FTI51 Product Overview
FTI51 is a flow instrument used for industrial process measurement, widely applied in industries such as water treatment, chemicals, petroleum, and electric power. Its design balances high precision and long-term stability, making it suitable for occasions requiring continuous flow monitoring and control.
The instrument usually outputs standard analog signals or digital communication signals, making it easy to connect to control systems such as PLC and DCS. Understanding its core parameters and installation requirements is the prerequisite for ensuring measurement accuracy.

| Accuracy Class | ±0.5% FS or higher |
| Output Signal | 4-20mA / pulse / RS485 |
| Power Supply | 24VDC or 220VAC |
| Protection Rating | IP65 / IP67 |
| Ambient Temperature | -20℃ ~ +60℃ |
Installation Steps and Precautions
Correct installation is the key to ensuring the measurement accuracy of the FTI51. Please follow the steps below and strictly observe the precautions.
- Confirm the installation location: Choose a pipe section with low vibration and easy observation and maintenance, and ensure that the lengths of the upstream and downstream straight pipe sections meet the requirements of the manual.
- Check the pipeline and instrument: Confirm that the pipeline has no impurities, the instrument is not damaged, and the seals are intact.
- Install the instrument: Install in the direction indicated by the flow arrow, and tighten the connecting bolts evenly to avoid deformation caused by excessive force.
- Electrical connection: Connect the power and signal lines according to the wiring diagram in the manual, and note that the shielding layer should be grounded at one end.
- Power-on commissioning: After power-on, check whether the display and output are normal, and perform zero calibration if necessary.
- It is strictly prohibited to disassemble the instrument under pressure.
- Avoid installation near strong electromagnetic interference sources.
- For gas measurement, ensure that the pipeline is dry and free of condensed water.
Operation and Maintenance Points
Daily operation should follow the menu structure in the Chinese manual for parameter settings to avoid mistakenly changing key coefficients. Regular maintenance can extend the service life of the instrument and maintain measurement accuracy.
- Regular inspection: Check quarterly whether the wiring terminals are loose and whether water has entered the housing.
- Cleaning and upkeep: According to the characteristics of the medium, regularly clean the sensor surface to prevent scaling or blockage.
- Calibration cycle: It is recommended to calibrate once a year, and for high-precision applications it can be shortened to half a year.
- Troubleshooting: If there is no display or abnormal output, first check the power supply and signal loop, then troubleshoot according to the fault code table in the manual.
FAQ
Where can I download the FTI51 Chinese manual?
You can download the PDF file directly at the top of this page, or contact the supplier to obtain a paper copy. It is recommended to save the electronic version for reference at any time.
Does the FTI51 support HART communication?
Some models support the HART protocol. Please check the instrument nameplate or consult the manufacturer for details. The standard configuration is usually 4-20mA plus RS485.
What are the straight pipe section requirements during installation?
Generally, the upstream straight pipe section is required to be no less than 10 times the pipe diameter, and the downstream no less than 5 times the pipe diameter. If space is limited, a flow conditioner can be used, but this must be confirmed in the manual.
