The real problem isn’t accuracy. It’s fit.
You’ve run into this:
- The vessel is too small
- The skid is already packed
- The nozzle location isn’t ideal
- There’s no room to install what you normally would
So the workaround becomes:
- Mount it off-angle
- Switch to a less reliable technology
- Or skip measurement entirely
That’s where problems start.
Not because the technology isn’t good—but because it wasn’t designed for the space you have.
What’s changed
The Micropilot FMR43 is built for this exact scenario.
Not a downsized legacy device.
A compact radar level transmitter designed for tight installs.

What that means in practice:
- Compact footprint for small vessels and skids
- High-frequency radar (80 / 180 GHz) for reliable measurement in confined spaces
- Non-contact measurement (no buildup, no intrusion)
- Digital communication (IO-Link / HART) for integration and remote access
Where this fits
- Skids and OEM systems
- Small vessels and tight installations
- Retrofit measurement points
Built on a hygienic design platform for applications where cleanability and compliance matter.
Where this fits best (field reality)
Small tanks and vessels
- Batching systems
- Additive dosing
- R&D or pilot setups
Traditional radar can struggle here.
Guided wave introduces maintenance.
FMR43 gives you stable, non-contact measurement in a small footprint.
Skids and OEM builds
- Space is limited from day one
- Standardization matters
- Commissioning time matters
The compact design + digital comms make it easier to:
- Fit into tight layouts
- Reduce engineering variation
- Speed up startup
Retrofit problem points
These are the spots most plants live with:
- “Good enough” measurement
- Inconsistent readings
- Install constraints no one wants to touch
FMR43 gives you a way to fix the problem without redesigning the system.
What matters to your team
Maintenance
- Less time fighting installs
- Guided setup (Bluetooth / display)
- Fewer repeat issues
Engineering
- One device that fits more applications
- Less compromise on install location
- Reliable performance in small spaces
Operations
- Fewer blind spots in the process
- Reduced risk of downtime
- More consistent measurement
Why this is worth a look
Most measurement issues don’t show up as failures.
They show up as:
- Time lost troubleshooting
- Inconsistent process data
- Workarounds that become permanent
If you have level points that were “hard to install” the first time—those are the ones to revisit.
About the Compact Line
The FMR43 is part of Endress+Hauser’s Compact Line—built for hygienic applications where space, cleanability, and reliability all matter.
- Designed for tight vessels and small process environments
- Standardized across level, point level, and pressure
- Focused on ease of commissioning and maintenance
See if it fits your application
If you have:
- A tight vessel
- A skid with limited space
- A measurement point that’s never been quite right
We can walk through it with you.
