Calibration of a Giant 10 feet Electromagnetic Flowmeter | KROHNE

Here you can witness the class one water calibration of a DN2400 / 96" electromagnetic flowmeter. This sort of application is used for water catchment. More precisely, it is an OPTIFLUX 2300 at the calibration rig at KROHNE Altometer in Dordrecht, The Netherlands. Learn more about calibration at KROHNE: http://krohne.com/en/company/calibrat... If you buy a KROHNE product, you will get a measuring device that performs most accurate with low uncertainty under real process conditions. To achieve this, we operate more than 120 calibration facilities for volume flow, mass flow, level, temperature, density and pressure to (wet-) calibrate any device we manufacture. For example, every flowmeter is wet-calibrated using water or air as standard before leaving our facilities. We can also provide customer specific calibration such as: Carry out multipoint calibrations Vary different parameters such as temperatures, viscosities, pressures etc. Use the actual medium or similar Build or emulate customer-specific flow geometries Use piping provided by the customer For calibration we only use direct comparison of measurands (e.g. for calibration our Coriolis mass flowmeter we use a gravimetric weighing system). Our calibration rigs for our flowmeters are the most accurate used in measuring device production worldwide: the accuracy of the reference is usually 5 to10 times better than that of the flowmeter under test for calibration. This goes for small as well as for very large size flowmeter calibration: KROHNE operates the world’s most precise volumetric calibration rig for flowmeters up to DN 3000 (120"*) with a certified accuracy of 0.013 %. The reference vessel is a 44 m (144 ft*) high tank containing almost ½ million litres (132,000 gal*) of water which allows for a maximum flow rate of 30,000 m³/h (7,925,000 gal/h*). Our meters can be calibrated and certified according to various standards such as OIML, API, Measurement Instruments Directive (MI 001, 002, 004, 005), GOST, etc. All our calibration facilities comply to the traceability requirements according the ISO 17025. Regular inspections by national metrology institutes, round robin tests and alignments with national and international metrological standards according to ISO 9000 and EN 45000 guarantee the quality and comparability of our calibration rigs. Staff performing the calibrations are trained and given regular re-trainings to ensure quality and continuity.
