Abstract

A flow sensing ozone converter includes an inlet housing, an outlet housing, and a central housing. The inlet housing defines a first pressure port. The outlet housing defines a second pressure port. The central housing extends between a second end of the inlet housing and a first end of the outlet housing.

First claim

What is claimed is:

1. A flow sensing ozone converter, comprising:
an inlet housing having an inlet housing first end, an inlet having a constant diameter extending from the inlet housing first end, and an inlet housing second end, the inlet housing defining a first pressure port and varying in diameter between the inlet housing first end and the inlet housing second end;
an outlet housing having an outlet housing first end, an outlet housing second end, and an outlet extending from the outlet housing second end, the outlet housing defining a second pressure port; and
a central housing extending between the inlet housing second end and the outlet housing first end.

2. The flow sensing ozone converter of claim 1 , wherein the at least one of the inlet and the outlet defines a port that is configured to receive a temperature sensor.

3. The flow sensing ozone converter of claim 1 , wherein the inlet housing further defines a third pressure port that is spaced apart from the first pressure port.

4. The flow sensing ozone converter of claim 3 , further comprising a first pressure sensor that is operatively connected to the first pressure port and the second pressure port.

5. The flow sensing ozone converter of claim 4 , further comprising a heat shield disposed between the first pressure sensor and the central housing.

6. The flow sensing ozone converter of claim 5 , wherein the heat shield is operatively connected to at least one of the inlet housing, the outlet housing, and the central housing.

7. The flow sensing ozone converter of claim 5 , further comprising a second pressure sensor that is operatively connected to the third pressure port.

8. The flow sensing ozone converter of claim 7 , wherein the inlet housing has a cross-sectional diameter that increases in a direction that extends from the inlet housing first end to the inlet housing second end.

9. The flow sensing ozone converter of claim 7 , wherein the outlet housing has a cross-section diameter that decreases in a direction that extends from the outlet housing first end to the outlet housing second end.

10. The environment control system as recited in claim 1 , further comprising a first piezometer ring disposed about the first pressure port, wherein the first piezometer ring having a diameter greater than that of the first pressure port.

11. The environment control system as recited in claim 1 , further comprising a second piezometer ring disposed about the second pressure port, wherein the second piezometer ring having a diameter greater than that of the second pressure port.

12. An environmental control system, comprising:
a flow sensing ozone converter comprising:
an inlet housing having an inlet housing first end and an inlet housing second end, the inlet housing defining a first pressure port disposed proximate the inlet housing first end and defining a first mounting feature disposed proximate the inlet housing second end, the inlet housing varying in diameter between the inlet housing first end and the inlet housing second end;
an outlet housing having an outlet housing first end and an outlet housing second end, the outlet housing defining a second pressure port disposed proximate the outlet housing second end and defining a second mounting feature disposed proximate the outlet housing first end, the outlet housing varying in diameter between the outlet housing first end and the outlet housing second end; and
a central housing extending between the inlet housing second end and the outlet housing first end.

13. The environmental control system of claim 12 , wherein the flow sensing ozone converter further comprises a heat shield that is operatively connected to the first mounting feature and the second mounting feature.

14. The environmental control system of claim 13 , further comprising:
a mounting bracket disposed on the heat shield.

15. The environmental control system of claim 14 , further comprising:
a first pressure sensor disposed on the mounting bracket and is operatively connected to the first pressure port and the second pressure port.

16. The environmental control system of claim 15 , wherein an outlet of the outlet housing defines a temperature sensor port that is disposed proximate the outlet housing second end.

17. The environmental control system of claim 16 , further comprising:
a temperature sensor operatively connected to the temperature sensor port.

18. The environmental control system of claim 17 , wherein the inlet housing defines a third pressure port that is spaced apart from the first pressure port.

19. The environmental control system of claim 18 , further comprising:
a second pressure sensor disposed on the mounting bracket and is operatively connected to the third pressure port.

20. The environmental control system of claim 19 , wherein the inlet housing and the outlet housing are integrally formed with the central housing.

21. The environmental control system of claim 19 , wherein the first pressure sensor is a differential pressure sensor.

22. The environmental control system of claim 19 , wherein the second pressure sensor is a static pressure sensor.
