SM4001 Overfill Protection Device, Float Switch, Liquid level sensor

An Overfill Protection Device (OPD) is a safety mechanism designed to prevent liquid containers from overfilling and causing potential hazards. One of the key components of an OPD is a Float Switch that uses a Liquid Level Sensor to detect the level of liquid in the container. The Float Switch is a simple yet effective device that consists of a buoyant object attached to a lever arm, which moves as the liquid level rises or falls.

As the liquid level approaches a predetermined threshold, the Float Switch triggers the OPD, which shuts off the flow of liquid into the container. This prevents the container from overfilling and potentially causing damage or harm. Liquid Level Sensors are commonly used in a variety of industries, such as oil and gas, water treatment, and chemical processing.
