water level indicator

A water level indicator is a device or system used to monitor and display the level of water in a container, tank, or reservoir. It typically consists of the following components:

Sensors: These are placed at different levels within the container to detect the water level. Common types of sensors include float switches, ultrasonic sensors, and pressure sensors.

Control Unit: The control unit processes the signals from the sensors and determines the water level. It may also contain circuitry for power management and signal conditioning.

Display: The water level is usually displayed on an indicator panel, which can be in the form of LED lights, a digital display, or even a simple analog gauge.

Alarm System (optional): Some water level indicators include an alarm system that triggers when the water level reaches a certain threshold. This is especially useful for preventing overflows or low water levels in critical applications.

Power Source: Water level indicators are typically powered by batteries or through a direct electrical connection.
