BAMO KFS flap string-loaded type flowmeter is used to evaluate flows in piping from DN25 up to DN600. Each flow indicator is calibrated according to customer requirements and equipped with a scale specific to the medium.

The measuring cell includes a flap spring-loaded moved by the medium. The angle of rotation of the flap changes according to the flow. A magnetic coupling transfers the movement to a pointer on a dial.

Options: Contact outputs: For process control purposes, the measuring device can be equipped with contacts, inductive or Reed type. Each contact (max. 2) is adjustable over the entire measurement range.
