System Check-In Period
This setting controls how often the node will read the Modbus device and forward the register data to
the gateway.
Modbus Slave ID
The Modbus Slave ID must be set with the SignalFire Toolkit. Each remote device connected to a
SignalFire Gateway must have a unique Modbus Slave ID.
Turbine Meter Connection
The Flow Totalizer is supplied with a 1” NPT Union to allow it to be directly mounted to a standard
turbine flowmeter. The nut on the union can be loosened to allow the totalizer to be rotated to the
desired orientation. Also supplied is a 2-pin connector for connection to the turbine flow meter
magnetic pickup. Teflon tape should be used on the NPT connections.
Pickup Sensitivity Selection
For most turbine flow meters, the gain selection jumper should remain in its default “LOW GAIN”
position. This provides a sensitivity of 20mV p-p. If a high sensitivity is needed the jumper can be
moved to the “HIGH GAIN” position which increases the sensitivity to 5mV p-p.
