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

Measurement principleInstallation guidelines

≥ 10 DN

≥ 3 DN≥ 5 DN

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



Never install it in an upper pipe elbow or

descending pipeline

Do not install directly in front of a free outlet



Avoid vacuum, cavitation and gas bubbles

Avoid external influences (such as magnetic sources and vibrations)

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.

Measurement principleCalibration

Piston prover

− DN 2.5 to DN 150

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


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

Drainage

Ruler on piston rod

Measurement principleCalibrating with a calibration tower

The uncertainty of these KROHNE calibration towers is

significantly less than the error limits of the measuring devices to

be tested

RvA accreditation by NMi

Traceability to international standards

Nominal size DN 3000 or 120 inches

Maximum flow rate: 30,000 m³/h

Uncertainty: 0.013%
