The system also includes one or more processors configured to: initialize a plurality of status words according to the TRTP, generate a payload array configuration having a number of payloads in a payload array and a number of registers, generate the payload array having hose test result information according to the TRTP, and provide the generated payload array to the network interface for transmission.

The present invention relates generally to a device which is directed toward a compact, portable, lightweight and modular device for the integrity testing of equipment to determine fluid pressure, temperature and flow rates at specific locations throughout a system. The present invention provides the ability and capability to acquire data via immediate, intermediate or distanced pressure and temperature monitoring, observation and collection. Said results may be directly monitored, at an immediate, intermediate or distanced proximity, and thereby collected and digitally stored and/or transmitted, via real-time data collection and transmission, to an on-site or off-site operator or manager for remote active or passive data collection, data monitoring, data analysis and data management.
