Abstract
A system for real-time monitoring of steam lost from steam traps that integrates a series of sensors to measure pressure and temperature, configured to monitor leaks from any type of steam traps integrated to a wireless communication module that has a microcontroller and an algorithm specially developed for the control of such leaks by means of automatic machine learning.
Claims10
A system for real-time monitoring and control of steam lost from steam traps, the system comprising:
- at least two ultrasonic sensors for pressure measurement;
- at least two temperature sensors;
- a steam trap;
- at least one ultrasonic microphone positioned in contact with the steam trap;
- and
- a connection module connected to the at least two ultrasonic sensors and the at least one ultrasonic microphone, the connection module comprising a microcontroller and a wireless communication module,
- wherein the microcontroller is configured to:
- analyze a signal from detected variables received by the at least two ultrasonic sensors,
- check a trap status and calculate an amount of steam lost,
- diagnose whether the steam trap has any type of leak or fault selected from a closed fault, an open fault, a partial leak, or a fast leak, and
- report on a platform every certain period of time according to steam trap specifications and the trap status.
8 more elements
A method for real-time monitoring and control of steam lost from steam traps, the method comprising:
- collecting measured data from an ultrasonic microphone at a certain instant of time;
- transferring the measured data to a microcontroller that is programmed via an algorithm to convert the measured data from the ultrasonic microphone to a frequency domain and compare data with that of a good condition steam trap to make an initial calculation and classify a fault as open or closed;
- checking whether a state corresponds to an open fault based on detected variables;
- checking whether the state corresponds to a closed fault based on the detected variables;
- checking if the state corresponds to a partial failure based on the detected variables;
- checking whether the state corresponds to a fast fault based on the detected variables;
- calculating an amount of steam lost and an amount of gases emitted or saved;
- and
- reporting trap status in real time to a platform or storage unit.
