Principle of Infrared Liquid Pull Controller

The oil intake is automatically controlled by the inlet valve, bypass valve, solenoid valve, infrared level sensor, and oil pump;

1）When the oil level is higher than the upper infrared control oil level, the inlet solenoid valve automatically closes and the oil pump automatically starts; When the oil level is below the upper infrared control level, the oil inlet solenoid valve automatically opens;

2）When the oil level is below the lower infrared control level during equipment operation, the oil pump automatically stops and the stop indicator light is on; When the oil level rises above the lower infrared control level, the oil pump automatically starts and the running indicator light is on;

Oil filter accessories: LZH-2 infrared level controller, now model changed to TRH-3 infrared level controller
