Abstract
An apparatus for inserting and removing a sensor into and from a hot tap on a fluid conveying pipeline includes a pair of parallel threaded drive rods interconnecting a sensor plate and a mounting plate which are operatively connected to the sensor and the hot tap, respectively. The drive rods are interconnected by a sprocket and chain system which rotates the opposite drive rod in reaction to rotation of either drive rod. Load indicators are installed on the drive rods to assist the operator in correctly positioning and loading the sensor in the pressurized pipeline. The drive rods are connected to the sensor plate through moveable threaded sleeves which accommodate irregularities in the drive rod.
