ABSTRACT:
This disclosure sets forth a fluid flow line which extends at one end from a fluid source at a pressure to be measured comprised of fluids contained within a well borehole, and the fluid flow line has a "J" shaped component to trap debris and trash to prevent it from flowing the full length of the fluid flow line and contacting a pressure transducer. The flow line is further defined by the threaded connection of two structural components making up the sonde wherein the components thread together and threads are sufficiently spaced apart to form an elongate helix as part of the flow path.
