Page 7: Application
Heinrichs Messtechnik GmbH 3 Application The magnetic-inductive flow velocity sensor PIT-UMF2 is used to measure or monitor the volume flow of liquids with and without solids concentration, slurries, pastes and other electrically conductive media while minimizing pressure drops. The medium must possess a conductivity of at least 20 µS/cm. -
Page 8: Mode Of Operation And System Design
Heinrichs Messtechnik GmbH 4 Mode of Operation and System Design 4.1 Mode of operation It was back in 1832 that Faraday suggested utilizing the principle of electromagnetic induction for measuring flow velocities. His experiments in the Thames, though unsuccessful due to superimposed polarization effects, are nonetheless regarded as the first ones in the field of magnetic-inductive flow measurement. -
Page 9: System Design
The PIT-*** sensor can be operated with all transmitters for magnetic-inductive flow meters manufactured by Heinrichs Messtechnik. The sensor is installed (inserted) into the pipe while the transmitter is mounted directly on top of the sensor or separate remote, depending on the equipment design. -
Page 10: Remote Installation Of The Transmitter
4.2.2 Remote installation of the transmitter Heinrichs Messtechnik recommends this type of installation when there is little space or the medium temperatures are high. The sensor and the transmitter are connected by a field coil and an electrode cable. The electrode cable must be shielded and protected against disturbing interferences. -

Page 12: Conditions Of Use
Heinrichs Messtechnik GmbH 6 Conditions of use 6.1 Installation conditions Disturbing elements (e.g. shut-off and control valves) are to be arranged downstream from the sensor. If this is not possible, flow conditioners must be installed so that no vortexes can reach the pipe section of the sensor. -
Page 13: Grounding
Heinrichs Messtechnik GmbH 6.1.3 Grounding For safety reasons and to ensure faultless operation of the magnetic-inductive flow meter, earthing of the flow sensor is important. In accordance with VDE 0100, Part 540, the earthing connections must be connected to the grounding conductor. -
