selection summary
MV-RD12T is an anti-corrosion 80 GHz radar water level meter, mainly used for liquid measurement, with a reference range of 0.15-50m. It is suitable for urban manhole water levels, rivers, channels, reservoir water levels, pools, aeration tanks and other water treatment conditions. When selecting, you should focus on checking the range, temperature and pressure, connections, materials, output and installation conditions.
Product overview
The integrated 80 GHz radar water level meter with PVDF anti-corrosion housing is suitable for water level monitoring in manholes, rivers, reservoirs and aeration tanks. Low power consumption and RS485 communication are optional.
Measurement principle
MV-RD12T uses 80 GHz frequency modulated continuous wave measurement: the antenna emits a continuous frequency sweep signal and receives the medium surface echo, and the instrument calculates the distance based on the frequency difference between the emission and the echo. The high-frequency narrow beam is beneficial to avoid tank wall components, but it still requires the correct selection of the nozzle location, antenna size and false echo suppression.
Core advantages
- PVDF anti-corrosion shell, IP68, supports 10m water depth for 24 hours protection
- 6° launch angle enables longer range measurement in manholes
- Built-in lens antenna, resistant to rain and condensation
Usage scenarios
- City manhole water level
- Rivers, channels, reservoir water levels
- Water treatment conditions such as pools and aeration tanks

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 media is MV-RD12T mainly suitable for measuring?
MV-RD12T is designed for liquids. Common scenarios include urban manhole water levels, rivers, channels, reservoir water levels, pools, aeration tanks and other water treatment conditions. If there is heavy foam, crystallization, serious hanging or extremely low dielectric constant, the echo conditions should be checked first.
What is the measuring range of MV-RD12T?
The data range of MV-RD12T is 0.15-50m. The selection should be based on the effective range, blind zone, installation height and abnormal high and low positions, and should not be selected based on the total height of the container.
What are the allowed temperatures and pressures of the MV-RD12T?
The reference temperature range of MV-RD12T is -40-80℃, and the reference pressure range is normal pressure. The upper temperature limit and the upper pressure limit cannot be used at the same time by default, and the sealing, flange and explosion-proof configurations need to be confirmed according to the combined process conditions.
How to choose the process connection of MV-RD12T?
MV-RD12T can refer to G2A PVDF; flange ≥ DN50. The final connection should be determined based on the size of the nozzle, the tank structure, the size of the antenna or probe, the maintenance space and the corrosivity of the medium.
Can MV-RD12T be connected to PLC or DCS?
The reference output configuration of MV-RD12T is DC9-28V/RS485 Modbus; DC12-24V/4-20mA+RS485; DC24V/4-20mA/HART; optional 3.6V low power consumption. The power supply, analog or digital protocol, station number, baud rate, as well as isolation and lightning protection requirements should be unified before ordering.
What information do I need to provide when making an inquiry about MV-RD12T?
Inquiries for MV-RD12T require at least medium, range, temperature, pressure, process connection, material, explosion-proof area, power supply, output protocol, on-site photos and container size; for special process conditions, it is recommended to attach process drawings.
