Anybody know offhand if it uses actual pressure transducers in D-P operation or if they are using those half baked impellor speed versus current draw calculations?

I'm thinking they do but can't remember for sure.

    From the Data Booklet:
    Differential-pressure and temperature sensor
    The MAGNA3 incorporates a differential-pressure and temperature sensor. The sensor is located in the pump housing in a channel between the suction and discharge ports. The sensors of twin-head pumps are connected to the same channel and the pumps therefore register the same differential pressure and temperature. Via a cable, the sensor sends an electrical signal for the differential pressure across the pump and for the liquid temperature to the controller in the control box. In case of missing sensor signal, the pump will run at maximum speed. When the fault has been corrected, the pump will continue operating according to the parameters set. The differential-pressure and temperature sensor offers substantial benefits:
    • direct feedback on the pump display
    • complete pump control
    • measurement of the pump workload for precise and optimum control resulting in higher energy efficiency
