EMFM Electromagnetic Flow Meter-Precision Measurement for Conductive Liquids – Water, Wastewater, Slurries, and Chemical Media
2026-11-05
When You Need Flow Data That Doesn't Drift
Mechanical meters wear. Turbine meters clog. Ultrasonic meters struggle with dirty fluids.
The EMFM has no moving parts – nothing to wear, nothing to clog, nothing to fail.
It measures flow using Faraday's law of electromagnetic induction. The liquid itself acts as the conductor. No obstruction in the flow path. No pressure loss. No maintenance from wear.
Built for the Fluids That Matter
| Your Challenge | EMFM Answer |
|---|---|
| Conductive liquids | Acids, alkalis, salt solutions – no wetted moving parts, corrosion-resistant liners available |
| Wastewater and slurries | No clogging – open flow path handles solids, fibers, and suspended particles |
| Coal slurry, pulp, plaster mortar | Handles suspended solids and viscous media – no obstruction |
| Resin, rubber latex, synthetic fiber pulp | No moving parts to foul – reliable measurement |
| Photosensitive latex | Non-contact measurement – no contamination risk |
| Blood flow and biochemical | Hygienic, non-contact measurement – suitable for medical and pharmaceutical applications |
| Wide flow range | 0.05~12 m/s – low flow to high velocity |
| High accuracy | 0.5% accuracy in the 0.1~10 m/s range – reliable data |
| Wide pipe sizes | DN6 ~ DN2000 – from small tubes to large pipelines |
| Multiple pressure ratings | PN6 ~ PN420 – handles low to high pressure systems |
| Multiple connection types | Flange, clamp, thread – matches your existing piping |
| Multiple output options | 4~20mA, pulse, RS485 (Modbus), HART – connects to any control system |
Why Electromagnetic – Not Mechanical
| Meter Type | Limitation | EMFM Advantage |
|---|---|---|
| Turbine | Wears, clogs, affected by viscosity | No moving parts, no clogging, viscosity-independent |
| Positive displacement | Wears, pressure drop, affected by viscosity | No wear, low pressure drop, viscosity-independent |
| Ultrasonic | Struggles with solids and bubbles | Handles solids, no signal loss from particles |
| Vortex | Requires minimum Reynolds number, pressure drop | Wide range, low pressure drop |
| Coriolis | High cost, pressure drop, size limitations | Lower cost, lower pressure drop, larger sizes available |

One Question
Would you rather replace worn parts – or measure flow with nothing in the way?
Turbines wear. Gear meters clog. Ultrasonic sensors drift.
Electromagnetic measurement leaves the flow path open.
The EMFM gives you the reliability you need.
