Abstract: A sensor assembly for monitoring any fluid accumulation, temperature, and other properties, characteristics and conditions of the fluid in the dry portion of a life safety fire sprinkler system. The sensor assembly includes a sensor receptacle, an initial fluid level accumulation sensor, a fluid temperature sensor, and at least one upper fluid level accumulation sensor. The sensor assembly can transmit data in real time through a transmitter assembly to a controller and based upon programmed criteria and interact in real time, with other devices. For example, if the sensor assembly detects an amount of condensed fluid in the system and a temperature of the condensed fluid is below a programmed value (e.g., ?38.0° F.), the system can send an alarm in real time that the system could be experiencing a potential fluid freezing event which could be detrimental to the sprinkler system.

Abstract: A sensor assembly having a sensor reservoir with probe for fire sprinkler and other systems to monitor and measure the internal characteristics of a pipe system wherein the sensor reservoir is directly connected to the pipe system, allowing the sensor reservoir to fill with the fluid contents of that system and to have a probe be in direct contact with the fluid contents of that system without altering the fluid flow dynamic within the piped system. The probe can transmit data to a controller and, based upon programmed criteria, interact with other devices, e.g., if the temperature probe reports a low temperature of the internal fluid characteristics, the controller can activate a heater linked to the controller so that pipes or sprinkler heads will be further resistant to freezing or other compromising conditions.
