Dwyer BFM series Piezo Bulk Flow Monitor

Wiratama Mitra Abadi 01 01.57 flow measurement,

Dwyer BFM series 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.
