Collaboration introduces new intrinsically safe wireless flow transmitter

AW-Lake Company, in collaboration with SignalFire Wireless Telemetry, has introduced an intrinsically safe wireless flow transmitter that wirelessly forwards flow data anywhere in the world with an Internet connection. Integrating AW-Lake’s TRG turbine or JV-CG or JV-KG positive displacement flow meter with a SignalFire Sentinel radio node, this innovative 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 half a mile. Ideal for applications with a limited power source or not power at all, the device incorporates an internal high capacity lithium battery that powers the passive inductive flow sensor and radio node for years, 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 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.
