Specifications - Installation and Operating Instructions

Series BFM Bulk Flow Monitor

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.

The BFM Control 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

L.E.D 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.

Series BFM has many practical applications. You can use it

to monitor Oil Spray Systems, Discharge Chutes,

Distributors, Screw Conveyors, Drag Conveyors, Water

Systems, Air Systems, Pneumatic Systems, Gravity Feed

Systems, Slurry Systems, Chemical Processing, Food

Processing and Rotary Drums.
