Flow Turbine Pickoff

Smart-Pickoff ASP Series
Calibrated frequency output (TTL)
Identifi cation memory

Functional description

DDM Smart-Pickoff ASP series is an intelligent pickoff for speed sensing of flowmeter turbine blades. Suitable mounting kits are available for easy installation to almost any flow turbine meter. The ASP housing is extremely miniaturized to fit even at applications where space is limited. The electrical connection comes with a high temperature cable and freely adjustable orientation. Turbine speed is detected without drag and converted to a high level digital TTL output. The ASP requires a DC supply voltage to operate. Carrier frequency amplifiers commonly used to run turbine flow meters are no longer required to perform a flow meter traceable calibration. A fast response temperature probe is providing media temperature readings for viscosity correction. Flow Turbine parameters and calibration data are stored in an internal memory. Combined with the intelligent VCA and VCA-T flow computer series we got self-parameterizing flow measurement systems which are linearized and viscosity corrected.
