FTI52 Product Overview
FTI52 is an industrial instrument used for continuous level measurement, commonly found in working conditions involving liquids, slurries, and granular solids. It is based on radar or guided wave radar principles and features high precision and strong anti-interference capability. Based on the manual content, this article extracts key technical and application information for reference by engineering technicians and procurement personnel.
Working Principle
FTI52 emits high-frequency electromagnetic waves and receives echoes to calculate the distance to the material surface. The built-in algorithm can suppress false echoes, ensuring stable output under complex conditions such as stirring and foam.
- Non-contact measurement, suitable for corrosive media
- Supports 4-20mA/HART and other signal outputs
- Can be equipped with a display module for intuitive on-site readings
Typical Applications
- Chemical storage tank level monitoring
- Sludge level in water treatment sedimentation tanks
- Hygienic applications in food and pharmaceutical industries
- Powder inventory in cement silos
Technical Parameters and Selection
Selection requires focusing on process connection, measuring range, accuracy, and medium characteristics. The table below lists common specifications of FTI52; the manual shall prevail for specific details.
| Parameter | Typical Value | Remarks |
|---|---|---|
| Measuring Principle | Radar/Guided Wave Radar | Depends on model |
| Measuring Range | 0~20m | Customizable |
| Accuracy | ±3mm | Standard conditions |
| Process Connection | Flange/Thread | DN50/DN80, etc. |
| Output Signal | 4-20mA/HART | Optional RS485 |
| Protection Rating | IP67 | Optional IP68 |
| Process Temperature | -40~150℃ | High-temperature version up to 200℃ |
| Process Pressure | -0.1~4MPa | Depends on connection type |
Selection Steps
- Confirm medium characteristics: dielectric constant, corrosiveness, and whether it is prone to adhesion.
- Determine the measuring range and accuracy requirements, and select the corresponding model.
- Select the process connection and material according to the tank interface.
- Confirm the power supply and output signal to match the control system.
- Check environmental conditions: temperature, pressure, and explosion-proof rating.
Installation and Commissioning Points
Correct installation can significantly improve measurement stability. The following points are excerpted from the FTI52 Chinese manual; strictly follow them during on-site operations.
Installation Precautions
- Avoid the feed inlet and agitator to prevent false echoes.
- Keep the antenna perpendicular to the material surface to reduce energy loss.
- Clean the flange sealing surface to ensure no leakage.
- For outdoor installation, it is recommended to add a sunshade to avoid direct high-temperature exposure.
Commissioning Steps
- After power-on, check whether the display and output are normal.
- Enter empty tank and full tank parameters to perform zero and span calibration.
- Enable the echo suppression function and record the interference curve.
- Verify the analog output to ensure consistency with the host computer.
- Save parameters and record the commissioning report.
Maintenance and Troubleshooting
Regular maintenance can extend the service life of FTI52. Common faults are mostly related to antenna contamination, power supply, or parameter settings.
- Check the antenna quarterly for scaling and clean it if necessary.
- Output fluctuation: check grounding and shielding wires.
- No echo: confirm whether the medium dielectric constant is too low.
- Abnormal display: check the supply voltage and fuse.
