How It Works:

A hydrostatic level sensor uses a fundamental principle of physics: pressure increases with depth in a liquid. The sensor itself is essentially a pressure gauge that can be submerged in the liquid or mounted on the outside of a container.

Here's how it works:

1. Pressure Measurement: The sensor has a pressure diaphragm that detects the force exerted by the liquid pressing against it.
2. Hydrostatic Pressure: This pressure is directly proportional to the weight of the liquid above the sensor, which is known as hydrostatic pressure.
3. Liquid Level Calculation: Since pressure increases with depth, the sensor can essentially translate the measured pressure into the liquid level based on its position in the container.

Key points to remember:

• Sensor Placement: For accurate measurement, the sensor is typically placed at the bottom of the container.
• Atmospheric Pressure: Hydrostatic sensors often have a vent open to the atmosphere to account for atmospheric pressure changes.
• Liquid Density: While the pressure is proportional to depth, it's also important to consider the liquid's density for precise level calculation.

Overall, hydrostatic level sensors are a simple yet effective way to measure liquid level in various tanks and containers. They are robust, reliable, and can be used with a wide range of liquids.
