Dwyer Series BFM Piezo Bulk Flow Monitor

Piezo flow switches are sensors with an electrical contact output. The bulk flow monitor provides effective monitoring for most flow/no flow conditions in pipes. Applications include oil spray systems, rotary drums, distributors, and food processing. Dwyer's piezo flow switch offers many features that exceed the industry standards. Series BFM Bulk Flow Monitor provides effective monitoring for most flow/no flow conditions in pipes and chutes. It's sensing techniques, which use a Piezo element, makes the BFM versatile for most flow/no flow applications.

Dwyer Series BFM Piezo Bulk Flow Monitor | Descriptions

The Series BFM Piezo Bulk Flow Monitor offers many unique advance features that exceed the industry standards. The BFM Central Processing Unit monitors movement of almost anything through a pipe or chute system. The BFM is ideal for sensing the presence or absence of materials in Pneumatic Conveying Systems. The BFM offers adjustable sensitivity depending on the application demand. Also, it provides easy installation and requires no maintenance. The unit has LED indicators -- flow (green)/no flow (red). The BFS-1 Sensor yields many advance features. It externally mounts to the outside of the pipe or chute. It provides mounting tabs for easy installation. The Sensor is prewired with 3' wire.
