Product Overview
Based on ATST Electric’s core concept of “Precise Control, Safe and Reliable”, SSRC-04 Liquid Level Controller is developed for automatic liquid level control in water supply, drainage and storage systems. The product monitors the liquid level through connected probes or electrodes and controls the pump circuit according to the actual water level condition.
When the water level reaches the preset upper or lower control point, SSRC-04 can output a control signal to start or stop the pump, helping prevent overflow, dry running and unnecessary manual operation. It is especially suitable for systems that require stable liquid level management and automatic pump protection.
With compact structure, convenient wiring and reliable control performance, SSRC-04 can be installed in distribution boxes, pump control panels and automation cabinets. It provides a practical solution for water tanks, wells, reservoirs, cooling systems and industrial liquid management systems.
Main Features
1. Automatic liquid level control: Detects high and low liquid levels and controls pump operation automatically according to system requirements.
2. Pump start-stop management: Helps start the pump when water replenishment or drainage is required and stop the pump when the target level is reached.
3. Dry-run protection support: Prevents pumps from operating under insufficient water conditions, helping reduce motor damage and maintenance cost.
4. Overflow prevention: Stops water filling or pumping operation when the liquid level reaches the upper limit, improving system safety.
5. Reliable probe control: Works with liquid level probes or electrodes to detect water level changes in tanks, wells and reservoirs.
6. Compact installation design: Space-saving structure is suitable for control cabinets, pump panels and distribution boxes.
7. Simple wiring and commissioning: Clear control logic makes installation, testing and maintenance convenient for electrical technicians.
8. Wide application compatibility: Suitable for water supply, drainage, irrigation, cooling and industrial liquid control systems.
Application Scenarios
1. Water tank level control: Used for automatic filling and stopping control in building water tanks, roof tanks and storage tanks.
2. Pump control systems: Suitable for water supply pumps, drainage pumps, circulation pumps and booster pump control applications.
3. Well and reservoir management: Applied in wells, reservoirs and water collection systems to control pump operation according to water level.
4. Industrial liquid systems: Used in cooling water systems, process water tanks and auxiliary liquid control equipment.
5. Agricultural irrigation systems: Suitable for irrigation tanks, water storage systems and automatic pump control in farms and greenhouses.
6. Building water supply systems: Applied in residential buildings, hotels, schools and commercial facilities for automatic water level management.
7. Drainage and sewage systems: Helps control drainage pumps in basements, sumps, wastewater tanks and collection pits.
