4. Enter the reference temperature for the Linear expansion coefficient.
5.
Enter the Pressure expansion correction if desired.
Configure meter pressure expansion corrections
1. Enable Live or Fixed for Pressure for meter corrections and Pressure expansion
correction on the Field Setup Wizard Startup page.
2. Enter the outside diameter of the meter body.
3. Enter the Young's Modulus value (ratio of tensile stress to tensile strain).
4. Enter the Poisson's Ratio value (the absolute ratio of the pipe material lateral strain
over axial strain).
5. Click Next until the Finish button displays in the Field Setup Wizard to write the
corrections to the meter.
Pressure and temperature data updates
The Daniel 3810 Series Liquid Ultrasonic Flow Meter samples the input analog signal(s) and
updates the corresponding data point(s) (LiveFlowPressure, LiveFlowTemperature) once
per second regardless of the input selection (disabled, live, or fixed).
Every five seconds, the meter updates the “in-use” flow-condition pressure and
temperature values (FlowPressure, AbsFlowPressure, FlowTemperature) depending upon
the input selection, validity of the input data, and the selected data source upon alarm.
