Page 8: About This Manual
The manual is divided into a table of contents, eight chapters, seven ap- pendices, four gatefolds and an index. 1. Introduction Contains a presentation of the MJK MagFlux electromagnetic flow ® meter, the structure of this manual and the operating principles.
Page 9 Electromagnetic Flow Meter Appendix B. MJK-Field Link Software Upgrade Describes in detail how to utilise the unique and intuitive MJK-Field Link software program to upload new display and converter firmware versions. Appendix C. FAQs - Frequently Asked Questions Contains answers to questions that are often asked.

Page 11: The Magflux ® Flow Meter
Electromagnetic Flow Meter The MagFlux Flow Meter ® Measurement Electromagnetic flow meters may have either direct current (DC) or alter- nating current (AC) excitation. When systems are AC excited, electrostatic and/or electromagnetic noise may influence the measurements. A DC excited system however, is less sensitive to noise produced by electromagnetic induction, simply be- cause the voltage induced over the electrodes will be a DC voltage.

The flow directions A or B are clearly shown on the name plate. Default flow direction is "A". Pressure loss The pressure loss can easily be determined, if the nominal pipe diameter is greater than the MagFlux flow sensor. See the diagram below: ® Pressure loss graph 0.003...
Page 17: Accuracy
The flow sensor should be selected so the flow velocity through the sensor will be between 0.2 - 10 m/s. MJK recommends that flow velocities in tubes are kept between 1 - 3 m/s for reliable and safe operation. See also the dimensioning table below and the dimensioning chart on the following page.
Page 18: Sizing Chart
Electromagnetic Flow Meter Sizing Chart Example: A MagFlux with an internal diameter of 100 mm can measure flow rates between approx. 290m /h and 5.6 m /h, and the fluid velocity is 1.5 m/s at a flow rate of approx. 42 m...
Page 19: Pipe System
Electromagnetic Flow Meter Pipe System 1. The flow sensor must be mounted in a location which is free from inter- fering elements like valves, Ts, bends, pumps, etc. to ensure a laminar flow without turbulence upstream of the flow sensor. For that reason the flow sensor must be mounted in a straight pipe at a distance from interfering elements of minimum 3 x DN upstream and minimum 2 x DN downstream.
Page 20 4. The flow sensor should always be filled with liquid. For that reason the flow sensor must not be mounted at the highest point of the pipe sys- tem or in free outlets, where gravity could empty or partially empty the pipe. GB MagFlux Manual 0812...
Page 21 Electromagnetic Flow Meter 5. The flow sensor can be mounted vertically or horizontally. If the flow sensor is mounted vertically, the flow direction should always be upwards. In that way the effect from possible bubbles in the liquid will be significantly reduced, just as it will ensure that the flow sensor is always filled with liquid.
Page 22: Cabinet Mounted On The Flow Sensor
If the flow sensor is rotated more than 45°, one of the electrodes may not be in full contact with the liquid. Cabinet Mounted on the Flow Sensor The cabinet is mounted on the flow sensor with four pcs. 6x12 hex cap screws. GB MagFlux Manual 0812...

Page 117: Appendix C. Faqs - Frequently Asked Questions
Electromagnetic Flow Meter Appendix C. FAQs - Frequently Asked Questions ****************************************************************************************** Question: Which size flow meter should I choose for my installation? I would prefer a flow meter with the same diameter as the tube(s). Answer: The minimum and the maximum flows determine the size. Use the size chart (on page 18) to find the correct flow meter size, and avoid tend- ing to select a too large size.
Page 118 MJK flow meters with DN ≤ 50 must always be equipped with ground- ing rings. MJK flow meters with DN > 50 have a built-in ground elec- trode that makes grounding rings superfluous. Coated metal tubes always require grounding rings.
Page 119 Electromagnetic Flow Meter ****************************************************************************************** Question: I have an "Empty pipe" indication, but the pipe is not empty! Answer: There aren't any grounding rings, or the rings have not been properly grounded. See examples on page 23. ****************************************************************************************** Question: I can't set the counter to the required output, only to a value that is higher.
