The impeller flowmeters of the DR04 series consist of a sensor and an optional transmitter. The sensor has an impeller which is mounted in a housing made of PPS, PVDF, MS or stainless steel and is rotated by the flowing medium. Depending on the material version, this rotary motion is measured inductively or by a Hall sensor system and output as a flow-proportional frequency signal. A transmitter integrated in the housing with various output signals is optionally available for evaluating the signal.
Typical applications
The DR04 impeller flowmeters are a versatile measuring and monitoring system for all low-viscosity liquids, which do not attack the materials used, due to their design. The metal version allows high process pressures up to 100 bar, therefore the instruments can also be used under difficult process conditions.
