Flowmeter with FP-CTR-500/502

Hi to all,

any people have experiencing for flowmeter with a counter NI FP-CTR-500/502,
its a right choice for mesureament from 4 to 400 GUS/h ?
Many thanks in advance for any indication.

Best regards.

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

Number of channels.......................... 12 (8 count, 4 gate)

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 V

OFF state

....................................≤6 V

Input 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
