  • Publication number: 20180348031
    Abstract: A thermal flowmeter comprises a heating element thermally coupled to a flowing medium, a first temperature sensor and second temperature sensor. The first temperature sensor detects a flowing medium temperature in a region not affected by the heating element. The second temperature sensor detects a temperature of the heating element and also serves as a heating element. A control unit controls heating power of the heating element based on the difference between the detected temperatures at a predetermined time. The control unit provides a square wave signal to the second temperature sensor so that in a high phase it acts as heating element and in a low phase as a temperature sensor.

  • Publication number: 20170282225
    Abstract: The invention relates to a method for the time control of an automated cleaning process in a tank container, wherein during the cleaning process cleaning liquid is sprayed onto the inner wall of the tank container by means of a spray head. According to the invention the following method steps are provided: detecting the heat removal of a heating element disposed in the flow-off area of the cleaning liquid; continuous determination of the state value of the cleaning liquid with regard to the two variables degree of contamination and spray rate by means of the heat removal; comparing the state value of the cleaning liquid in a quasi-stationary state with a target state value; and terminating the cleaning process when the current state value differs by less than a default value from a target state value.

  • Patent number: 9243941
    Abstract: A magnetic-inductive flowmeter with a nonconductive measuring tube, a magnetic field generating apparatus, two measuring electrodes conductively coupled to the medium for tapping a measuring-circuit voltage induced in the flowing medium, and with a measuring device for detecting an empty tube. Detection of an empty tube is obtained by the measuring device being an admittance measuring device having a detector, a counter-electrode, an ac signal source and an evaluation unit, the detector having an electrode connected to the ac signal source so that the electrode is exposed to an ac signal in the range of roughly 50 MHz-200 MHz and then an electrical field extends from the electrode into the medium. The electrode of the detector and the counter-electrode planiform shaped and are located essentially opposite one another on the outer surface of the measuring tube above and underneath the longitudinal axis of the measuring tube, respectively.

  • Patent number: 6471395
    Abstract: A heat transfer monitoring and/or measuring device, especially a flow indicator for media flowing through a pipe (1), tank or fitting, with a sensor housing (2) and with two sensor elements (3, 4), the sensor elements (3, 4) each having a metallic sensor surface (5) which comes into contact with the flowing medium. In the flow indicator, the problem “deposition or formation” of disruptive layers on the sensor surfaces (5) of the sensor elements (3, 4) is solved by the element (3) which is made as a heating element having an electrically conductive protective lead (6) and by the protective lead (6) forming a closed protective circuit which includes the pipe (1), tank, or the fitting, the flowing medium and the sensor element (3).
