High-temperature and high-pressure guided wave radar level gauge dedicated to continuous measurement of boiler drum water level for Ruida Thermal Power Plant

1. Product Overview
In the production sites of process industries such as chemical industry, coal chemical industry, oil and gas, electric power and metallurgy, core equipment like reactors, high-pressure storage tanks and process vessels are exposed to extreme and complex working conditions for a long time, including high temperature, high pressure, strong corrosion, steam condensation, medium coking and scouring. Conventional level gauges are prone to problems such as measurement deviation, signal fluctuation and reduced stability, which cannot meet the demand for continuous, accurate and stable level monitoring under harsh working conditions, and this is a core pain point in industrial instrument selection and on-site application.
To solve the measurement challenges under harsh industrial conditions and support the localization upgrade of industrial instruments, Ruidar Industrial Group independently developed and launched the CGR8600 high-temperature and high-pressure guided wave radar level gauge. The product is specially designed for liquid level measurement under extreme working conditions. Relying on mature guided wave radar measurement technology, with diversified probe structures, special material configurations and explosion-proof protection designs, it can effectively adapt to various complex process scenarios, realize high-precision and high-stability level monitoring under high-temperature, high-pressure, strong corrosion and multi-interference environments, and is widely suitable for new projects and retrofitting of existing devices, providing a reliable domestic measurement solution for the safe production and efficient operation of process industries.
2. Core Features of the Product
2.1 Multi-structure and multi-material adaptation, covering all complex medium working conditions
The CGR8600 high-temperature and high-pressure guided wave radar level gauge supports various probe structures, including three mainstream types: cable + weight type, rod type and coaxial type, which can adapt to different container structures, medium states and process conditions. At the same time, high-quality materials such as 316L stainless steel, PTFE and graphite ceramics can be flexibly selected according to the on-site working conditions to solve various working condition problems in a targeted manner.
Among them, the graphite ceramic special probe has excellent corrosion resistance, anti-scouring performance and anti-fouling and anti-coking performance, and is perfectly suitable for harsh working conditions with strong corrosion, easy coking of medium and high-speed scouring; the coaxial probe can accurately eliminate interference factors such as steam, condensation and air flow disturbance in the tank, greatly improving the measurement stability in complex gas phase environments. The product has completely broken the adaptation limitations of traditional standard instruments, realizing a precise measurement solution of "customized according to needs and adapted to working conditions".
2.2 High-precision and stable measurement, adapting to extreme process fluctuation scenarios
The product is equipped with a high-performance guided wave radar measurement core, with excellent measurement performance and leading core measurement parameters in the industry: the maximum measurement range can reach 6 meters, the measurement accuracy is ±2mm, the resolution is 1mm, and the response time is less than 2 seconds. It can capture subtle dynamic changes of liquid level in the process in milliseconds and feed back the production working conditions in real time.
Compared with traditional radar level gauges, the guided wave measurement mode guides the radar signal directionally through the probe, which can effectively avoid problems such as steam, foam, medium turbulence and gas phase interference inside the tank, eliminate signal drift and measurement jump, and provide continuous, stable and accurate level monitoring data for complex container environments, ensuring that process parameters are controllable and adjustable.
2.3 Flexible debugging and docking, compatible with the factory's mainstream control systems
The product has extremely strong system compatibility and debugging convenience. It is equipped with industrial general communication protocols such as 4-20mA analog quantity, HART and RS485, which can seamlessly connect with the factory's existing DCS, PLC and other control systems without transforming the original system architecture, and has strong adaptability.
The human-computer interaction and debugging methods are diverse and convenient. The equipment is equipped with an LCD on-site display screen, which supports local real-time data viewing; it also supports multiple operation modes such as independent display next to the tank, Bluetooth wireless debugging and remote configuration of upper computer software. On-site personnel can quickly complete parameter debugging, data calibration and fault troubleshooting without frequently opening the cover, greatly reducing the on-site operation and maintenance workload.
2.4 Multi-mode installation adaptation, taking into account both new construction and transformation projects
To adapt to different on-site installation conditions, the product has an optimized structural design, supports multiple installation methods such as flanges and threads, and can be adapted to various process equipment such as vertical, horizontal and special-shaped tanks; the electrical interface is equipped with two specifications of M20×1.5 and 1/2NPT as standard, meeting the wiring requirements of most industrial sites.
The product takes into account both the standardized installation of new projects and the instrument upgrading and transformation scenarios of old devices and existing equipment. There is no need to drill holes to modify the tank or make major changes to the pipeline. It has strong installation adaptability and high transformation efficiency, effectively reducing the project construction cost and construction period.
2.5 High protection and explosion-proof design, adapting to high-risk industrial sites
The protection rating of the whole product reaches IP67, which can effectively resist dust accumulation, rainwater spraying and erosion of outdoor humid environments, and adapt to harsh on-site climates and equipment operating environments. At the same time, it is equipped with multiple explosion-proof structural designs and has passed professional explosion-proof certification, and can be safely applied to various explosive hazardous environments such as Zone 0, Zone 1 and Zone 2, fully meeting the safety use standards of high-risk production areas such as petrochemical industry, coal chemical industry and fine chemical industry, and ensuring the safety of production and operation from the hardware level.
