VEGAPULS C 22 Radar Level Transmitter Overview
VEGAPULS C 22 is a compact radar level transmitter launched by VEGA, suitable for continuous level measurement of liquids and bulk solids. It uses 80 GHz high-frequency technology and features a small beam angle and strong anti-interference capability, making it especially suitable for installation in small tanks or narrow spaces.
This article provides the download of the VEGAPULS C 22 Chinese manual and explains selection, installation, commissioning, and maintenance, targeting engineering technical personnel and procurement personnel.
Core Technology and Main Parameters
VEGAPULS C 22 is based on the 80 GHz frequency modulated continuous wave (FMCW) principle, with measurement accuracy up to ±2 mm. Its housing protection rating is IP66/IP67, suitable for harsh industrial environments.

Installation and Commissioning Steps
Correct installation and commissioning are key to ensuring the measurement stability of the VEGAPULS C 22. The following steps are applicable to most conventional working conditions.
Installation Points
- The installation location should avoid the feed inlet, agitator, and tank wall to prevent false echoes.
- The instrument axis should be perpendicular to the material surface, and the tilt angle is recommended to be less than 3°.
- For flange installation, ensure that the antenna extends beyond the flange surface to avoid nozzle reflection.
- When used outdoors or in humid environments, it is recommended to install a protective cover.
Commissioning Steps
- Power on and confirm that the instrument self-test passes and the output current is within the 4 ~ 20 mA range.
- Connect the instrument via VEGADIS 81 or PC software PACTware.
- Enter the empty tank height (E value) and full tank height (F value), and set the measuring range.
- Execute the false echo suppression function and record the interference echo curve.
- Observe whether the level display matches the actual situation, and fine-tune parameters if necessary.
Common Problems and Maintenance Recommendations
VEGAPULS C 22 is usually maintenance-free, but in high-dust or scaling-prone working conditions, the antenna surface needs to be checked regularly.
- Fluctuating measured value: Check whether there is interference from an agitator or feed flow, and re-execute false echo suppression.
- No signal output: Confirm whether the supply voltage and loop load are within the allowable range.
- Antenna scaling: Wipe with a soft cloth and neutral detergent, avoiding scratching the lens.

Selection and Procurement Recommendations
When purchasing VEGAPULS C 22, it is necessary to confirm the process connection, output signal, and certification requirements. Common options include:
- Process connection: G1½ thread, flange, etc.
- Output: 4 ~ 20 mA / HART.
- Certification: ATEX, IECEx, and other explosion-proof certifications (depending on working conditions).
It is recommended to provide the supplier with the medium name, temperature, pressure, and measuring range to quickly match the model.
