This tech note describes the process to connect an EDD 860 Explosion Proof Totalizer with a Rapidlogger system.
The counter outputs on the EDD 860 Explosion Proof Totalizer needs pull up with a 10k resistor to enable them to generate outputs. are of the passive type.
Rapidlogger Quadrature input then the connection should be wired as shown in table 2.

The setting in the flowmeter totalizer can be adjusted from the front panel of the totalizer or via Modbus along with the Fluidwell Remote Configuration Utility.
Pulse Output value is 0.001 on the EDD flowmeter totalizer
Since this value is in bbl/pulse we multiply it by 60 (seconds) to obtain bbl/minute. So the value you enter in the Multiplier field of the Rapidlogger utility is 0.06000.
