1. Core Positioning​ A key monitoring component for automotive coolant tanks and industrial cooling water tanks. Installed inside or on the sidewall of the tank, it real-time monitors the level of coolant/cooling water and transmits signals to the instrument or controller (ECU/industrial controller). It triggers an alarm (indicator light/buzzer) when the level is low, preventing engine overheating and equipment damage caused by tank dry burning. Compatible with fuel vehicles, new energy vehicles and industrial cooling systems.​ 2. Core Functions​ Accurate Level Monitoring: Measurement range 0-100% (from full to low tank level), accuracy ±2%FS. Uses float/capacitive sensing to stably capture level changes;​ Low-Level Alarm: Immediately sends an alarm signal when the level is below the safety threshold (e.g., 10%) to avoid delayed water replenishment;​ Environmental Resistance: Coolant-resistant housing (PP/PA material), IP6K9K protection, temperature resistance -40℃ to 120℃, vibration resistance (10-2000Hz);​ Fault Diagnosis: Generates fault codes (e.g., P0201) when the sensor malfunctions, facilitating quick troubleshooting.​ 3. Core Advantages​ Dedicated Adaptation: Fits different tank structures (round/square) and adapts to multiple level ranges;​ Easy Installation: Snap-on/threaded interface, direct OE replacement without tank modification;​ Compliant & Reliable: Certified to IATF16949 and ISO 14001, meets RoHS standards, service life ≥4 years/120,000km.​ 4. Adaptability​ Vehicles: Fuel/B EV/PHEV passenger vehicles (sedans/SUVs), commercial vehicles (heavy-duty trucks/buses);​ Scenarios: Automotive engine coolant tanks, industrial equipment cooling tanks (e.g., generator/machine tool tanks).​ 5.
