Electromagnetic flow sensor-SN52

The SN52 series electromagnetic flowmeter is a key flow measurement instrument composed of a sensor and a transmitter. It operates based on Faraday’s law of electromagnetic induction and is used to measure conductive liquids or two-phase media. The medium’s conductivity must typically be greater than 5 µS/cm (tap water conductivity is approximately 100–500 µS/cm).

It is suitable for measuring various acidic, alkaline, and saline solutions, as well as pulp, slurry, etc. However, the medium should not contain excessive ferromagnetic substances or large amounts of bubbles.

Widely used in industries such as petroleum, chemical, metallurgy, textile, paper, environmental protection, and food, as well as in municipal utilities and water conservancy for fluid measurement.

Flow Velocity Range: 1...150 cm/s (for water)
No moving parts in the measuring tube; no pressure loss; minimal straight pipe length requirement.

Sensor supports grounding electrode for reliable grounding
Bi-directional flow measurement capability.

Transmitter with LCD and backlight, easily readable in direct sunlight or dark environments.

Transmitter can simultaneously display flow percentage, actual flow, and totalized flow.

Integrated version features a ≤90° rotatable display, improving visibility after installation.

Transmitter includes self-diagnostic alarms, empty pipe detection, high/low flow alarms, and dual flow outputs.
