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. A 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.
Note: Follow the following wiring diagram 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.
