VE/801 Series High Precision Electromagnetic Flowmeter

Product introduction

The VE801 Series operates based on Faraday’s Law of Electromagnetic Induction. When a conductive liquid flows through a magnetic field generated within the flow tube, an electric voltage is induced perpendicular to the flow direction. This induced voltage is directly proportional to the volumetric flow rate and is measured by electrodes placed along the pipe wall.

Physical Properties

★ Non-Intrusive Flow Measurement
No internal moving parts or flow obstructions — ensures zero pressure loss and allows for reliable measurement of abrasive or corrosive liquids.

★ Independent of Fluid Properties
Accurate flow measurement unaffected by fluid density, viscosity, temperature, or flow profile — ideal for heterogeneous or variable media.

★ Wide Range & High Linearity
Maintains excellent linearity and stability across a broad range of flow rates, from low velocity dosing to high-capacity pipelines.

★ Chemical & Abrasion Resistance
Multiple liner materials (e.g., PTFE, PFA, rubber) available to resist acids, alkalis, slurries, and aggressive process fluids.

★ Digital Communication Options
Supports HART, Modbus, PROFIBUS, and 4–20 mA outputs — seamless integration with PLCs, DCS, and SCADA systems.Bluetooth and Wi-Fi are available on specific models.

★ Bi-Directional Measurement
Capable of measuring flow in both directions with equal accuracy — supports advanced diagnostics and redundancy in loop systems.

VE Electromagnetic Flowmeter Industry knowledge

The electromagnetic flowmeter operates based on Faraday's Law of Induction, which states that an electromotive force(EMF) is induced in a conductor when it moves through a magnetic field. This measurement principle can be applied to conductive fluids. When such a fluid flows through a pipe perpendicular to the direction of a magnetic field, an induced EMF is generated in the fluid. This induced EMF can be measured using two symmetrically placed electrodes.

The signal voltage Ue is directly proportional to the magnetic flux density B, the distance between the electrodes D, and the average velocity of the fluid V. Since the magnetic flux density B and the distance between the electrodes D are constants, the signal voltage Ue is directly proportional to the average flow velocity V.
The equation used to calculate the volumetric flow rate indicates that the signal voltage Ue is linearly proportional to the volumetric flow rate.
The induced signal voltage is converted into scaled, analog, as well as digital output signals in the converter.
