The AP7510 Frequency Scaler can be used to directly interface between totalizers and turbine flowmeters, magnetic tachometer sensors and other frequency transducers.
A continuously adjustable scaling factor (input-to-output ratio) of 0.00001 to 0.99999 is provided to precisely match the frequency transducer and totalizer.
The AP7510 provides a square wave output which can be used to drive electronic counters with TTL, CMOS, or 24 V inputs.
