Endress+Hauser Promag 50 Electromagnetic Flow Meter
Model: Promag 50
The Endress+Hauser Promag 50 electromagnetic flow meter operates on Faraday's law of induction with no moving parts. This design minimizes maintenance and suits liquids with suspended solids, acids, alkalis, and wastewater. It covers 0–10 m/s flow velocity across DN15–DN600 pipe sizes with output signals including 4–20 mA HART and pulse. Standard in Thai water supply, wastewater, food, pharma, and chemical industries requiring reliable, traceable flow measurement.

Frequently Asked Questions
How often should an electromagnetic flow meter be calibrated?+
Typically every 2–5 years depending on process requirements. FDA/GMP pharmaceutical processes often mandate annual calibration or recalibration after any maintenance that affects the sensor.
Why choose electromagnetic over ultrasonic or turbine?+
Electromagnetic suits contaminated liquids, acids, alkalis, and slurries because it has no moving parts. It cannot measure hydrocarbons (oil, gas) — those require Coriolis or vortex meters.
What is the minimum conductivity requirement?+
Promag 50 requires ≥ 5 µS/cm fluid conductivity. Distilled water, RO water, or oils (below this threshold) cannot be measured — use Coriolis or ultrasonic meters instead.
