Figure 7.22 Obtain Flow Coefficient
The flow coefficient can be obtained from the transmitter (input selection: sensor data or
simulated data). The above flow coefficient window is displayed when sensor data is selected.
Execute flow simulation for confirmation of configured flow parameters. Input differential
pressure, static pressure (absolue) and temperature value and confirm that desired flow is
obtained.
When the simulation is executed, it is necessary to connect RTD or mock resistance (about
100Ω) to the transmitter.
Once selecting “simulated value” and press the [Execute] button, the transmitter is transferred
to simulation mode. The transmitter will remain in the simulation mode for approximately 10
minutes and automatically return to normal mode. (Regarding the simulation duration time, refer
to User’s Manual IM 01C25R02-01E “EJX910A and EJX930A Multivariable Transmitter HART
Communication Type” and IM 01C25R03-01E “EJX910A and EJX930A Fieldbus Communication
Type”)
Press [Simulation off and close] button if you wish to finish the simulation mode immediately.
