluid in a pipe is calculated based on a propagation time difference of an ultrasonic signal, a measurement value corresponding to an ultrasonic velocity, and a parameter for identifying an inner diameter of the pipe. A second flow rate value of the fluid in the pipe is calculated based on a frequency shift of the ultrasonic signal and the parameter. The first flow rate value is calculated using a propagation time of the ultrasonic signal as the measurement value in accordance with a correspondence relationship among a distance of a path through which the ultrasonic wave propagates through the fluid in the pipe, a time for which the ultrasonic signal propagates in the path, and the ultrasonic velocity.

  • Patent number: 11408560
    Abstract: Recording a history related to an operation of a safety program contributes to a determination of a cause of a false OFF signal. A safety controller acquires, from at least one safety input device or safety sensor, extra information that is not used for obtaining an output signal and records an input signal and an output signal together with the extra information as history information at predetermined recording intervals.
