Works with a Third-Party Turbine Flow Meter

The OleumTech® OTC Wireless Flow Totalizer Transmitter is designed to work with virtually any third-party turbine flow meters for accumulating volume of liquid with high accuracy of ±0.01 %. You can set the contract hour and set the flow rate to per second, minute, hour, or day. You can also match the k factor and k factor units and display the volume output in barrels, liters, gallons, or cubic meters. The WT-FT1 provides a 2-pin pickup coil connector and a 1-inch mating union for connecting to a turbine meter. This ultra low-power transmitter is powered by a replaceable battery pack that provides up to a 10-year life. The push button LCD interface allows for device configuration and instant access to process data.

Reliable, Scalable and Safe

The field-proven wireless transmitter communicates with an assigned wireless gateway within the OTC Wireless Sensor and I/O Network creating a highly scalable network, accommodating virtually any I/O requirement.

The OleumTech wireless transmitter is certified for use in Class I, Division 1 (Zone 0) hazardous locations. It is Intrinsically Safe, designed not to cause a spark, and can be serviced without being removed from a process.
