Systems and methods for components, e.g., liquid or gas handling, are described. A tester includes a wand that is handheld that can communicate with a handheld electronic device which in turn can communicate with a central monitor for storing and compiling readings as historical profile data. The wand includes an acoustic probe to physically contact the device to acoustically sense the performance of the device. The acoustic probe includes a probe tip and a stack of acoustic elements, an electrode, a stack mass, and a head to convert the acoustic signal into an electrical signal. The tester can include onboard force sensors associated with the probe or a temperature sensor. The tester or a handheld device includes circuitry to process the information, interact with the user, and transmit information to and from the handheld electronic device and/or the central monitor.

According to one aspect of the disclosure a steam trap system and a method of operation is provided. The steam trap system includes a steam trap body and a disk operably coupled to the steam trap body, the disk being made from a magnetic material. A cap is coupled to the steam trap body adjacent the disk, the cap being made from a nonmagnetic material. A hall effect sensor operably coupled to the cap, the hall effect sensor being configured to generate a signal in response to movement of the disk.

The present invention includes a threshold value calculation unit that calculates a normal range that is a range of values that are taken when a steam trap is in a normal state, by using a predetermined calculation reference, based at least on state values with normal determination results, from among state values that have been stored in the storage unit during a predetermined period. A determination unit can perform predictive determination to determine whether the steam trap is in a normal state or a state that indicates an inclination toward a bad state and is highly likely to change to a bad state, by determining whether or not the state values are in the normal range, and the threshold value calculation unit performs accuracy determination to determine the accuracy of the predictive determination based on the results of the predictive determination regarding the state values stored in the storage unit, and adjusts the calculation reference based on the result of accuracy determination.

A monitoring system is disclosed. The monitoring system comprises: a nozzle steam trap (3) including a supply portion (10) into which water vapor is supplied, and a discharge portion (11) which discharges liquid water contained in the water vapor; a temperature measurer (20) that measures a temperature of the discharge portion; a transmitter (24) that transmits temperature information containing the temperature measured by the temperature measurer; a receiver (7) that receives the temperature information; a determiner (8) that determines whether an abnormality is present in the nozzle steam trap based on the temperature information; and a notifier (9) that issues a notice when the determiner determines that the abnormality is present. A first discharge-side reference temperature lower than the boiling point of the water and a second discharge-side reference temperature higher than the boiling point of the water are set for the discharge portion. The determiner determines that the abnormality is present when the temperature of the discharge portion contained in the temperature information is lower than the first discharge-side reference temperature or higher than the second discharge-side reference temperature.

Devices, systems, and techniques relating to steam trap monitoring are described. These include battery-less steam trap monitors that run on power harvested from their environments, systems for acquiring steam trap monitor data for the traps in a facility or across multiple facilities, and techniques for processing steam trap monitor data to reliably determine the status of individual steam traps and potentially other system parameters.

A self-contained electronic steam trap drains condensate from a steam system. The steam trap includes a drain pipe adapted for fluid communication with a steam supply system. Pressure and temperature sensors measure pressure and temperature in an internal passageway of the steam trap. A condensate discharge valve is disposed at or upstream of an output port of the drain pipe. The condensate discharge valve is controlled based on the measured pressure and temperature and a calculated steam saturation temperature. Both a cycling mode and a regulation mode of automatic valve operation are described.
