Hi adrtab5,
I'm not sure about what GUS/h means. Looks like a sort of "rotation rate" something like rpm but slower.
Anyway you can find information about 500/502 specs on this KB Measuring Frequency With the FP-CTR-500/502
And obviously in the manual FP-CTR-500 and cFP-CTR-500 Operating Instructions.
You should see if the specification of the CTR-500 match your needs, namely the specification of your flowmeter.
Here's an extract.
Input Characteristics
Input type..........................................10–30 VDC sinking,
compatible with most 12 and
24 VDC devices
Maximum input voltage....................30 VDC
Input threshold level
ON state
......................................≥10 VOFF state
....................................≤6 VInput current limiting........................5 mA maximum
Input bandwidth
Count inputs ...............................50 kHz; 200 Hz with
software-enabled lowpass
filter
Gate inputs..................................50 kHz
Maximum off-state leakage
current for external devices...............0.2 mA
Best Regards
