Tank fuel and water level from one sensor

Simultaneous loop powered measurement of surface and interface level in a tank, using guided wave radar technology, is available with a simple small probe from Rosemount

Quite simply the most sophisticated, loop powered radar transmitter today, the Rosemount 3300 allows simultaneous interface and level measurement in a process tank: it is a MultiVariable transmitter.

Using guided wave radar technology, a microwave radar pulse travels down through the tank, along a simple probe, and receives reflected signals from liquids or solid materials surrounding the probe.

A portion of this pulse is reflected at any interface, when the probe is surrounded by materials of a different dielectric constant.

Probe designs are available as rigid or flexible conductors that can be cut to length on site.

These probes are suitable for use in long nozzles, with small fittings/flanges, or in narrow bridles on separators.

The modular construction of the Rosemount 3300 allows the head electronics to be detached, freely rotated, or replaced without opening the tank.

Above all, the single, small diameter penetration for level and interface measurement makes a simple and inexpensive installation.

Advanced signal processing gives higher resolution and more reliable measurements in applications where other styles of transmitter fail.

Turbulent or agitated liquid surfaces, contoured or sloping solids surfaces, or with dusty or steam laden vapour spaces - these are the applications where the 3300 thrives.

Guided wave radar can also cope with probe coating and material build-up better than other contacting level technologies, using the echo characterisation available within the digital signal processing.

The Rosemount 3300 is a two-wire, loop powered transmitter, which can be retrofitted onto existing loop cabling, and used as a straight replacement of existing 4-20mA level transmitters, whether on a separator unit, an LPG/ammonia storage tank or a powder silo.

Being an intelligent MultiVariable transmitter, further benefits arise within PlantWeb digital plant architecture, using HART or Foundation fieldbus communications, when both surface level and liquid/liquid interface level can be monitored simultaneously.

The Rosemount 3300 is AMS Aware, compatible with the requirements of modern digital plant control systems, and is available as intrinsically safe or explosion-proof, built to the industrial standards and capable of the performance you expect from Rosemount products.
