DS01 Flow Meter/Switch
F.S. Ranges From 60ml to 150 l/min water, 2 to 625 l/min air
DESCRIPTION
The flow meter and switch model DS01 works according to a modified variable area principle. The float is guided in a cylindrical measuring glass by means of a spring. The flowing medium moves the float in the flow direction. The upper edge of the float shows the momentary flow via an etched scale on the measuring glass.
A reed contact is mounted outside the meter in a sealed housing. The float contains a magnet. When the float reaches the position of the reed contact the switch will close. With higher flows the float moves further upward until it reached a built-in float stop, still keeping the switch closed. This ensures a bistable switch function at any time. The reed contact is adjustable over the full switching range of the meter.
