Figure 2-12: X144 e-FlowMeter Cable Options
1) Connect the wire marked “4-20mA” to the proper recording/measurement device. Connect that
device per manufacturer’s recommendations. If no logging/DAQ/SCADA system is available,
attach the “4-20mA” wire to the ground of the power supply.
2) Connect the wire marked “24 VDC” to either 12 VDC or 24 VDC, as available.
3) If possible, use handheld multi-meter to verify mA readings prior to leaving installation.
a) When there is no flow present, the X144 e-FlowMeter should read very close to 4.0 mA.
4) A possible power supply for the X144 e-FlowMeter is the Cla-Val X143MP Micro Turbine Power
Generator. (See Figure 2-16, Page 14)
Note:
AC/DC converters must be properly grounded in order to prevent electronic noise.
