Flow Sensors

Reliable and accurate mass airflow (MAF) sensors are required for a variety of automotive, medical, and industrial gas flow applications.

These flow switches are suitable for hot and cold potable water due to rugged brass housings and the ability to operate from a small head of water. They are typically mounted in a well-defined channel, directly in the flowing media.

The flow switches are designed for water control, power shower, central heating systems, circulation pump protection, cooling, and leak detection. They feature reed switch reliability and are easy to install.
