selection summary
MV-RD12T-120G is a 120 GHz radar level meter used mainly for liquid measurements with a reference range of 0.1-30 m and 0.15-90 m. It is suitable for the water level of urban wells, riverways, channels, reservoirs, reservoirs, exposure and sludge ponds and should be selected with a focus on the scale, temperature, connection, material, output and installation conditions.
Product overview
The 120 GHz radar-level meter for PVDF corrosion-resistant casings, protected by a narrow beam of 5° and an IP68, is suitable for the pits, rivers, reservoirs and water treatment sites.
Measurement principle
MV-RD12T-120G uses 120 GHz FM continuous wave measurements: antennas launch continuous scan signals and receive media surface echoes, and instrumentation calculates distance based on frequency differences between launch and echo. HF narrow beams allow for the avoidance of canned wall components, but still require proper selection of the receiver position, antenna size and completion of false echo suppression.
Core advantages
- 120 GHz HF measurements with a maximum range of 90 m
- PVDF corrosion-resistant shell, IP68 protection
- 5° narrow beams, inner lens antennas resistant to rain condensation
Usage scenarios
- City manhole water level
- Rivers, channels, reservoir water levels
- Water, air and sludge ponds

Selection guide
- Confirm whether the medium is liquid or solid, and provide dielectric properties, dust, foam, steam and stirring conditions.
- Check the beam angle and antenna size according to the effective range, installation nozzle, tank internal components and material surface shape.
- Temperature, pressure, corrosiveness and explosion-proof requirements must be checked in combination, not just the upper limit of a single item.
- Confirm process connection, power supply, output protocol, on-site display, Bluetooth commissioning and shell material.
Key points for installation and commissioning
- The antenna should be aimed vertically at the surface of the medium as much as possible, avoiding the feed inlet, agitator, ladders and reinforcement ribs.
- The diameter and length of the installed nozzle should match the antenna/beam, and false echo suppression should be performed if necessary.
- During commissioning, enter the empty height, full position, media type and response speed, and review them once at the low position and the high position.
Procurement and Technical Confirmation Checklist
- Media name, density/dielectric properties, corrosiveness, and foam, vapor, dust, crystallization or material buildup.
- Container/channel dimensions, normal and extreme ranges, installation location, nozzle or bracket dimensions, internal components and on-site photos.
- Process temperature and pressure combinations, wetted materials, sealing, protection, explosion-proof areas and ambient temperature.
- Power supply, output protocol, wire system, display/commissioning method, control system interface and accessory requirements.
- It is recommended to check the arrival acceptance: nameplate model, process connection, measuring range, material, power supply output, explosion-proof certificate and random documents.
FAQ
What medium does MV-RD12T-120G typically measure?
MV-RD12T-120G is liquid-oriented and common scenarios include urban well water levels, riverways, channels, reservoir water levels, pools, exposed air and sludge pools. In the case of thick foams, crystals, heavy hangers or very low medium constants, the echo conditions should be checked first.
What's the MV-RD12T-120G scale?
MV-RD12T-120G information range 0.1-30 m; 0.15-90m. The selected type shall be retained at the mass range, blind zone, installation height and abnormally high low level and shall not be selected only by the total height of the packaging.
What are the temperatures and pressures allowed for MV-RD12T-120G?
The reference temperature range for MV-RD12T-120G is -40-80°C and the reference pressure range is constant. Temperature ceilings cannot be used by default at the same time as pressure ceilings, and seals, flanges and explosion-proof configurations need to be confirmed by combination.
How do you choose the MV-RD12T-120G process connection?
MV-RD12T-120G, see G2A PVDF; François DN50. The final connection shall be determined in conjunction with the receiver size, tank structure, antenna or probe size, maintenance space and medium corrosivity.
Could MV-RD12T-120G access PLC or DCS?
The reference output configuration of MV-RD12T-120G is DC9-28V/RS485 Modbus; DC12-24V/4-20mA+RS485; DC24V/4-20mA/HART; option 3.6V low power. Power supply, analogue or numerical protocols, station numbers, Porter rates, and quarantine and mine protection requirements shall be unified prior to ordering.
What information is required for the request for MV-RD12T-120G?
The request for MV-RD12T-120G requires at least medium, scale, temperature, pressure, process connection, materials, explosion-proof areas, power supply, output protocols, site photographs and container sizes; special work proposals are accompanied by process maps.
