Measurement principleIntroduction to electromagnetic flowmeters
EMF = ElectroMagnetic Flowmeter or often referred to as a magmeter or MID?
Used in virtually any industry and for a very wide range of applications
Popular solution for measuring liquid flows from
Liquids with/without solids contents
Drinking water
Slurries & sludges
Chemicals
Pulps & pastes
Constraint:
Liquids with a minimum electrical conductivity
So no oil, gas, steam, or demineralised water

Control valve behind the measuring deviceFor clean water applications where a straight inlet of 5 DN or 3 DN
outlet is unavoidable, a special electromagnetic flowmeter without
straight inlet or outlet runs can be selected

This design requires a specially designed sensor.
With potential differences between the product
and earth, equalising currents may occur
and electrolytically damage the grounding
electrodes
One grounding electrode is directly connected to
the sensor housing.

Calibration rig
− DN 200 to DN 3000
Calibration with water
− Changes to the properties caused by pressure are negligible
− Influences of temperature differences are known
Calibration at reference conditions
All calibration rigs with flow straighteners, for stable, fully developed flow profiles
21 | Introduction to KROHNE EMF
Measurement principleCalibration with a piston prover
A known volume of water is "pressed" through the measuring device,
performed by the computer
When successful:
− Calibration certificate is issued
Two deciding factors are at play when using piston provers
− The diameter of the cylinder
− The position of the piston displacing the water
The displaced volume is calculated using the inner diameter of the cylinder
and the measured movement
For sizes up to DN 300
Accuracy of the calibration rig: 10 times more accurate
than the measuring device to be calibrated Filling and degassing
