Electromagnetic Flow Meter

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

The NGET’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.

Features

High precision: Often within 0.5% of the reading.
Broad Measuring Range: With a measuring range of 0.2 m3/h to 1300 m3/h, this device is suitable
for 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 (IS/IEC 60079-0: 2004)

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.
