Claim:
1. A fluid filtering device comprising: a casing with a chamber; at least one fluid filter disposed in the chamber of the casing and including a filter space, an input hole in communication with the filter space, and an output hole in communication with the filter space, a filter assembly disposed in the filter space and connected to the output hole, and a discharge hole in communication with the filter space; an input pipe disposed in the casing and including an input passage, an outer input end which is in communication with the input passage and located outside the chamber, and at least one inner input end which is in communication with the input passage and connected to the input hole of the fluid filter; an output pipe disposed in the casing and including an output passage, an outer output end which is in communication with the output passage and located outside the chamber, and at least one inner output end which is in communication with the output passage and connected to the output hole of the fluid filter; an input pressure gauge including an input gauge head which is disposed on the casing and located outside the chamber, and an input tube which is disposed between and in communication with the input gauge head and the input passage to detect the pressure of the input passage, and the detected pressure of the input passage being displayed on the input gauge head; an output pressure gauge including an output gauge head which is disposed on the casing and located outside the chamber, and an output tube which is disposed between and in communication with the output gauge head and the output passage to detect the pressure of the output passage, and the detected pressure of the output passage being displayed on the output gauge head; and an automated fluid drain controller being disposed in the chamber of the casing, and including a control input end which is in communication with the discharge hole of the fluid filter, and a control output end which is located outside the chamber; wherein the chamber is defined by a plurality of plates, the outer input and output ends of the input and output pipes, the control output end of the automated fluid drain controller, and the input and output gauge heads are all mounted on the same side of the casing on the outer surface of the same plate, the input gauge head is adjacent to and at the same level as the outer input end of the input pipe, the output gauge head is adjacent to and at the same level as the outer output end of the output pipe, the input gauge head and the outer input end of the input pipe are not located at the same level as the output gauge head and the outer output end of the output pipe.
