The FLS series operates on the principle of the magnetic reed switch. A magnet is mounted to a flapper inside the housing. Its normal resting position is with the flapper in a position subject to liquid flow. As pressure increases with flow rate, the flapper is forced away from its magnetically maintained at rest position. Using a magnet to maintain the resting position is unique. Switches of similar design typically apply a spring to maintain the flapper in its resting position. The spring is a mechanical component that is prone to failure. Material in the liquid may corrode or jam the spring. It may break after some point due to the corrosion. Particles from corrosion may break loose and contaminate the product. The magnet in FLS is selected at the factory for a particular flow rate. The magnets are high quality and the flow rate switch point is very repeatable over time. Springs will loose resistance over time and the setpoint will drift. The FLS is available in many configurations for OEM flexibility. The housing is available in Noryl plastic, brass or stainless steel. Other materials are optionally available upon request. |

Formerly known as STI Automation and Lundahl Inc. In September 2006 Scientific Technologies, Inc. (STI) sold its Automation Products Group to Automation Products Group, Inc. (APG), a new company formed as a result of STI Safety Products Group’s recent merger with a subsidiary of Japan-based Omron Corporation. “This change will be completely transparent for Automation Products Group, Inc. customers, and they can expect the same level of high quality automation products and services that they have come to depend on over the years,” says Jim Vella, APG President. “Automation Products Group, Inc. will continue to be a single source for process and automation sensor solutions.”Reviews
