Stable and reliable:   No mechanical moving parts, reducing wear and maintenance needs; adopting IP65 or higher protection rating , suitable for laboratory and light industrial environments.

Brief Overview of How It Works

It operates on the same principle as all electromagnetic flowmeters: The excitation coil inside the instrument generates a working magnetic field. As conductive liquid flows through the measuring tube, it cuts across the magnetic field lines, inducing an electromotive force proportional to the flow velocity. This signal is detected by the measuring electrodes, amplified and processed by the converter, and finally outputted as a standard flow signal.

Key Points for Selection and Installation

Clearly define the medium characteristics:   Electrical conductivity ( Must be ≥ the minimum value required by the instrument, typically 5 μS/cm ）、temperature, pressure, viscosity, corrosivity, and whether or not it contains particulates.

Precise traffic range:   Determine the minimum, typical, and maximum flow rates to ensure that the selected model meets the requirements and operates within the optimal precision range.

Health requirements:   When applying to food and pharmaceutical industries, be sure to select models with appropriate hygiene certifications and materials (such as PTFE/PFA-lined or polished 316L electrodes).

Strict installation requirements:

Guaranteed full pipe:   This is an absolute prerequisite for precise measurement; vertical or upward-tilted installation is recommended.

Sufficient straight pipe section:   Ensure there is sufficient straight pipe length both upstream and downstream of the instrument (typically 5D upstream and 3D downstream, where D represents the pipe diameter—refer to the manual for specific guidelines) to achieve a stable flow condition.

Avoid bubbles and vibrations:   The installation location should avoid bubble accumulation and strong vibration sources.

Professional Grounding:   Good grounding is essential for signal stability and noise immunity, and must be performed according to specifications.
