Process Temperature
−10…+70 °C (29 mm saltwater version 0…+50 °C)
Fits HART-enabled hydrostatic level where you need Endress+Hauser Waterpilot FMX21 with 4–20 mA HART 6.0—ceramic cell to 20 bar and fresh/waste/saltwater probe diameters.
Key advantages
- Protocol — 4–20 mA HART 6.0
- Accuracy — ±0.2% reference; ±0.1% Platinum
- Range — 100 mbar…20 bar (~200 m H₂O)
- Cell — Oil-free ceramic
- Media kits — Fresh / waste / saltwater diameters
Typical applications
- SCADA HART level loops.
- Municipal water level.
- Coastal saltwater probing.
Selection guide
- HART host / DD needs
- Medium diameter
- Cable / venting
- Approvals
Common mistakes
- Assuming a legacy FMX16x order code without remapping to FMX21.
- Under-sizing cable for well depth.
- Mixing drinking-water and wastewater materials.
When to RFQ / what to tell us
- Order code intent, cable, HART.
- Quantity, ship-to.
