The Magne-Trac Plus combines a Magne-Trac magnetic level indicator with a Bridle-Trac bypass chamber, in which a customer specified guided wave or non-contact radar may be installed. Although either instrument may be connected to the vessel, Questtec recommends that the bridle functions as the primary chamber. By using the magnetic gauge as the secondary chamber, the customer will have the option to rotate the indicator up to 180 degrees easily in the field. The two chambers may welded or flanged together; QTS recommends installing valves in between the magnetic gauge and bridle chamber so one may be isolated if necessary.
