System Conguration for Digital Output (DE Output)
System conguration
Figure 1-5 shows a system conguration in which the ow rate measured by the
unit, the database in the unit, and self-diagnostics are output using the DE (Digital
Enhancement) protocol (rules for digital signal communication).
In this system, the DE protocol-based digital signal transmitted from the unit is
output to the control system after conversion to an analog signal at the smart protocol
converter (SPC). Or, the digital signal is directly transmitted to the control system, if
it is capable of receiving the DE protocol-based signal directly.

Smart Electromagnetic Flowmeter (device)
Measures ow rate and outputs the instantaneous ow rate and unit self-diagnostics
using a digital signal.
Smart protocol converter (SPC)
Converts the DE protocol-based digital signal into a 4 to 20 mA or 1 to 5 V DC
analog signal for output.
Smart handy loader (SHL)
Used to change the SPC settings.
Smart communicator (SFC)
• Used to communicate with the device to read data and change the device settings.
PM100
• Simultaneously executes such functions as process control on the UCN, regulatory
control, sequencing, calculation, and process input/output.
