MULTI-SENSOR HYDROSTATIC GAUGE FOR FUEL STORAGE TANKS

摘要

A probe rod (19) is provided with sensor housings (40), pipe sections (20), and joint sleeves (30) all having a common outer diameter. The sensor housings (40) and joint sleeves (30) are threadably connected to the various pipe sections (20). The threadable connections have a double seal using an O-ring and a threading paste that ensure a gas tight seal while being easy to assemble. Pressure and temperature sensors are mounted within the sensor housings (40). Output leads from the sensors are threaded through the pipe sections (20) and through throughways in the sensor housings (40) and joint sleeves (30) to a circuitry box (45) mounted on the top of the probe rod (19). The circuitry box (45) contains electronics for processing signals generated by the sensors and for transmitting the results to a remote location.
