MV-RD13G Ultra-High-Temperature 80 GHz Radar Level Meter

selection summary

MV-RD13G is an ultra-high temperature 80 GHz radar level meter, mainly used for liquid/solid measurement. The reference range is 0.1-30m; 0.2-150m. It is suitable for refining high-temperature mixing tanks, hot asphalt, raw materials that react chemically with PTFE, and high-temperature chemical process containers. When selecting, you should focus on checking the range, temperature and pressure, connections, materials, output and installation conditions.

Product overview

Ultra-high temperature 80 GHz radar level meter using 76mm PEEK lens antenna, suitable for high temperature, pressure resistant and chemical process media where PTFE is not suitable.

Measurement principle

MV-RD13G 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

PEEK lens antenna has better pressure resistance than conventional PTFE structure
Long-term temperature resistance of 260℃, short-term temperature resistance of 300℃
3° narrow beam, suitable for complex high temperature vessels

Usage scenarios

Refining high temperature mixing tank, hot asphalt
Raw materials that chemically react with PTFE
High temperature chemical process vessels

application benefits

Procurement concernThe antenna, process connection, high temperature structure and output options of MV-RD13G will affect the delivery time and price. The inquiry form should state the actual process conditions instead of just the measuring range.

technical valueThe narrow beam helps reduce interference caused by tank walls, ladders and stirrers, making it suitable for small interfaces or complex containers; the correct installation position is still a prerequisite for stable measurement.

Operation and maintenance valueNon-contact measurement reduces wear and contamination of wetted parts, and echoes from empty tanks, high positions and typical process conditions are saved during commissioning to facilitate subsequent diagnosis.

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.

specification range:Careful confirmation is required: thick foam, strong steam or condensation, serious accumulation of material at the antenna port, too long and too narrow pipe, and the installation point is facing the feed flow. When these conditions occur, the echo path should be checked first or site drawings provided.

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-RD13G mainly suitable for measuring?

MV-RD13G is designed for liquids/solids. Common scenarios include refining high-temperature mixing tanks, hot asphalt, raw materials that react chemically with PTFE, and high-temperature chemical process containers. 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-RD13G?

The data range of MV-RD13G is 0.1-30m; 0.2-150m. 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-RD13G?

The reference temperature range of MV-RD13G is -25-260℃ (long-term); -25-300℃ (short-term), and the reference pressure range is -0.1-2.5MPa. 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-RD13G?

MV-RD13G can refer to stainless steel lined PEEK flange ≥ DN80. 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-RD13G be connected to PLC or DCS?

The reference output configuration of MV-RD13G is two-wire DC24V / 4-20mA / HART; optional four-wire AC220V, RS485/Modbus, dual relay, FF, PROFIBUS-PA/DP. 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-RD13G?

Inquiries for MV-RD13G 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.
