Abstract

A steam trap may include a processor and an electronic water sensor configured to determine a presence of water in the steam trap and transmit data regarding the presence of the water to the processor. The steam trap may further include an electronically actuatable valve configured to be driven by signals from the processor.

Claims (31)

1. A steam trap comprising:

a processor;

an electronic water sensor configured to determine a presence of water in the steam trap and communicate data regarding the presence of the water to the processor;

an electronically actuatable valve configured to be driven by signals from the processor; and

at least one pressure sensor configured to measure pressure inside the steam trap and communicate pressure data to the processor;

wherein the processor is configured to transmit telemetry data to a centralized information handling system, the telemetry data including the pressure data; and

wherein the centralized information handling system is configured to determine a flow rate of condensate based at least in part on the telemetry data.

2. The steam trap of claim 1 , wherein the electronic water sensor is a sensor selected from the group consisting of capacitive sensors, optical sensors, acoustic sensors conductive sensors, and any combination thereof.

3. The steam trap of claim 1 , wherein the telemetry data further includes acoustic and/or vibrational signals, and wherein the processor is configured to perform a discrete cosine transform (DCT) on at least a portion of the telemetry data prior to transmission to the centralized information handling system.

4. The steam trap of claim 1 , wherein the transmission comprises wireless transmission.

5. The steam trap of claim 1 , wherein the telemetry data further includes physical parameters measured by the electronic water sensor.

6. The steam trap of claim 1 , wherein the electronically actuatable valve comprises a solenoid.

7. The steam trap of claim 1 , wherein the electronically actuatable valve comprises a valve sensor configured to measure a degree of openness of the electronically actuatable valve.

8. The steam trap of claim 7 , wherein the valve sensor is configured to transmit a signal to the processor indicative of the degree of openness of the electronically actuatable valve.

9. The steam trap of claim 8 , wherein the processor is configured to perform closed-loop control of the electronically actuatable valve based on the signal indicative of the degree of openness.

10. The steam trap of claim 1 , wherein the flow rate of the condensate is further determined based on data regarding an external pressure outside the steam trap.

11. The steam trap of claim 10 , wherein the data regarding the external pressure is measured by a second pressure sensor outside the steam trap.

12. The steam trap of claim 10 , wherein the flow rate of the condensate is further determined based on flow characteristics of a discharge fitting of the steam trap.

13. A steam system comprising:

a centralized information handling system; and

a plurality of steam traps, wherein each respective steam trap includes:

a processor;

an electronic water sensor configured to determine a presence of water in the steam trap and communicate data regarding the presence of the water to the processor;

an electronically actuatable valve configured to be driven by signals from the processor;

at least one pressure sensor configured to measure pressure inside the steam trap and communicate pressure data to the processor; and

a network interface;

wherein the processor is configured to transmit, via the network interface, telemetry data to the centralized information handling system, the telemetry data including the pressure data; and

wherein the centralized information handling system is configured to determine a flow rate of condensate based at least in part on the telemetry data.

14. The steam system of claim 13 , wherein each electronic water sensor is a sensor selected from the group consisting of capacitive sensors, optical sensors, acoustic sensors conductive sensors, and any combination thereof.

15. The steam system of claim 13 , wherein the telemetry data further includes acoustic and/or vibrational signals, and wherein the processor is configured to perform a discrete cosine transform (DCT) on at least a portion of the telemetry data prior to transmission to the centralized information handling system.

16. The steam system of claim 13 , wherein the transmission comprises wireless transmission.
