General
A complete magnetic flowmeter system consists of two components: the Smag62 microprocessor-based integral-mount
magneti flowmeter transmitter and a flowtube.The flowtube is installed in-line with process piping, either vertically
or horizontally. Coils located on opposite sides of the flowtube create a magnetic field, and conductive liquid moving
through the magnetic field generates a voltage that is detected by two electrodes.The transmitter controls the generation
of the magnetic field and senses the voltage detected by the electrodes. Based on the sensed voltage, the transmitter
calculates a flow rate and produces analog and frequency output signals proportional to this flow rate.

    Never place anything through the flowtube for the purpose of lifting or gaining leverage.Liner damage can render the flowtube useless. 5.3.1 Identify Options and Configurations Standard application of the Pmag includes control of the flowtube coils and one or more following configurations or options: - 4÷20 mA Output...
  • Page 7: Environmental Considerations

    5.7 Environment of the installation 1) The Pmag must by mounted in dry and well ventilated site. Not install the instrument in the place where the water is easily accumulated. 2) The instrument should not be exposed. Shelter is needed where the instrument is installed outside.
  • Page 8: Preparation For Operation

    Pmag - Installation 5.9 Grounding The grounding of the instrument must be satisfied because the signal the instrument measured is very weak, only a few milli-voltages, even at its full range. See figure 9 for the grounding position. There are two requirements for grounding: 1) The sensor and the fluid must be equipotential.
  • Page 9: Electric Connection

    - Connect + DC. - Connect - DC. 6.3 OUTPUT Satisfy these requirements before attempting to install and operate the Pmag. 6.3.1 Analog output The loop may be powered from the transmitter itself. Resistance in the loop must be 750ohms or less.

    8. LOCAL OPERATOR INTERFACE (LOI) The LOI option is an operator communications center for the Pmag. Through the LOI, the operator can access any transmitter function for changing configuration parameter settings, checking totalized values, or other functions. 8.1 SAFETY MESSAGES Instructions and procedures in this section may require special precautions to ensure the safety of the personnel performing the operations.
  • Page 11 Pmag - Setting 8.4 LOI ROTATION Each magnetic flowmeter installation is different from application to application; therefore, the LOI display can be rotated to accommodate various setups using the following procedure: 1. Remove power from the transmitter Unscrew and remove the LOI cover. Do not remove the cover in explosive atmospheres when the circuit is alive.

    Pmag - Troubleshooting 9. TROUBLESHOOTING Problems in the magnetic flowmeter system are usually indicated by incorrect output readings from the system, error messages, or failed tests. Consider all sources when identifying a problem in your system. Process Noise: In some circumstances, process conditions themselves can cause the meter output to be unstable. The basic procedure for addressing a noisy process situation is outlined below.
