Systems and methods for accessing and monitoring a fluid within a pressurized pipe
Systems and methods for accessing and monitoring a fluid within a pressurized pipe include a nozzle coupled to a section of the pressurized pipe and defining an open proximal end fluidly communicating with the pressurized pipe through an access hole formed in the pressurized pipe, an open distal end, and an interior passage extending from the open proximal end to the open distal end. A cover plate is coupled to the open distal end of the nozzle. A valve element is disposed in the interior passage and movable between an open position, in which the valve element is entirely disposed within the nozzle, and a closed position, in which a proximal section of the valve element is disposed in the pressurized pipe. A sensor port extends through a proximal end of the nozzle and positioned to fluidly communicate with the interior passage when the valve element is in the open position.
