IMPORTANT  NOTICE

This manual will assist you in operating and maintaining the GPI 

electronics supplied with your GPI meter. The GPI Electronics 

can be used in indoor or outdoor applications where occasional 

exposure to moisture is common.
The GPI 4-20 mA Out with Display is a flow totalizer and rate 

meter with industry standard current loop output. The unit is 

loop powered, and provides a 4-20 mA analog output propor-

tional to the frequency signal for communication with PLCs and 

other customer equipment. The 4-20 mA (or 0-20 mA) output is 

calibrated under actual flow conditions with simple push-button 

calibration. Auxiliary output includes 0-5 VDC.
The  microprocessor-based  electronics  have  extremely  low 

power  requirements  and  are  completely  powered  by  the

4-20 loop. The electronics provides the options of local (on the 

meter) and/or remote (up to 5,000 feet) display. Flow total and 

rate are displayed on a large 6-digit LCD readout with two-point 

floating decimal for totals from .01 to 999,999. All operations are 

easily accessed with the push buttons on the display front panel.

This unit is not FM Approved. 

NOTE:  This unit is loop powered, requiring an input power sup-

ply of 8.5 to 35 volts (24 VDC is recommended). 

NOTE:  Setpoint calibration of the unit is required for the 4-20 

mA, 0-20 mA, and 0-5 V output options.

•  This product is not approved for use in hazardous locations.
•  When  applying  external  power  to  the  transmitter,  use  DC 

power only.

•  Disconnect external power to the transmitter before detach-

ing or attaching input or output wires.

•  Ground loops between sensor and user equipment can dam-

age the transmitter and can be dangerous.

•  If  you  cannot  galvanically  isolate  the  sensor  from  earth 

ground,  you  may  need  to  use  the  transmitter’s  optically 

isolated inputs.

•  Be sure O-rings and seals are kept in good repair. 

Installation should be performed only by qualified person-

nel, and in accordance with local governing regulations.
