Description:
The flowmeter and switch model DS04 works according to a
modified variable area principle.
The float is guided in
an upward tapered measuring tube
. The
flowing medium moves the float in the flow direction. An
externally mounted pointer indicator is magnetically coupled
to the float and thus, following the float position, indicates the
flow rate on a scale.
A Reed contact is mounted outside the meter in a sealed
housing. When the float reaches the position of the Reed
contact the switch will close. With higher flows the float
moves further upward until it reaches 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 measuring and switching range of the meter.
Typical application:
The variable area flowmeters and monitors DS02 are used to
measure and monitor continuous flow rates of low-viscosity
liquids or gaseous media.
Areas of applications are:
•
cooling systems
•
engineering
•
medical technology
•
pharmaceutical and chemical industries
•
research and development
