Electromagnetic vs Ultrasonic Flow Meter: B2B Comparison
Choose electromagnetic flow for conductive liquids and ±0.5% FS accuracy. Choose clamp-on ultrasonic when pipe cutting or process shutdown is not acceptable.
Comparison at a Glance
Published values below come from the current AccuMeasure product specifications. Final configuration depends on the medium, installation, output, and certification.
| Decision point | AM-EMF100 Electromagnetic Flow Meter | AM-UF200 Ultrasonic Flow Meter | Buyer guidance |
|---|---|---|---|
| Starting price | $280 FOB Xi'an | $280 FOB Xi'an | Confirm configuration and freight in the formal quote. |
| MOQ / lead time | 5 units / 15-20 days | 5 units / 15-20 days | One sample is available before a bulk order. |
| Measurement principle | Full-bore electromagnetic | Clamp-on transit-time ultrasonic | Fluid conductivity and installation access are the first decision points. |
| Published pipe size | DN6-DN600 | DN15-DN1000 | Ultrasonic covers larger existing pipes; electromagnetic starts at smaller diameters. |
| Published accuracy | ±0.5% FS | ±1% FS | Use electromagnetic when the tighter published accuracy is required. |
| Fluid requirement | Conductive liquids | Liquids that transmit sound, including oils and pure water | Do not specify an electromagnetic meter for non-conductive oil or ultrapure water. |
| Installation | Inline meter with liner and electrodes | External clamp-on sensors | Clamp-on ultrasonic avoids pipe cutting and process shutdown. |
| Hazardous-area option | ATEX option published | No ATEX claim published | Confirm the exact area classification before quoting either model. |
Choose AM-EMF100 when...
- The liquid is conductive water, wastewater, slurry, or a compatible chemical.
- You need the published ±0.5% FS accuracy.
- An inline installation and process connection are acceptable.
Choose AM-UF200 when...
- The pipe cannot be cut or the process cannot be stopped.
- The fluid is non-conductive but can transmit ultrasound.
- You need portable surveys or coverage up to DN1000.

Buyer FAQ
Can an electromagnetic flow meter measure oil?
Usually no. Electromagnetic meters require a conductive liquid. For oil or another non-conductive fluid that transmits sound, a clamp-on ultrasonic flow meter is the better starting point.
Which flow meter is easier to retrofit?
A clamp-on ultrasonic meter is easier to retrofit because its sensors mount outside the pipe, without cutting the pipe or stopping the process.
Do the two models have different starting prices or MOQ?
AM-EMF100 and AM-UF200 both start at $280 FOB Xi'an, with a published bulk MOQ of 5 units and a standard lead time of 15-20 days.
