Let me know first which make you have.
Instrument have min and max ranges on its name plate.
So wiht multimeter you can check 4-20ma of flow meter.It
must be 4 ma if flow is zero and 20ma if flow is max range.
supose your flow mete got 100L/hr.
for 4ma flow should be 0 L/hr
8ma - 25L/hr
12ma - 50L/hr
16ma - 75L/hr
20ma - 100L/hr
Like this you can check.
