The OleumTech® FT1 Wireless Flow Totalizer Transmitter is designed to work with virtually any third-party flow turbine meters for accumulating volume of liquid with high accuracy of ±0.01 %. Users have the ability to set the contract hour and set the flow rate to per second, minute, hour, or day. Users can also match the k factor and k factor units and display the volume output in barrels, liters, gallons, or cubic meters.

The FT1 provides a 2-pin pickup coil connector and a 1-inch mating union for connecting to a turbine meter.


The FT1 Wireless Transmitter relies on power from a replaceable battery. The system is engineered to achieve maximum battery life, providing over 6 years of life from a single battery.


Designed for use in Class I, Division 1 (Zone 0) hazardous locations. The FT1 is intrinsically safe, meaning it cannot a cause a spark and can be serviced without being removed from a process.


The FT1 features a 32-character local LCD display for instantly reading process data, battery voltage, and RF strength (RSSI). When the display is set to configuration mode, users can set all of its parameters and connect to a network just using the push button interface without the need of any configuration cables.


The OTC Sensor Network is managed using the BreeZ Software by OleumTech, provided free of charge. The Flow Totalizer Transmitter can be configured using the push button interface or BreeZ Software.


The FT1 Transmitter is one of many Wireless Transmitters that communicates with an OleumTech Wireless Gateway within its network, creating a highly scalable network, accommodating virtually any level or I/O requirement.
