Adopts advanced guided wave radar technology, which transmits high-frequency pulse signals along the measuring probe. When encountering interfaces with different dielectric constants, part of the signal is reflected back. The liquid level height is calculated based on the time difference between the transmitted and reflected signals. This principle ensures precise measurement and is not affected by changes in medium properties such as density and temperature.
The measuring range typically reaches 6 meters, which can meet the needs of liquid level measurement in most common industrial containers and is also effective in scenarios with large tanks or high liquid level drops.
The accuracy can reach ±1mm. High precision ensures the accuracy of liquid level monitoring in the production process, reducing production accidents or product quality issues caused by liquid level errors.
Supports multiple output signals, such as 4-20mA analog signals, which are easy to integrate with traditional control systems. It also features the HART communication protocol, enabling remote diagnosis, parameter setting, and data transmission to meet the needs of modern industrial automation control.
It can continuously monitor liquid level changes in real-time, providing dynamic liquid level data for the production process, which is helpful for production scheduling and control.
It can not only measure a single liquid level but also be used to measure the interface between two different media, such as the interface between oil and water, which has important applications in the petrochemical industry and other fields.
It can monitor its own working status in real-time. When a fault or abnormality occurs, it can promptly send an alarm signal and transmit detailed fault information to the control system through the HART communication protocol, facilitating maintenance personnel to quickly locate and solve problems.
It can adapt to a temperature environment of -40℃ to 150℃ and work stably within a wide temperature range, whether in outdoor storage tanks in cold regions or container liquid level measurement in high-temperature processes.
It can withstand pressures up to 40bar, making it suitable for liquid level measurement in high-pressure environments, such as high-pressure reactors in the petrochemical industry.
Due to its guided wave radar measurement principle, it has strong adaptability to media. It can measure various liquids, including corrosive liquids such as sulfuric acid and hydrochloric acid, as well as high-viscosity liquids such as lubricating oil and syrup. It can also accurately measure the liquid level of liquids with impurities and foam.
Flow correlation is not a direct flow measurement device, but high-precision liquid level measurement can indirectly provide accurate data for flow calculation. Combined with information such as container shape and size, the flow rate is calculated through the rate of liquid level change. Due to the high accuracy of liquid level measurement, the indirect flow calculation accuracy is also relatively high.
High viscosity applicability: With guided wave radar technology, for high-viscosity media such as asphalt and heavy oil, radar waves can penetrate and reflect accurately without being affected by high viscosity, enabling precise liquid level measurement.
Long lift adaptation: Since the measuring range can reach 6 meters, it can meet the needs of some situations where a larger lift is required to reach the measuring point. For example, it has advantages in liquid level measurement scenarios such as tall silos and deep wells.
High-precision measurement, multiple measurement functions (continuous liquid level and interface measurement), as well as powerful self-diagnostic functions and communication capabilities, make it have significant advantages in complex industrial environments and production processes with high-precision requirements. It is suitable for industries with strict liquid level measurement requirements such as large enterprises.
Wide temperature, pressure, and media adaptability: It can work in a wide range of temperatures, pressures, and various complex media conditions without frequent equipment replacement, reducing maintenance costs and equipment procurement costs.
Recommended for large petrochemical projects, large oil storage tanks in the power industry, large water treatment plants, etc. These occasions have high requirements for measurement accuracy, functional diversity, and environmental adaptability. The FTL51 series can meet their needs and ensure safe and efficient production operations.
Remote monitoring needs: For enterprises with remote monitoring systems, the HART communication protocol of the FTL51 series can facilitate remote diagnosis and parameter setting, reducing on-site maintenance workload and improving management efficiency.
Petrochemical industry: In crude oil storage tanks in refineries, reaction kettles in chemical production, intermediate tank areas, etc., high-precision measurement of liquid level and interface is required, and it is necessary to adapt to harsh environments such as high temperature, high pressure, and strong corrosion. The FTL51 series can meet the needs.
Power industry: Used for liquid level measurement of acid-base storage tanks and demineralized water tanks in power plants. It requires equipment to have high precision, reliability, and a wide temperature adaptation range. The FTL51 series can ensure accurate monitoring of the liquid level of related media in the power production process.
Food and beverage industry: In liquid level measurement of syrup tanks and fermentation tanks in large beverage factories, it is necessary to ensure measurement accuracy and meet hygiene requirements. The FTL51 series can meet food-grade hygiene standards by selecting appropriate probe materials.
Top mounting: The most common installation method is to vertically install the level transmitter on the top of the container, with the probe extending into the container. This installation method is suitable for most containers, easy to install and maintain, and can achieve good measurement results. During installation, ensure that the probe is vertical and avoid contact with internal components of the container, which may affect measurement accuracy.
Side mounting: For some containers with limited top space or inconvenient top installation, the side mounting method can be adopted. At this time, attention should be paid to selecting an appropriate installation position to avoid interference from liquid flow, stirring, etc., on the measurement. At the same time, ensure that the probe is parallel to the container wall to ensure accurate measurement.
Although the FTL51 series has a wide range of temperature and pressure adaptation, in harsh environments or with frequent pressure changes, it is necessary to regularly check the equipment performance to prevent equipment aging or performance degradation due to environmental factors. Avoid installation in strong electromagnetic interference environments. If unavoidable, take effective shielding measures to prevent radar signals from being interfered with and affecting measurement accuracy.
For media that are prone to crystallization and scaling, long-term use may cause adhesion on the probe, affecting measurement accuracy. The probe needs to be cleaned and maintained regularly, and appropriate cleaning methods and cleaning agents should be selected to avoid damaging the probe.
Install strictly in accordance with the installation instructions to ensure the correct installation position and no bending or deformation of the probe. Calibration should be performed after installation to ensure accurate and reliable measurement data.
Based on the capacitive measurement principle, it uses the capacitance formed between the probe and the container wall. When the liquid level changes, the capacitance value changes accordingly, and the liquid level height is determined by detecting the capacitance change. This principle is suitable for measuring media with relatively stable dielectric constant changes.
The general measuring range is about 2 meters, which is narrower than that of the FTL51 series, making it more suitable for small containers or occasions with small liquid level changes.
The accuracy is about ±2mm. Although it is slightly lower than that of the FTL51 series, it can also meet some application scenarios with low precision requirements.
It mainly outputs 4-20mA analog signals, meeting basic industrial signal transmission needs, but its communication function is relatively single compared to the FTL51 series and does not have the HART communication protocol.
Focus on simple liquid level measurement tasks, providing users with basic data on liquid level height.
Upper and lower limit alarm values can be set. When the liquid level reaches or exceeds the set value, an alarm signal is sent to the control system through changes in the 4-20mA signal to remind operators to pay attention and ensure production safety. However, it does not have the function of self-diagnosing detailed fault information, making fault 排查 relatively difficult.
The applicable temperature range is -20℃ to 80℃, which is narrower than that of the FTL51 series, suitable for normal temperature or environments with little temperature change.
The maximum pressure it can withstand is 16bar, suitable for liquid level measurement in medium and low-pressure environments, such as ordinary water tanks and acid-base tanks.
Based on the capacitive principle, it has strict requirements on the dielectric constant of the medium. It is generally suitable for media with relatively stable dielectric constants and no conductive impurities, such as pure water and some organic solutions. For highly corrosive or high-viscosity media, measurement may be inaccurate or the probe may be damaged.
Flow calculation limitations: It also cannot directly measure flow, and due to the relatively low accuracy of liquid level measurement, the error is relatively larger than that of the FTL51 series when used for indirect flow calculation.
Low viscosity applicability: The capacitive principle determines that it has difficulty in measuring high-viscosity media. High viscosity may cause insensitive capacitance changes, affecting measurement accuracy, so it is more suitable for measuring low-viscosity media.
Short lift application: The measuring range is only about 2 meters, suitable for liquid level measurement of short lifts, small equipment, or shallow containers, such as small storage tanks and metering tanks.
Simplicity, practicality, and cost advantages: The structure is relatively simple, which can well realize basic liquid level measurement and liquid level alarm functions. The price is relatively low, making it suitable for small enterprises with low requirements on measurement accuracy and functions, simple production processes, or projects with limited budgets, and has cost advantages.
Suitable for small projects such as liquid level measurement of raw material tanks in small food processing plants and water level monitoring of water pools in small sewage treatment stations. These scenarios are cost-sensitive and have relatively low requirements on measurement accuracy and functions. The FTL31 series can meet their basic needs with high cost performance.
Independent and simple equipment: In some simple equipment that operates independently and does not require complex communication and self-diagnostic functions, such as small liquid storage tanks and small reaction kettles, the FTL31 series can provide reliable liquid level measurement and alarm functions.
Liquid level measurement of ordinary raw material tanks and finished product tanks in small chemical enterprises has low requirements on accuracy and functions. The FTL31 series can meet their basic measurement and alarm needs.
Water treatment: In liquid level measurement of regulating pools and clear water pools in small sewage treatment plants, the FTL31 series can effectively monitor the liquid level with its simplicity, practicality, and cost advantages.
In liquid level measurement of temporary water storage tanks and admixture tanks on construction sites, the FTL31 series can be quickly installed and provide basic liquid level data to meet the simple liquid level monitoring needs in the construction process.
Top insertion installation: Generally, top insertion installation is adopted, where the capacitive probe is vertically inserted into the top of the container. During installation, attention should be paid to the insertion depth of the probe, which needs to be accurately adjusted according to the measuring range and container height. At the same time, prevent damage to the probe and avoid affecting the capacitance measurement accuracy due to collisions.
Side flange installation: For some small containers or occasions requiring quick installation and disassembly, side flange installation can be adopted. The level transmitter is fixed on the side of the container through a flange. During installation, ensure that the flange is well sealed to prevent liquid leakage from affecting measurement and equipment safety.
Due to its sensitivity to the dielectric constant of the medium, it is necessary to accurately understand the dielectric constant of the measured medium and its stability before use. If the dielectric constant of the medium changes, it may lead to increased measurement errors, and it is necessary to recalibrate or replace a suitable level transmitter. It is strictly prohibited to use it for media with conductive impurities to avoid damaging the probe and equipment.
Do not use it beyond the specified temperature and pressure range, otherwise, it may cause equipment damage. When used in an environment with large temperature changes, the impact of temperature on capacitance measurement should be considered, and temperature compensation should be performed if necessary.
Regularly check whether the probe is damaged, corroded, etc., and replace damaged parts in a timely manner. Since it does not have a self-diagnostic function, more attention should be paid to the equipment operation status during daily maintenance, and the normal operation of the equipment should be judged by observing the output signal.
