More informations

The Flowmeter DS25 work according to the proven variable area principle. The float is guided in a conical 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. This indicator assembly is equipped with a scale calibrated to the operating conditions in the system and additionally may contain alarm contacts or an analogue output.

Typical applications

The variable area flowmeter model DS25 is used for measuring and monitoring the flow of all kinds of liquids or gases.

By using only stainless steel 1.4404 for the wetted parts the meter is especially suited for aggressive media.
