  • Patent number: 7448281
    Abstract: A magnetic induction flowmeter having a metal measuring tube (1), which can be inserted into a pipeline system via flanged sections (2a, 2b) at the ends, having at least two mutually opposite measuring electrodes (5a, 5b) introduced into the wall of the measuring tube (1) in an electrically insulated manner in order to register a measuring voltage, a magnetic unit (4), likewise arranged on the outside of the measuring tube (1), generating a magnetic field aligned substantially at right angles to the flow direction of the conductive flow medium to be measured, and the measuring tube (1) being provided with an electrically insulating layer (6) on the inside; in the region of the flanged sections (2a, 2b) at the end of the measuring tube (1), an expanded lattice (7) being fixed to the measuring tube (1), to which lattice the insulating layer (6) is applied in such a way that the expanded lattice (7) located within the insulating layer (6) ensures a firm connection between insulating layer (6) and measuring tube

  • Patent number: 7412901
    Abstract: A magnetic-inductive flow meter with a measuring tube (1) made of metal, which is flowed through by a medium (4) which has a minimum electrical conductivity and is permeated by a magnetic field generated by means of an arrangement of magnets (5), in the region of which field at least two measuring electrodes (6) arranged diametrically on the measuring tube (1) are provided for sensing the inductively generated measuring voltage, the metal measuring tube (1) being provided with an electrically insulating inner layer (7) and an electrically conductive grounding disk (8) being arranged at the end face for grounding the medium flowing through the measuring tube (1), which disk is connected to ground via the measuring tube, the grounding disk (8?) consisting of an electrically conductive plastic which comes to lie in sealing contact directly against the end face (2) of the measuring tube (1) in order to be connected to ground by the direct contact.

  • Patent number: 7270014
    Abstract: A magnetoinductive flowmeter for a medium (2), which is flowing through a measuring tube (1) and has a minimum electrical conductivity, having at least two electric coils (3a, 3b), which are arranged opposite one another on the measuring tube (1), for the purpose of inducing a magnetic field running essentially perpendicularly with respect to the longitudinal axis of the measuring tube (1), and having an electrode arrangement (4), which is likewise aligned essentially perpendicularly with respect to the longitudinal axis of the measuring tube (1) and essentially perpendicularly with respect to the magnetic-field axis, for the purpose of measuring a measurement voltage induced as a result of the flow of medium (2), the electric coils (3a, 3b) being accommodated such that they are sealed on the outside in each case one associated housing part (4a and 4b, respectively), which housing parts are in the form of hollow-cylinder segments and are mounted detachably on the measuring tube (1) by being joined together so

  • Publication number: 20060169054
    Abstract: The present invention relates to a magnetic-inductive flow meter with a measuring tube, which can be fitted into a pipeline system by using connecting means, with at least two measuring electrodes that are fitted into the wall of the measuring tube opposite each other in an electrically isolated manner and are intended for sensing a measuring voltage, a magnet unit, which is likewise arranged on the outside of the measuring tube, generating a magnetic field that is aligned substantially perpendicularly in relation to the direction of flow of the conductive flow medium to be measured. In order to provide here a magnetic-inductive flow meter for low-pressure applications which can be easily produced and can also be easily fitted into a pipeline system, it is proposed here according to the invention that the the measuring tube (1) is produced from a semifinished tube made of high-density polyethylene (HDPE), which can be fitted into the pipeline system (2) without any flanges.
