FIELD: metrology.
SUBSTANCE: sensors for measuring viscosity and density of a fluid. The sensor contains a generator, a vibrating element that is in contact with the liquid. The vibration sensor measures the vibration characteristic of the vibrating element. The sensor electronics generate and send an excitation signal to the driver and receive the vibration characteristic, then measure the first vibration characteristic point and the second vibration characteristic point for the vibration characteristic. The second vibration characteristic point is calculated by interpolation and extrapolation from the other measured characteristic points. The processor of the measuring device then calculates the quality factor Q of the vibration element using the first vibration characteristic point and the second vibration characteristic point.
EFFECT: increased accuracy of quality factor measurement.
