Working Principle and Main Features
Ultrasonic Measurement Principle
The VEGASON 61 emits ultrasonic pulses through the transducer. The sound waves reflect off the material surface and return to the transducer. The instrument calculates the level distance based on the time difference between transmission and reception.
This principle achieves non-contact measurement, is not affected by medium density, viscosity, and other parameters, and is suitable for corrosive liquids and powdered solids.
Core Features
- Non-contact measurement: no wear, maintenance-free, suitable for applications with high hygiene requirements.
- Wide measuring range: maximum range up to 15 m (depending on model and working conditions).
- Flexible output signals: supports 4...20 mA/HART and other output methods.
- Easy commissioning: parameters can be set via display module or PC software.

Installation Steps and Precautions
Installation Steps
- Confirm the installation position: avoid the inlet, agitator, and tank wall, and ensure there are no obstructions within the sound beam cone.
- Install the flange or threaded connection: tighten according to the torque requirements in the manual to ensure sealing.
- Adjust the instrument orientation: make the transducer perpendicular to the material surface.
- Connect the cable: connect the power and signal lines according to the wiring diagram, and pay attention to shielding layer grounding.
- Power-on check: observe whether the display module starts normally.
Installation Precautions
- Avoid installation in acoustic interference areas, such as places with foam, steam, or dense dust.
- Ensure there is no material within the dead zone, otherwise measurement errors will occur.
- For outdoor installation, a sunshade should be added to prevent high-temperature effects.
Commissioning and Parameter Setting
The VEGASON 61 supports commissioning via the display module or VEGACONNECT software. The basic steps include:
- Enter the empty tank height (distance from the flange face to the tank bottom).
- Set the full scale (distance corresponding to 100% level).
- Select the medium type (liquid or solid) to optimize signal processing.
- Adjust the damping time according to working conditions to suppress fluctuations.
- Save parameters and exit commissioning mode.
After commissioning is completed, it is recommended to perform multiple actual level comparisons to confirm measurement linearity.
Common Faults and Troubleshooting Methods
| Fault Symptom | Possible Cause | Troubleshooting Method |
|---|---|---|
| No display | Abnormal power supply | Check power supply voltage and wiring |
| Measured value jumps | Acoustic interference | Adjust installation position or increase damping |
| Measured value remains constant | Material in dead zone | Lower installation position or increase dead zone setting |
| Abnormal output current | Incorrect parameter setting | Recalibrate the range |
Maintenance and Care Recommendations
- Regularly check the transducer surface and remove dust or scaling.
- Calibrate the output current every 6 months.
- After long-term shutdown and restart, re-calibrate the empty tank and full tank.
Following the above maintenance measures can extend the service life of the VEGASON 61 and maintain measurement accuracy.
Summary
With non-contact measurement, wide range, and flexible output, the VEGASON 61 ultrasonic level transmitter is a reliable choice for industrial level measurement. Correct installation, commissioning, and maintenance are the keys to ensuring its long-term stable operation. For complete information, please download the VEGASON 61 Chinese manual.
