Variable-area flowmeter DS02 series

for gasfor liquidsbrass

The flow switch model DS02 works according to a modified variable area principle. The float is guided in a cylindrical measuring tube by means of a spring. The flowing medium moves the float in the flow direction. A Reed contact is mounted outside the meter in a sealed housing. This reed contact is encapsulated in a continuously adjustable housing and thus protected from external influences. 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. An external pointing instrument is magnetically coupled to the float and indicates the flow rate. Typical applications 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 research and development ow cost version for monitoring the flow of low viscous liquids or gases small installation dimensions material: brass or stainless steel for pipe sizes from 1/4" to 1" any mounting positon with switch contacts, analogue transmitter and/or display
