Variable-area flowmeter DS05 series

horizontalverticalglass

The flowmeter and switch model DS05 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 a burnt-in scale on the measuring glass. 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 switching range of the Typical applications The variable area flowmeters and monitors DS03 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 for measurement and monitoring of low viscous liquids horizontal or vertical mounting material: brass or stainless steel for pipe sizes from 1/4" to 1 1/4" with switch contacts and/or analogue transmitter
