The DK 32 variable area flowmeters are versatile and can be used for gases and liquids.

The sturdy all-metal design ensures high resistance to pressure, temperature and media and stands up to extreme application and environmental conditions.

The position of the float is magnetically transmitted to an analog indicator to display the measured value. No power supply is necessary.
