A common development of AW-Lake and Signal Fire takes flow data measurement into the wireless era - all while providing Intrinsically Safe transmission: Integrating AW-Lake’s TRG turbine or JV-CG or JV-KG positive displacement flow meter with a Signal Fire Sentinel radio node, the new wireless flow meter 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.
The 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 a ½ mile. Ideal for applications with a limited power source or not power at all, the transmitter incorporates an internal high capacity lithium battery that powers the passive inductive flow sensor and radio node for yearss, even in low temperatures. The flow transmitter can be configured for check-in intervals between five seconds to one hour to save battery life. Flow rate and total data configurations are available.
Eliminating the need for expensive cabling, the Wireless Flow Transmitter installs anywhere in minutes with an easy thread-installation. Units cost less than running 60 feet of conduit. Featuring an intrinsically safe design, units operate in hazardous areas where hostile or volatile materials and liquids exist.
