No it wont damage

Thank you for your question. Yes, you can use a 375 Field Communicator for calibration but you cannot use a 375 for a flow configuration.

Yes.

Thank you for your questions Madhu. - The square root option is not available in the 3051SMV because the transmitter includes a flow computer, therefore it is calculating the compensated flow value. The flow computer already applies the Sq. Rt. Term in its flow calculation. - Nm3/hr although it sounds like it would be a volumetric measurement, it actually requires a mass flow calculation. The Nm3 has a specific mass, so there is a specific relationship between mass and the term Nm3/hr. It is not a volumetric calculation. - The reason that your flow rate is not what you expected when applying 159 mbar of DP is that in a benchtop setup the transmitter is treating the 159mbar of DP applied as both a static pressure and differential pressure reading. What this means is that the transmitter is reading a very low amount of static pressure or line pressure which is causing the flow rate output to be very low. I would recommend that you apply 159 mbar of DP to the sensor and just observe the digital value of measured DP, that will confirm for you that the DP sensor is accurate. If you would like to compare the flow rate output for various conditions you may use the test calculation feature that is available with the Engineering Assistant software or on a handheld HART communicator. The Test Calc function will allow you to enter a specific DP, a specific absolute pressure for line pressure, and a temperature value, then the transmitter will calculate the correct flow rate for that scenario.

You don't zero out the offset from the remote seal. You re-range the transmitter to account for the zero suppressed zero. if you need to adjust the calibration you use the low trim and high trim, not the zero. You can setup the display separately with scaled variable to display positive zero based values.

A zero trim is a single-point offset adjustment of the transmitter output. A zero trim should be performed after every installation once the transmitter is in its final mounting position in order to compensate for mounting position effects.
