II. Common Issues and Solutions

No output or abnormal output

• Causes: Abnormal power voltage, incorrect wiring, sensor failure or damage to internal components of the transmitter.
• Solutions: Check whether the power voltage meets requirements, verify correct wiring, inspect sensor status, and replace internal transmitter components if necessary.

Large fluctuations in measured values

• Causes: Unstable fluid in the pipeline, improper sensor installation position or unreasonable transmitter parameter settings.
• Solutions: Optimize pipeline design to ensure stable fluid flow; adjust sensor installation position to avoid interference from bubbles or eddies; recalibrate transmitter parameters.

Communication interruption

• Causes: Loose communication cables, incorrect communication protocol configuration or faulty communication module.
• Solutions: Check communication cable connections, confirm correct communication protocol settings, and replace the communication module if necessary.

IV. Usage Precautions

• Electrostatic protection: Wear an anti-static wrist strap during installation and maintenance to avoid electrostatic damage to internal transmitter components.
• Installation environment: Install the transmitter in a dry, ventilated area free of corrosive gases, away from direct sunlight and rain.
• Wiring standards: Follow the wiring diagram strictly to ensure correct connection of power, signal and communication cables.
• Parameter setting: Recalibrate parameters according to actual working conditions during initial use or transmitter replacement to guarantee measurement accuracy.
• Regular inspection: Periodically check the transmitter’s operating status, including power voltage, output signals and communication connections, to ensure normal operation.

V. Maintenance Recommendations

• Cleaning and inspection: Regularly clean dust and debris from the transmitter surface using dry compressed air, and check for loose or oxidized wiring terminals.
• Calibration and adjustment: Calibrate and adjust the transmitter at least once a year to maintain measurement accuracy.
• Spare parts management: Keep commonly used spare parts (such as sensors and communication modules) in stock for quick replacement of faulty components.
• Professional training: Provide professional training for operators to familiarize them with operation and maintenance procedures, improving equipment efficiency and service life.
