Vortex flow meter
Thread Content
When the value displayed by the vortex flow meter does not match the value on the measuring instrument, should we use an current calibration code? ? Is there a professional explanation for the current output load of 600 ohms and the pulse output load of 3–30V in vortex flowmeters? ? Thank you
Check whether the ranges on both sides are the same. Check whether the flow rate corresponding to the current is correct
The display panel of the vortex flow meter allows for configuration of the way in which data is displayed; check the manual to find out whether it shows instantaneous flow rate or standard cubic values, etc. The range mentioned above also needs to be consistent with the range displayed on the remote end. The resistance value mentioned in the current signal refers to the load that the circuit can handle; the resistance of this load must not exceed a certain limit. The pulse load refers to the maximum voltage level that the contacts of a digital switch can withstand; in other words, the contacts of a relay are only capable of withstanding a voltage level of 220VAC, and not more than 300V.
