ABSTRACT:
A probe system is provided which may be removably installed in-line in a pressurized pipe line to determine the pH of the fluid flowing therethrough. The probe system comprises a mounting means exteriorly secured to the pipe line, a valve means in said mounting means and a cap means secured to the mounting means and having an opening therein. An elongated pH probe is inserted through said opening and is secured by said mounting means while the probe tip is disposed within the pipe line. The probe includes a transducer for converting the acidity of the fluid flowing through the pipe line to an electrical signal representing the acidity, and a smooth, adherent plastic coating is provided on said probe to define an elongated sheath with a uniform, round circumference. A sealing means seals against the sheath to prevent fluid flow past the cap means, said sealing means permitting movement of the sheath relative to said cap means upon installation and removal of the probe within the pipe line.
