BECSys Rotary Flow Switch with Directional Detection – 2100419

The BECSys Rotary Flow Switch (Part #2100419) is a high-performance paddle-type flow switch designed to monitor sample stream flow in BECSys water chemistry systems. Unlike traditional flow switches, this model features directional detection, allowing it to verify not only that flow is present—but that it’s moving in the correct direction.

This critical distinction provides an extra layer of protection for your sensors and chemical feed equipment by helping prevent backflow scenarios and ensuring consistent water quality monitoring and chemical feed safety. Built with chemical-resistant materials and designed for compatibility with BECSys molded flow cells and other sampling systems, this flow switch is ideal for both new installations and field upgrades.

Key Features

✔ Directional Flow Detection – Confirms that sample water is flowing the correct way
✔ Rotary Paddle Design – Reliable and durable under varied flow conditions
✔ Enhances Safety – Prevents backflow-related issues and chemical misfeeds
✔ BECSys Compatible – Integrates directly with BECSys controllers and molded flow cell assemblies
