Choose the right instrument from the KROHNE radar family on our krohne optiwave 5200 product page: FMCW non-contact measurement of liquids, pastes and corrosive media up to 98.4 ft (30 m), SIL2-compliant to IEC 61508, with PP or PTFE wave horn antennas and backwards compatibility with all BM 70x flange systems. If you are specifying a krohne radar level meter for a chemical, pharmaceutical, water treatment or power project, the application triage, model ladder and spec table below show what decides the order — then send your process data for a model recommendation and quote.
Pick the condition that matches your vessel, silo or installed device and jump straight to the specs and next step that decide it.
Liquids and pastes, solid applications and the wider KROHNE line are not interchangeable. These cards set out the headline facts of each family before you compare the detail.
Both are non-contact FMCW instruments, but they are aimed at different contents. Everything below is the published position of each listing — nothing is inferred.
| Specification | OPTIWAVE 5200C/FLiquids, pastes, corrosive media | OPTIWAVE 6300Solid applications |
|---|---|---|
| Measurement technology | FMCW radar, non-contact | FMCW radar level transmitter, non-contact |
| Max measuring range | Up to 98.4 ft (30 m) | See the 6300 listing |
| Media suitability | Liquids and pastes, including corrosive products and aggressive paste materials | Solid applications |
| Antenna / process material | PP (polypropylene) or PTFE (polytetrafluoroethylene) wave horn antennas | See the 6300 listing |
| Measured variables | Distance, level and volume | Level, per the 6300 listing |

| Calibration | Each device calibrated on dedicated calibration rigs before it leaves the factory | See the 6300 listing |
Where the table says “See the 6300 listing”, that figure is published on the OPTIWAVE 6300 product page rather than on this one. Open it, or ask an engineer for the current datasheet of either model.
Four common buying situations, the specifications that actually change the order, and what to do next. Confirm each line with the engineering team before you release a purchase order.
Send the chemistry so the wave horn material is confirmed against your specific product.
Open the 6300 page or ask for a model comparison against the 5200C/F.
Request a configuration matched to your cleaning and documentation needs.
Read the flange-swap explainer and bring your flange details to the enquiry form.
Range, antenna material and flange continuity are where most level-meter projects stall. Each one is explained below, and each one ends in the same place: the data you send with your enquiry.
The OPTIWAVE 5200C/F is specified for a measuring range of up to 98.4 ft (30 m). Treat that as the ceiling, not the guaranteed working span: foam, condensation, nozzle height and vessel shape — a tall narrow tank behaves differently from a wide flat one — all reduce the usable range. Send a simple sketch with tank height, nozzle length and the highest and lowest levels you need, and range can be matched to geometry instead of a headline figure.
Both PP (polypropylene) and PTFE (polytetrafluoroethylene) wave horn antennas are offered, and both are listed for measuring corrosive products. The choice is chemical rather than cosmetic: give the medium, its concentration and the process temperature so the antenna material can be confirmed against that specific chemistry. Because the measurement is non-contact, the antenna never touches the product, which keeps build-up, cleaning and contamination off the wetted-part list entirely.
The converter is backwards compatible with all BM 70x flange systems, which is what makes a like-for-like replacement practical: in most cases the existing flange stays on the nozzle and only the electronics and antenna are replaced. Check two things before you commit — the flange standard and rating currently installed, and the housing position your installation needs, since the housing can sit horizontally or vertically with 360° rotation and the bayonet cover opens without removing the housing.
Confirm your flange standard → through the enquiry form below.
The faster the process data arrives, the faster the model, antenna and flange can be pinned down. One tag or a full project list — both work.
Send these seven points and the engineering team replies with a recommended model, antenna material and a quote for your project quantity.

It is a non-contact FMCW radar level meter that measures distance, level and volume of liquids and pastes, including corrosive products and aggressive paste materials. The product page lists chemical, pharmaceutical, water treatment and power as application industries.
The stated measuring range is up to 98.4 ft (30 m). Tank height, nozzle position and the geometry around the antenna all affect how much of that range is usable, so send a simple tank sketch with your enquiry.
Both PP (polypropylene) and PTFE (polytetrafluoroethylene) wave horn antennas are offered, and both are listed for measuring corrosive products. Share the medium and its concentration so the antenna material can be confirmed against your specific chemical and process temperature.
The converter is backwards compatible with all BM 70x flange systems, so the existing flange can normally stay on the nozzle while the electronics and antenna are replaced. Confirm your flange standard and rating with the team before ordering.
The unit is SIL2-compliant according to IEC 61508. Each device is also calibrated on dedicated calibration rigs before it leaves the factory, and calibration documentation can be requested with your order.
Send the medium, concentration, process temperature and pressure, tank or silo height and nozzle, required approvals, SIL requirement and existing flange standard through the contact page. The engineering team replies with a recommended model and a quote.
