Side Entry Level Switches – Reliable Monitoring for Liquids

At Amironic, we offer a proven range of side entry level switches designed to ensure accurate and dependable liquid level detection across multiple industries. These compact and robust sensors are built for long service life, simple installation, and seamless integration into tanks, pipes, and process systems.

What is a Side Entry Level Switch?

A level switch is a sensor that detects the presence or absence of liquid at a defined level. Unlike top-mounted models, side entry level switches are installed horizontally through the wall of a tank or vessel. This makes them ideal where vertical space is limited or where easy access for maintenance is required.

The switch operates by detecting the rising or falling liquid level and providing an electrical signal for control, monitoring, or safety shut-off. This helps prevent overfilling, dry running of pumps, and ensures optimal fluid management.
