Level sensors receive software upgrade

Upgraded software for Mobrey MSP noncontacting ultrasonic level transmitters improves false echo detection.

Emerson Process Management has released software for its family of Mobrey MSP noncontacting ultrasonic level transmitters.

The upgrade features an enhanced false echo rejection capability which allows reliable operation in complex infrastructures where tanks and channels contain static obstructions such as stay bars, ladders or weld beads.

As a noncontacting technology, the ultrasonic sensors are suitable for use with a very wide range of liquids and chemicals, including frothy or agitated surfaces.

The new upgrade extends application of the transmitters to even the most demanding installations, for minimal downtime and maximum reliability.

The dead band of the transmitters has also been reduced to just 300mm, allowing users to fill tanks to a higher level and to optimise accuracy in open channel flow applications.

The MSP range comprises three models which are available with HART communications for integration into a plant-wide control system.

The entry-level MSP422, for use in safe areas, has an operating range of 8m and the MSP400 has a range of 11m.

Mobrey MSP level transmitters are part of the Emerson's PlantWeb digital plant architecture that improves plant efficiency through asset optimisation, process automation and management execution.
