Hello,
I am commissioning an ABB VFD ACS255 IP20 model. According to the manual the input is 120VAC 1PH and the output is 230VAC 3PH.
I have it wired to a Baldor motor that is 230V, 3PH and 60Hz.
I have the VFD configured with the motor specifications.
When I try to start the motor on...

I am looking for an analyzer capable of detecting traces of H2SO4 in a gas sample (ABB, Emerson, Yokogawa, MT, ThermoFisher, Siemens, etc.)
I have looked all over the place and I can't seem to find one, or at least the datasheets don't mention H2SO4 detection.
Does anybody have a...
Analyzer Technologies
I am putting together a table for quick reference on analyzer technologies used in the oil and gas process industry.
I would like some advice from the community to review the accuracy of the table and potentially add any technology that I may have missed.

Hello,
Currently working on the selection of a flow meter to measure a flow mix of water+amine+CO2.
I am currently considering Coriolis as the first option yet I have some lines larger than 16" and it's not economically attractive to use Coriolis for this applications.
I have done some...
