Product catalog
The full RETTAR instrument line for level, volume, density and flow measurement — from non-contact radar to density meters and conveyor belt control systems.
How to choose a device
Do you just need the current level at a single point?
A standard radar level meter (CFR6900 for solids, CFR6400 for liquids) is faster to install and cheaper than a 3D scanner when pile shape doesn't matter.
Do you need an accurate volume/mass of stock in an irregularly shaped bin or warehouse?
A radar or laser 3D scanner (3DPro2300, 3DPro2500) builds a 3D surface model and calculates volume to ±0.5–2% accuracy instead of estimating from a single point.
Do you need a real-time material profile on a conveyor?
A laser profiler or radar 2D scanner (2DPro2100) — monitors distribution and prevents belt overload.
Is the medium an aggressive liquid or highly abrasive slurry?
CFR6400 (non-contact radar) for liquids; for slurry, combine a density meter (including the non-contact radioisotope NRD3000) with a radar level meter.
Do you just need overflow/empty alarms, not continuous measurement?
A microwave or Doppler point level switch is cheaper than a full level meter when only threshold alarming is needed.
