Definitions

  • the invention also relates to a device for non-invasive measurement of the liquid level in a metal tank, comprising an ultrasonic transmitter and an ultrasonic receiver; at least one connector for connecting the transmitter and receiver to the outside of a bottom wall of a metal tank; a power supply connected to the transmitter and the receiver and an intelligent control unit connected with the transmitter and the receiver for measuring the time period between the moment of transmitting a signal and the moment of receiving the corresponding reflected signal and calculating the height of the liquid surface to the transmitter and/or receiver based on the on the measured time period.
  • a power supply connected to the transmitter and the receiver and an intelligent control unit connected with the transmitter and the receiver for measuring the time period between the moment of transmitting a signal and the moment of receiving the corresponding reflected signal and calculating the height of the liquid surface to the transmitter and/or receiver based on the on the measured time period.
  • a load may be connected to the transmitter/transceiver/transducer in order to deaden the reverberation before any return signals arrive to be detected.
  • Metal walls are known for causing heavy reverberation of acoustic signals making it more difficult to accurately detected any reflected signals. Furthermore, it may prevent distinguishing any echo signals and reverberation.
  • the intelligent control unit may comprise an AD- converter.
  • the AD-converter may measure the ultrasonic response signal. When the response echoes have regular intermediate time intervals they are more likely to be identified as reflections of an originally send ultrasonic pulse. The echoes may be measured until a consecutive pulse is send.

Abstract

L'invention concerne un procédé de mesure non invasive du niveau d'un liquide dans un réservoir métallique, comprenant les étapes de procédé suivantes : monter un émetteur et un récepteur sur l'extérieur d'un réservoir ; transmettre un signal à travers la paroi du réservoir ; recevoir un signal réfléchi, lequel signal réfléchi est réfléchi par la surface liquide d'un liquide contenu dans le réservoir ; mesurer la durée écoulée entre l'émission et la réception des signaux ; et calculer la hauteur du liquide sur la base de la durée mesurée. L'invention concerne également un dispositif de mesure non invasive du niveau d'un liquide dans un réservoir métallique ainsi qu'un ensemble constitué d'un réservoir métallique et d'un tel dispositif.
