Corrosion-Resistant Radar Level Meter: Review the Complete Assembly2026-08-09Corrosion resistance belongs to the complete radar assembly, not the antenna alone. Map liquid, vapour, joint and exterior exposure before choosing MV-RD901 or MV-RD702. -
High-Temperature High-Pressure Radar Selection: Confirm Operating Pairs2026-08-09Pressure and temperature maxima from radar options cannot be combined. Specify MV-RD705 with simultaneous operating pairs and verify the probe, seal and joint together. -
Radar Installation in Bulk-Solids Silos: Approve the Roof Layout First2026-08-09A convenient silo roof opening may observe the filling stream rather than stock. Check MV-RD21 beam clearance, pile movement and first-cycle evidence before fabrication. -
Weak Radar Echoes in Liquid Tanks: Separate Reflection, Foam and Deposits2026-08-09Weak echoes do not always mean foam. Use MV-RD12 diagnostics and a safe level reference to separate low reflection, deposits and process-state changes before replacement. -
False Echoes in Radar Level Measurement: Diagnose Before Mapping2026-08-09A wrong radar level can come from an echo, a datum or PLC scaling. Diagnose MV-RD21 with curves and independent surface evidence before changing suppression or damping.
-
Guided Wave Radar Probe Selection: Rod, Cable or Coaxial Construction2026-08-09A guided wave probe must fit the vessel and its handling route. Compare MV-RD701 rod or cable with MV-RD704 coaxial construction before checking range and service access. -
FMCW Radar Level Meter: From Beat Frequency to a Valid Process Value2026-08-09FMCW radar derives distance before level is calculated. Trace MV-RD12 echo selection, settings and PLC scaling to isolate faults without confusing frequency with range.
-
80 GHz vs 26 GHz Radar: Compare MV-RD21 and MV-RD903 for Solids2026-08-09Compare MV-RD21 and MV-RD903 for the same solids duty. Check antenna fit, beam clearance, range and mounting before selecting 80 GHz or 26 GHz radar for a silo.
