Fits hydrostatic level RFQs listing Endress+Hauser Waterpilot FMX23—probe-style Waterpilot family sensing for water/wastewater. Confirm the exact FMX23 measuring cell, ranges, and approvals against the current E+H TI before purchase.
Key advantages
- Family — Waterpilot hydrostatic probe line (FMX11 / FMX21 documented siblings)
- Principle — Hydrostatic pressure level measurement
- Output class — Typically 4–20 mA two-wire (confirm FMX23 order code)
- Media — Water / wastewater applications (confirm wetted materials)
- Selection tip — Match FMX23 TI to depth, medium, and approvals
Typical applications
- Water level RFQs specifying FMX23.
- Wastewater hydrostatic replacements.
- Projects migrating within Waterpilot family.
Selection guide
- Verify TI / order code
- Depth / pressure range
- Cable / Ex
- Compare FMX11 vs FMX21 if FMX23 unavailable
Common mistakes
- Assuming FMX21 ranges apply unchanged to FMX23.
- Skipping current TI verification.
- Ordering without medium/approval codes.
When to RFQ / what to tell us
- Exact order code or TI revision.
- Depth, medium, cable, approvals, quantity, ship-to.
