Method 2: Involves the conversion of the existing sensor calibration number / meter
factors to an equivalent Rosemount 16-digit calibration number. Accuracy of the
meter using this methodology is estimated to be in the range of 2-3%. Contact the
Rosemount technical support for more information on this method or to determine
a calibration number for the existing sensor.
Once these steps are completed, the meter will begin measuring flow. Verify the
measured flow rate is within the expected range and that the output correctly corresponds
to the measured flow rate. Also verify the reading in the control system matches the
reading at the transmitter. Once these items have been verified, the loop can be placed
into automatic control as needed.
D.3.1
Universal trim
The universal auto trim function enables the transmitter to determine a calibration
number for sensors that were not calibrated at the factory. See
D.4
Wiring the universal transmitter
The wiring diagrams in this section illustrate the proper connections between the
transmitter and most sensors currently on the market. Specific diagrams are included for
most models, and where information for a particular model of a manufacturer is not
available, a generic drawing pertaining to that manufacturer's sensors is provided. If the
manufacturer for the existing sensor is not included, see the drawing for generic
connections.
Any trademarks used herein regarding sensors not manufactured by Rosemount are
owned by the particular manufacturer of the sensor.
