More informations

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 applications

The variable area flowmeters and monitors DS04 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
