Water level control system (definition)

Water level control system — is a set of devices and technologies designed to measure, monitoring and water level control in various reservoirs, tanks and systems. Such systems provide safe and efficient water level control, preventing overflow or shortage of liquid, which is critical for the smooth operation of many industrial processes, heating and water supply systems.

Water level control system: main functions and components:

1. Measuring water level: Water level monitoring systems use various sensors and transducers to determine the current water level. These can be ultrasonic sensors, radio wave sensors, float sensors, capacitive sensors and optical sensors.
2. Monitoring: The system continuously monitors water levels in real time. Data can be displayed on displays or transmitted to control systems for further analysis.
3. Management and automation: When critical levels (maximum or minimum) are reached, the system can automatically start or stop pumps, valves or other devices to maintain the required water level. This helps prevent overflow or complete lack of liquid.
4. Alerts and alarms: When preset thresholds are reached, the system can generate alarms or notifications (audible, visual or text) to alert operators to the need for intervention.
5. Data recording and reporting: Modern systems can record water level data, allowing changes to be analyzed over time, trends to be identified, and reports to be prepared for later analysis.

Types of sensors and technologies:

1. Float sensors: Use a float that changes position depending on the water level. The water level control system responds to changes, thanks to the dynamic position of the float, with its help it can activate or deactivate the switches.
2. Ultrasonic sensors: Measures the time it takes for an ultrasonic pulse to travel from the sensor to the water surface and back. This time is converted into water level.
3. Radio wave sensors: They work on the principle of reflecting radio waves from the surface of the water and measuring the reflection time.
4. Capacitive sensors: Measures the change in capacitance between two electrodes located in a reservoir. The change in capacitance is associated with a change in the water level.
5. Optical sensors: Uses infrared rays to determine the water level. The change in the reflection of rays from the surface of the water signals its level.

Application:

1. Industry: Control of water levels in boilers, water tanks, cooling systems and industrial processes.
2. Heating and water supply systems: Monitoring the water level in expansion tanks, boilers and reservoirs.
3. Housing construction: Management of water levels in rainwater, water supply and sewerage systems.
4. Agriculture: Water level control in irrigation, reservoirs and aquaculture.

A water level control system is critical to ensure the safe and efficient operation of various systems that involve the use and management of liquids. Proper use of such systems helps prevent accidents, failures, and saves resources.
