The Automatic ATO Liquid Level Controller from Shenzhen Ept Tech Co., Ltd is a two-stage optical sensor system designed for automatic water level management. It uses a high-grade PC probe to detect liquid presence without corrosion, triggering a pump when water is absent (after a 3-second delay) and stopping it when water is detected. The controller includes high and low alarm indicators and is suited for both clean and non-corrosive liquid applications.
The sensor employs optical type level sensing, which relies on light refraction to distinguish between air and liquid. Standard controllers in this category support 220-240V AC power for the pump and a 12-24V DC supply for the control circuit. The PC probe is typically rated for IP65 or higher to resist moisture ingress, while the control box is made from ABS or similar flame-retardant plastic.
Common applications include sump pits, water storage tanks, and industrial drainage systems in hotels, factories, and commercial complexes. The controller is designed for continuous operation, with typical duty cycles allowing the pump to run for extended periods without overheating. Buyers should confirm the maximum current rating for the pump relay and the environmental temperature range for the control electronics.

Before ordering, confirm the controller’s compatibility with your pump’s voltage and current requirements. Request the relay’s current rating and the control circuit’s voltage range to avoid mismatches. For applications involving corrosive liquids or extreme temperatures, specify these conditions to the supplier and ask for a probe material that meets your needs.
Logistics for this controller are straightforward due to its compact size, but verify packaging to prevent damage during transit. The supplier’s address in Shenzhen suggests proximity to major ports, so lead times for sea freight should be reasonable. Clarify Incoterms, as EXW or FOB terms will determine your responsibility for shipping and insurance. Payment terms for electronic controls often include a deposit, with the balance due before shipment.
Quality checks should include testing the controller with your actual liquid and pump. Validate the 3-second delay and alarm functionality under real-world conditions. Request a certificate of conformity for the probe material and enclosure, and ensure the supplier provides a warranty for defects. Post-installation, monitor the system for false triggers, which can indicate issues with the optical sensor’s alignment or calibration.
