A flow rate measurement system being a flow rate measurement system that measures a flow rate of molten metal flowing through a hollow portion of a pipe includes an excitation coil that generates a magnetic field so as to intersect with the molten metal flowing through the hollow portion of the pipe; current supply processor circuitry that supplies an alternating exciting current to the excitation coil; a detector that detects a signal based on a magnetic field generated from the excitation coil by an alternating exciting current flowing through the excitation coil or a time variation in the magnetic field; and flow rate deriving processor circuitry that derives the flow rate of the molten metal based on the signal detected by the detector, wherein the pipe is arranged between the excitation coil and the detector, and a magnetic field that reaches the detector across the pipe is generated from the excitation coil.

The application provides a body fat rate testing method and system, which comprises the following steps: after starting the test, placing a human body to be tested in a body fat tester, generating an excitation signal through electrodes and collecting a human body surface response signal in two postures of standing and lying, respectively, processing the response signal to obtain impedance amplitude and phase, judging whether the impedance amplitude and phase reach preset values, if yes, calculating body fat rate impedance Z1 and Z2 in the two postures, respectively, further calculating the final body fat rate according to Z1 and Z2, displaying the result through a display, and sending the result to a terminal device. The application can improve the accuracy and reliability of body fat rate measurement, has the characteristics of convenient operation and strong applicability, and can provide more accurate body fat rate evaluation for health management and medical monitoring.

This safety device (10A) for a flow rate measurement device comprises: internal communication units (12a, 12b) (the number of internal communication units may be one) that communicate with a flow rate measurement device for measuring the flow rate of a fluid; a safety assessment processing unit (11) that assesses the execution of a safety function by the flow rate measurement device by using output information from the flow rate measurement device, said output information being obtained through communication performed by the internal communication units (12a, 12b); and an authentication unit (13) that generates, as at least authentication information, an indicator value included in the output information from the flow rate measurement device, and, on the basis of the authentication information, assesses authentication with the flow rate measurement device with which communication is to be performed. This makes it possible, even with, e.g., a flow rate measurement device that does not have a safety function, to implement a safety function that is suitably reliable for the flow rate measurement device.

The present invention relates to a method of measuring the wear of a fifth wheel locking mechanism, which, in existing fifth wheel systems, enables the service life of the fifth wheel to be increased by automatically measuring the amount of wear and transferring it to the user.

The present invention provides an error rate measurement device and method that can detect specific patterns in real time without being affected by unique data that the object under test may transmit along with specific patterns in response to state transitions, thereby enabling expected error measurement. [Solution] The error rate measuring device 1 is configured to include: a pattern setting control unit 602a that sets a specific pattern that is expected to be output from the DUT 10 according to the state of the LTSSM, and a mask pattern that specifies the location of the unique data transmitted together with the specific pattern; an ED5b that measures the error rate of the specific pattern in the input signal by sequentially comparing a detection signal synchronized with the timing at which the beginning of the specific pattern is detected with an internal signal; and a measurement control unit 603g that uses a mask pattern to control the ED5b so as not to measure errors at the location of the unique data in the specific pattern.
