The LZD280 series mining intrinsically safe flow meter acts like a loyal guardian, silently monitoring fluid flow to ensure the production line runs smoothly. However, this "guardian" occasionally encounters minor issues—malfunctions. When the numbers on the display stop changing or readings become abnormal, a tense yet intriguing troubleshooting journey quietly begins. From power lines to sensors, from the display screen to internal circuit boards, every detail is meticulously examined.
LZD280 Series Mining Intrinsically Safe Flow Meter Troubleshooting
I. Common Fault Classification and Troubleshooting Steps
2. Abnormal Flow Display Value (Too High/Too Low/Fluctuating)
Possible Causes:
Medium contains bubbles or impurities (install an exhaust valve or filter).
Pipeline not fully filled or improper installation position (ensure straight pipe sections before and after the flow meter are ≥5 times the pipe diameter).
Incorrect parameter settings (e.g., pipe diameter, range not matching the site conditions, requiring recalibration).
Operational Suggestions:
Check fluid state and installation conditions, perform zero calibration if necessary.

3. Instantaneous Flow is Zero but Actual Flow Exists
Possible Causes:
Flow below startup threshold (adjust instrument sensitivity or check small flow settings).
Probe damaged (e.g., piezoelectric crystal failure, requires factory repair).
Operational Suggestions:
Gently tap the probe with a metal object and observe if the signal changes to preliminarily assess probe condition.
II. Environmental Adaptability Troubleshooting
Temperature Impact: Operating temperature exceeding limits (-20℃ to +60℃) may cause drift; install insulation/thermal protection measures.
Vibration Interference: Reinforce mounting brackets to avoid signal noise caused by mechanical vibrations.
III. Recording and Follow-Up Actions
Fault Log: Record fault phenomena, troubleshooting steps, and results for subsequent analysis.
Support: If the above steps are ineffective, contact the manufacturer for calibration files or replacement parts (disassembly of explosion-proof components is prohibited).
