Emerson’s new high-performance version of its Rosemount™ 3308 Guided Wave Radar (GWR) Wireless Level Transmitter is the first standalone WirelessHART radar level device to comply with the API 18.2 custody transfer standard. The transmitter delivers enhanced accuracy which can be verified without having to open a tank’s thief hatch, thereby increasing safety.

API 18.2 places strict accuracy demands on level measurement instrumentation because high levels of uncertainty during custody transfer can have significant financial implications. An upgraded microwave module makes the Rosemount 3308 more tolerant to difficult process conditions and able to deliver a more sensitive and repeatable measurement and higher accuracy.

Accuracy can be easily and quickly verified using the Rosemount VeriCase mobile verification tool. This straightforward procedure does not require a tank’s thief hatch to be opened or any product to be transferred, making it an important safety improvement.

In addition to providing the accuracy required for custody transfer applications, the Rosemount 3308 also delivers reliability in continuous level and interface monitoring applications in refineries, oil fields, offshore platforms and chemical plants, thereby providing a cost-effective standardized solution across an entire facility.
