An assembly for sensing flow material in a passage of a member is disclosed. The assembly has a housing, a communication device disposed at least partially in the housing, and a controller disposed at least partially in the housing. The assembly also has a sensor array disposed at least partially in the housing, and an external-surface-mounting attachment portion configured to non-intrusively attach the assembly to a surface. The sensor array includes a pressure sensor, a density sensor, a corrosion sensor, and a vibration sensor. The controller controls the communication device to transmit sensed data collected by the sensor array at a frequency of between about one transmission per second and about fifty transmissions per second. |
