Best Suited for Conductive Liquids, Acids, Alkalies,
Water, Pulps, and Slurries

The Infinity Equipment’s Electromagnetic Flow Meter is a highly advanced and dependable instrument, specifically designed to accurately measure flow rates in conductive liquids, acids, alkalies, water, pulps, and slurries. For various industrial applications, the flow meter provides a maintenance free solution with an unparalleled blend of performance, flexibility, and cost-effectiveness. Its non-intrusive design makes it perfect for applications where contamination is a problem because it doesn’t require any contact with the fluid. It also has a high degree of accuracy, typically within 0.5% of full scale.

Working Principle

In Electromagnetic Flow Meter, the magnetic field is generated by a set of coils. As the conductive liquid passes through the electromagnetic field, an electric voltage is induced in the liquid which is directly proportional to its velocity. The induced voltage is perpendicular to both the liquid flow direction and the electromagnetic field direction.

Benefits

  • No Pressure Drop: Electromagnetic flow
    meters use less energy since they don’t cause
    a pressure drop, in contrast to conventional
    flow meters.
  • Low total cost of ownership due to low
    maintenance requirements and lengthy
    operational life.
  • Versatility: Due to its great flexibility and
    broad measuring range, it is appropriate for a
    diverse variety of applications like acidic
    chemicals, corrosive liquids, wastewater,
    cold/warm/hot water; and industries like food
    processing, pharmaceuticals, power generation
    industries, textile industries, pulp and paper
    industries, etc.
  • Eliminates the risk of contamination.
  • Outstanding value relative to performance

Key Features

  • High precision: Often within 0.5% of the reading.
  • Broad Measuring Range: With a measuring range
    a wide range of applications.
  • No moving parts: Non-invasive measurement
    techniques guarantee excellent dependability.
  • Universal Power Supply: 85 V AC-270 V AC, 50 Hz-
    60 Hz/ 24 V DC.
  • Bidirectional measurements: Measurements
    that can be made in both directions—forward and
    backward.
  • Designed for tough settings and highly corrosive
    or abrasive liquids, this material is resistant to
    wear and tear.
  • Unaffected by fluid characteristics: The flow
    meter’s measurement accuracy is unaffected by
    variations in the temperature, pressure, density, or
    viscosity of the fluid.
  • Flameproof (IS/IEC 60079-1:2007)/
    Weatherproof/ Can function in Potentially
    Explosive Atmosphere

Note: Responsibility for the choice of the lining and electrode materials (abrasion and corrosion resistance) lies with the purchaser; the effect of any change in the process medium during the operation of the meter should be considered. Incorrect selection of the lining and/or electrode could lead to a failure of the meter.
*Can be customized.

Options and Customization:

  • Lining Material: Options for various lining materials are available to meet a range of application requirements (e.g., PTFE, hard rubber, polyurethane).
  • Process Connection: Numerous flange choices are available for various process connections/ Multiple electrode materials are available to suit different process fluids.
  • Display Options: Local/Integral or remote displays are offered depending on the installation requirements.
  • Output Options: Multiple output options are available, including 4-20 mA, pulse, and RS485.

Installation Instructions:

The application and the customer’s requirements will determine the precise installation procedure.

  • Orientation: The flow-meter can be put in any direction, although for optimal results, horizontal installation is advised.
    U-bend is ideal for these flow-meters. Refer to the installation manual for details.
  • Pipe Conditions: For precise measurements, make sure the pipe is continually filled with liquid.
  • These meters are also susceptible to damage from lightning strikes if installed outside without canopy.

Upkeep and Calibration:

  • Maintenance: Because there aren’t any moving parts, little maintenance is needed. The only maintenance typically required is cleaning the electrodes and sensor. Nonetheless, it is advised to perform regular check-ups on the electronic components. However, deposits developing on the electrodes, air in the liquid, turbulence, and to some extent water pounding can all influence the accuracy of electromagnetic meters (Pressure transients).
  • Calibration: Regular calibration guarantees the best results. To find out the recommended calibration intervals, contact the manufacturer.
