Coolant Storage Tank Level Sensor Maintenance
Maintaining the level sensor of a coolant storage tank is crucial for accurate monitoring and preventing system failures. Regular maintenance ensures reliable operation and prevents issues like overfills, dry runs, or inefficient coolant usage.
Maintenance Procedures
- Weekly Perform visual inspections: check for corrosion, especially on metal components, as coolant additives or contaminants can accelerate rust.
- Weekly Wipe the sensor's probe or float with a soft cloth dampened with distilled water to remove residue—buildup of sludge, algae, or mineral deposits can block sensors, causing incorrect readings.
- Monthly Verify calibration using the system's manual. Most sensors have adjustment screws or digital settings to align with actual fluid levels; use a dipstick to compare readings and recalibrate if off by more than 5%.
- Monthly For ultrasonic or optical sensors, ensure the detection path is unobstructed by wires, debris, or tank walls—misalignment often leads to false low/high level alerts.
- Quarterly Inspect wiring connections for looseness or oxidation. Tighten terminals gently and apply dielectric grease to protect against moisture.
- Quarterly For float-based sensors, check the float's movement: it should glide smoothly without sticking. Lubricate pivot points with a silicone-based lubricant.
- Annually Replace worn gaskets or O-rings to prevent leaks around sensor ports.
Important: Always power off the system before performing maintenance to avoid electrical shocks. Avoid petroleum-based lubricants that can degrade rubber components.
Following these maintenance steps ensures the sensor remains reliable, preventing operational failures and maintaining efficient coolant system performance.
