NABL Calibration Service For Water Flow Meters

Service Details

Product Description:The Electromagnetic Flowmeter or Mag Meters are suitable for flow measurement in all kinds of conductive fluids, and it is especially suited for flow measurement of Water, Waste Water, Sludge and other fluids containing particles. The flow meter is easy to install and put to service. Measurement : Electromagnetic flow meters may have either Direct Current (DC) or Alternating 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 because the voltage induced over the electrodes will be a DC voltage. The drawbacks are measurement errors due to electro-chemical polarization between the electrodes and the fluid. The Electromagnetic Flow Meters are excited by a 2.5 Hz square wave and thereby eliminate the drawbacks of both DC and AC systems. A microprocessor receives and measures the amplitude of the pulse with a 16 - bit resolution, and converts and displays the result on the display unit. Working Principle: This is working on the principal of faraday`s law which states that when a conductor moves through a magnetic field of a given strength a voltage is produced in the conductor and proportion to the relative velocity between the conductor and the magnetic field.
