The intrinsically safe flow transmitter forwards flow data wirelessly anywhere in the world with an Internet connection. When integrating AW-Lake’s TRG turbine or JV-CG or JV-KG positive displacement flowmeter with a SignalFire Sentinel radio node, this wireless flowmeter works in a mesh network to send data via Modbus to a gateway, where it is transferred to a PC, PLC or other control system. Wireless radio nodes install themselves automatically in the network and adapt to changes such as data volume, radio transmission conditions and power source conditions. ISM bands sustain radio signal strength through terrain, structures or weather for a range of up to ½ mile.
