Systems, methods, and media for generating alerts of water hammer events in steam pipes

A method of generating an alert of an event in a steam pipe, comprising:

• obtaining temperature measurements of the steam trap;
• sampling an accelerometer coupled to a steam pipe to provide accelerometer data;
• determining that the accelerometer data meets or exceeds a threshold using a hardware processor;
• in response to the determining that the accelerometer data meets or exceeds the threshold:
• increasing the sample frequency at which the accelerometer is sampled;
• and
• sampling an ultrasonic sensor to provide ultrasonic sensor data;
• detecting a failed closed steam trap by detecting no accelerations in the steam trap, detecting decreased ultrasonic noise based on the ultrasonic sensor data, and detecting a drop in temperature of the steam trap;
• generating an alert that of the failed closed steam trap;
• receiving a plurality of alerts that a water hammer event has occurred;
• determining that a period of time has passed since a first of the plurality of alerts was received;
• and
• in response to determining that the period of time has passed, comparing data from multiple sensor modules to identify one of the multiple sensor modules that is closest to the water hammer event.
