A probe rod is provided with sensor housings, pipe sections, and joint sleeves all having a common outer diameter. The sensor housings and joint sleeves are threadably connected to the various pipe sections. The threadable connections have a double seal using an O-ring and threading paste that ensure a gas tight seal while being easy to assemble. Pressure and temperature sensors are mounted within the sensor housings. Output leads from the sensors are threaded through the pipe sections and through throughways in the sensor housings and joint sleeves to a circuitry box mounted on the top of the probe rod. The circuitry box contains electronics for processing signals generated by the sensors and for transmitting the results to a remote location.

[ What is claimed is:] [1.] A probe with no moving parts, for use in above and below grounds a liquid tank having a floor and walls, capable of continuous measurement of a liquid while emersed in that liquid, wherein said probe comprises:at least two pipe sections a first section and a second section, each of said pipe sections detachable connectable to the other, wherein each has a top end and a bottom end and each pipe section has an outer diameter which is equal to the outer diameter of the other section, thereby providing a smooth exterior surface when the at least two pipe sections are detachably connected together;at least one connector connecting said pipe sections, said connector constructed and arranged to connect said top end of said first pipe section to said bottom end of said second pipe section to form a probe rod having a common outer diameter further said connector having a channel to provide contact with liquid from said tank to one of at least two sensors, a first sensor and a second sensor;a first sensor, contained in the probe rod capable of continuous temperature measurement through direct contact with the liquid, and a second sensor contained in the probe rod capable of continuous pressure measurement through direct contact with the liquid, and wherein said first sensor for continuous pressure measurement has a diaphragm which is oriented so that the sensing side of said diaphragm is horizontally to the probe and oriented towards the floor of the tank;means for controlling the first and second sensors to produce output signals; andmeans for compiling the output signals and transferring the compiled data to another device.
