Product Information

Comprehensive technical details and specifications for our industrial tank gauging solution

Product Description

MTG-FB-R5-XXX (where “XXX” is the overall probe length in inches, from 209” to 860”) is a flexible PVDF magnetostrictive tank inventory management probe which enables very accurate product level and measurement of as little as 1” (25mm) of water in the bottom of tanks. It also provides five temperature measurements spaced evenly 1m from the tank floor. This unique OMNTEC bottom reference design takes full advantage of the tank bottom stability versus known instabilities of a tank roof. The tank bottom reference design is further enhanced by a top mounted constant–tension feature. This feature maximizes the probe’s level accuracy to less than 0.01 of an inch by removing tank movements and its influence on measurement. In turn this OMNTEC exclusive design maximizes the operator’s ability to manage inventory with accuracy and confidence.
The MTG-FB-R5-XXX is typically installed on a 6” or larger process fitting. Other fitting may be accommodated. Please consult the factory for a detailed review of your unique application.
Numerous product float options are available, dependent on the density and composition of the tank product.
