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, measuring accumulated flow rates and volume. 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.

This product is also available as local read (standalone).

This product is also available in RS485 Modbus.
