Product Overview
Based on ATST Electric’s core concept of “Precise Control, Safe and Reliable”, SSR04 Liquid Level Controller provides a practical solution for automatic water level control in industrial, commercial and building water systems.
The controller works with liquid level probes or electrodes to detect the upper and lower water levels in a tank, well or reservoir. According to the detected liquid level, SSR04 can control the pump circuit automatically, helping achieve water filling, drainage, dry-run prevention and overflow protection.
By replacing manual pump operation with automatic level control, SSR04 helps reduce labor work, avoid pump damage caused by abnormal water level conditions, and improve the reliability of water supply and drainage systems. Its compact structure makes it suitable for installation in pump control boxes, electrical panels and automation cabinets.
Main Features
1. Automatic liquid level monitoring: Detects liquid level changes through probes or electrodes and provides reliable control signals.
2. Pump start-stop control: Automatically starts or stops the pump according to the preset upper and lower water levels.
3. Dry-run protection support: Helps prevent pump operation when the water source level is too low, reducing motor damage risk.
4. Overflow prevention: Stops filling or pumping operation when the upper level is reached to avoid water overflow.
5. Electrode-based detection: Suitable for conductive liquid level control in tanks, wells, reservoirs and water systems.
6. Compact controller design: Easy to install inside pump control panels, distribution boxes and electrical cabinets.
7. Simple wiring and maintenance: Clear control logic supports convenient installation, commissioning and daily maintenance.
8. Wide application range: Suitable for water supply, drainage, irrigation, cooling and industrial liquid management systems.
Application Scenarios
1. Water tank control: Used for automatic filling and stopping control in roof tanks, storage tanks and building water tanks.
2. Pump control systems: Suitable for water supply pumps, drainage pumps, booster pumps and circulation pumps.
3. Well and reservoir systems: Applied in wells, reservoirs and water collection systems to control pump operation according to water level.
4. Building water supply: Used in residential buildings, hotels, schools and commercial facilities for automatic water level management.
5. Agricultural irrigation: Suitable for irrigation tanks, farm water systems and greenhouse water supply control.
6. Industrial liquid control: Applied in cooling water tanks, process water systems and auxiliary liquid storage equipment.
7. Drainage and sewage systems: Used in basements, sump pits, wastewater tanks and drainage pump control applications.
