Wireless Instrumentation
Totalizer/Flow Meter Turbine Head

 
The wireless turbine meter interface is a key component of DataPORT™ wireless monitoring systems. The wireless Turbine Flow-meter provides wireless access to a proven flow measurement technology that can be applied to a wide variety of liquid and gas applications. It is available with or without the turbine meter itself and with a selection of intrinsically safe pickups compatible with flow elements from virtually every major manufacturer.

Each field unit is self-powered and contains a magnetic pickup, signal conditioning circuitry, and an RF transceiver. Pulse data from the pickup is monitored, converted to a rate and total in user defined units. This information is transmitted to the Base Radio for centralized monitoring and data collection. Updates between once per second and once per minute may be specified. The RF base station and Field Units operate in the 902 MHz to 928 Mhz license free band making the installation and maintenance easy and worry free.
