Figure 14. Isolated Output Option Wiring Diagram
NOTE:
Follow the wiring diagrams in Appendix A to reconnect the existing flow element to the
replacement GF series flow transmitter, and to install a jumper on the flow element terminal
board if applicable.
The LT analog series flowmeters can be fully upgraded to the GF series flowmeters by replacing the LT
series transmitter with a properly calibrated GF series transmitter. The flow elements are the same except
for wiring differences at the flow element. The analog outputs also change locations. Jumper wire is
added from terminal 2 to terminal 4 of the flow element head terminal block. New connectors will need to
be installed on the transmitter for power, relays, flow element and analog output.
