Technical Articles
This section focuses on radar level meters, level switches, weigh modules, weighing indicators and industrial data acquisition, sorting out knowledge on principles, selection, installation.
-
Radar Level to Volume Conversion: Tank Geometry and Calculation Tests2026-08-10Level becomes volume only through a verified tank model. Use MV-RD12 distance with a consistent datum, test horizontal-tank geometry and retain the raw value for audit. -
Bulk-Solids Radar Selection: Reflection, Pile Shape and Filling Conditions2026-08-10Bulk density is not a reflection specification. Select MV-RD21 from material state, pile geometry, dust and a representative echo trial at the required distance. -
Radar False-Echo Mapping: Hold Points and Surface-Tracking Tests2026-08-10False-echo mapping can hide the liquid return if learning conditions are wrong. For MV-RD12, preserve the curve, identify the reflector and retest surface tracking.
-
Outdoor Radar Level Meter Protection: Entries, Heat and Signal Circuits2026-08-10Outdoor radar protection depends on glands, cable routes, heat and the housing. Specify the MV-RD12 assembly and verify water paths, signal circuits and access on site.
-
Radar Hazardous-Area Markings: Verify the Offered Configuration2026-08-10An Ex label alone cannot approve a radar for a classified area. Match the exact assembly, marking and certificate conditions to the site before accepting the quotation.
-
Radar Thermal Extension: Insulation Boundaries and Cooling Checks2026-08-10Insulating over a cooling section can raise electronics temperature. Show the MV-RD12G insulation boundary, hot surfaces and air clearance on the installation drawing. -
Radar Antenna Condensation: Separate Moisture, Coating and Heat Problems2026-08-10Moisture on an antenna, process coating and housing water ingress need distinct repairs. Inspect MV-RD12G nozzle drainage, heat path and echo changes before intervention.
-
Radar Nozzle Geometry: Bore, Length and Installed Antenna Position2026-08-10A radar can fit an existing flange yet read a fixed nozzle echo. Compare MV-RD12 and MV-RD13 antenna positions, clear bore and vessel internals on an as-built section.
-
Radar Process Connection Selection: Threads, Flanges and Brackets2026-08-10A matching thread or flange does not prove a radar installation. Specify MV-RD11S or MV-RD12 joint details, antenna position and support on an assembled vessel drawing.
