01
Transmit an ultrasonic pulseThe connected DU sensor sends an acoustic pulse toward the material surface.
|
02
Evaluate returning echoesThe transmitter filters fittings, multiple reflections and sporadic echoes.
|
|
03
Calculate level or volumeEcho travel time is converted into a measured level and optional vessel volume.
|
04
Deliver process outputsAnalog signals and adjustable relays report measurement and alarm states.

| Direct commissioningFMU671 can be calibrated from its front panel. | False-echo suppressionStored envelope data helps ignore fixed vessel structures. | Flexible supervisionIt operates stand-alone or through Rackbus supervisory links. |
| 01 | Which vessels can FMU671 measure without contacting the material? | It supports liquids and solids in vessels of varied shapes when paired with an approved DU sensor. |
| 02 | How does FMU671 reject echoes from vessel fittings? | Fixed-target suppression raises the detection threshold around stored interference echoes. |
| 03 | What analog signals can FMU671 provide? | The outputs are selectable between 0/4 to 20 mA and 0/2 to 10 V. |
| 04 | How many vessel-linearization points does FMU671 store? | The official technical information states up to 30 reference points. |
| 05 | Which supply range is required by FMU671? | Use 20 to 30 V DC around the nominal 24 V DC supply. |
| 06 | What should be recorded before exchanging FMU671? | Save the DU sensor type, calibration, vessel curve, output range, relay thresholds and fail-safe action. |
