EMFM Electromagnetic Flow Meter
2026-10-09
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 |
|---|---|
| Corrosive liquids | Acid, alkali, solvent – no wetted moving parts, corrosion-resistant liners available |
| Wastewater and slurries | No clogging – open flow path handles solids and fibers |
| Viscosity changes | No effect – measurement is independent of viscosity |
| Temperature and pressure swings | No effect – measurement is independent of temperature, pressure, and density |
| Bidirectional flow | Measures both forward and reverse flow – ideal for batching and recirculation |
| Dirty fluids | No obstruction – nothing to foul, nothing to clean |
| Hazardous areas | No ignition risk from moving parts – suitable for many hazardous environments |
| Remote monitoring | RS485/MODBUS/HART – integrates with 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 |

| Environmental | Effluent monitoring, discharge compliance | Accurate, reliable, remote communication |
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.
