Accuracy, Reference Conditions and Operating Principles
ConstructionA special position is filled by the electromagnetic flowmeters in the Compact Design. The converter modules (CM) are mounted di-rectly on the flowmeter primaries in this design. This results in re-duced space requirements, lower installation costs because a signal cable between the primary and the converter is no longer re-quired.
Operating PrinciplesThe basis for the electromagnetic flow metering are Faraday’s Laws of Induction which state that a voltage is induced in a conduc-tor as it moves through a magnetic field.
This principle is applied to the flow of a conductive fluid in the meter tube through which a magnetic field is generated perpendicular to the flow direction. (See Schematic Fig. 2).
The voltage induced in the fluid is measured by two diametrically oriented electrodes. The signal voltage UE is proportional to the magnetic flux density B, the electrode spacing D and the average flow velocity v.
Since the magnetic flux density B and the electrode spacing D are constant values it can be seen that a proportionality exists between the signal voltage UE at the electrodes and the average flow veloc-ity v. From the equation for volume flowrate it follows that the signal voltage UE is also linearly proportional to the volume flowrate qv.

Flowrate NomographThe volume flowrate is a function of the flow velocity and the size of the flowmeter primary. The Flowrate Nomograph (Fig. 6) shows the flow ranges associated with each flowmeter size and which flowmeter sizes are suitable for a specific flowrate.
Example:Flowrate = 120 l/min (maximum value = flow range end value). Suitable are flowmeter primary sizes DN 20 - 65 / 3/4” - 2-1/2”.

Installation Requirements, Flowmeter Primary
Up-/Downstream Straight Pipe SectionsThe operating principle is independent of flow profile as long as standing eddies are do not extend into the metering section (e.g. after space bends, tangential entries or partially open valves or gates). Under such conditions measures must be taken to condi-tion the flow profile.
Straight sections with the same inside diameter as the inlet diam-eter of the flowmeter primary should be installed up- and down-stream. The length upstream of the flowmeter should be at least 10 times the diameter of the flowmeter primary and downstream at least 5 times.
Experience has shown that in most instances straight sections with a length of 3xD upstream and 2xD downstream suffice.
Flowmeter Primary InstallationWhen installing the flowmeter primary the flow direction should be taken into account (flow is into the electrical plug connector) be-cause it is preferable to operate the primary in the forward flow di-rection. It is possible to change the direction indication from forward to reverse in the software. In vertical installations the flow-meter should be installed so that the electrical plug connector points downward. The flowmeter primary must be installed is a such a manner that the meter is always filled with fluid. Valves or other shut off devices should be installed downstream from the flowmeter primary so that the meter cannot drain.
GroundingGrounding is essential for safety considerations and to assure trou-ble free operation of the electromagnetic flowmeter primary. The ground screw on the flowmeter primary is to be connected to a ground for operating reasons. An additional ground to the connec-tion terminals is not required.
For plastic pipelines or pipes lined with an insulating material the ground is made using a grounding plate or grounding electrodes (only required for Wafer Design and PVC solvent weld coupling). When stray currents exist in the pipeline installation of grounding plates up- and downstream of the flowmeter primary is recom-mended.
Connection Cables
In the vicinity of the installation site appropriate suppression mea-sures should be employed, protection diodes, varistors or RC-com-binations, at valves and circuit protectors (VDE 0580).
!Note:The instrument satisfies the requirements of the EMC-Guide-line and the NAMUR-Recommendations NE 21 3/93 “Electro-magnetic Resistance of Equipment in the Process Industries and Laboratories”.
!Note:A water trap should be installed in the cables to the flowmeter primary.
Output SignalAn electronic frequency counter, SPC, PC or Process Control Sys-tem can be connected to the flowrate proportional scaled pulse or the frequency output. Therefore it is possible to integrate the flow-meter system into a batch or fill system as well as into continuous flow processes.
The processing of the pulse output for batch and fill processes must be accomplished in peripheral instrumentation. This includes controlling the system, integrating the flow for actuation of the valves when the fill quantity is reached, measurement of the over-run flow, calculation of the overrun correction and a check of the batch quantity for over- and/or underfills. A low flow cutoff of ap-prox. 1% flowrate can be turned on when required. Alternately, the integrated batch software for a single stage batch cycle can be uti-lized.
There is also a 0/4 - 20 mA current output available in the operating modes “Conti”.
Electrode AxisIn horizontal installations assure that neither of the two electrodes is positioned at the highest point in the system. Gas bubbles which may be present could interrupt the electrical connection between the electrodes and the fluid. The ideal EMF installation is in a ver-tical pipeline. Fig. 7 shows the two preferred installations.
!Warning:The flowmeter primary should not be installed in the vicinity of strong electromagnetic fields. We recommend that shielded connection cables be used. It is advantageous to route the cables in grounded metallic conduits in which a number of cables of the same type can be run together.Excess cable should not be coiled.

Installation Requirements, Flowmeter Primary
Installation in Larger Size PipelinesThe flowmeter primary can be installed in larger size pipeline with-out concerns by utilizing transition fittings (flanged reducers per DIN 28545). The pressure drops resulting from the size reduction can be determined from the diagram in Fig. 8. The procedure for determining the pressure drop is as follows:
1. Calculate the diameter ratio d/D.
2. Calculate the flow velocity as a function of the meter sizeand the flowrate:
v =
The flow velocity can be determined from the Flowrate Nomograph Fig. 6.
3. The pressure drop can be read in Fig. 8 - “Pressure Drop”is read on the y-axis at the intersection of the “Diameter Ratio d/D” value on the x-axis and the flow velocity value.
