Abstract

A flow sensing device includes a first body member defining an inlet port, an upstream sensor port, and a first connecting port; a second body member defining an outlet port, a downstream sensor port, and a second connecting port; a flow restricting element defining a flow restricting passage and including a first end connection coupled to the first connecting port and a second end connection coupled to the second connecting port, such that the flow restricting passage is disposed between the inlet port and the outlet port, and between the upstream sensor port and the downstream sensor port; a first fluid sensor assembled with the upstream sensor port; and a second fluid sensor assembled with the downstream sensor port.

First claim

We claim:

1. A flow sensing device comprising:
a first body member defining an inlet port, an upstream sensor port, and a first connecting port;
a second body member defining an outlet port, a downstream sensor port, and a second connecting port;
a flow restricting element defining a flow restricting passage and including a first end connection coupled to the first connecting port and a second end connection coupled to the second connecting port, such that the flow restricting passage is disposed between the inlet port and the outlet port, and between the upstream sensor port and the downstream sensor port;
a first fluid sensor assembled with the upstream sensor port; and
a second fluid sensor assembled with the downstream sensor port;
wherein the first and second end connections comprise zero clearance connectors that provide for removal and reinstallation of the flow restricting element with the first and second body members without movement of the first and second connecting ports, the zero clearance connectors each including a male threaded connector having an end face groove retaining an O-ring seal.

2. The flow sensing device of claim 1 , wherein the flow restricting passage is configured to provide laminar flow.

3. The flow sensing device of claim 1 , wherein the first and second end connections comprise O-ring face seal fittings.

4. The flow sensing device module of claim 1 , wherein the first and second connecting ports extend laterally from the first and second body members in a first direction, and the flow restricting element is substantially U-shaped.

5. The flow sensing device of claim 1 , wherein the flow restricting element comprises at least a first coupling member defining at least one of the first and second end connections.

6. The flow sensing device of claim 5 , wherein the flow restricting passage is integrally formed in the first coupling member.

7. The flow sensing device of claim 5 , wherein the flow restricting passage is defined by a flow restricting insert assembled with the first coupling member.

8. The flow sensing device of claim 7 , wherein the flow restricting insert is disposed in a through bore between the first and second end connections.

9. The flow sensing device of claim 7 , wherein the flow restricting insert comprises an apertured plate.

10. The flow sensing device of claim 7 , wherein the flow restricting insert comprises a threaded apertured insert installed in a female threaded portion of the first coupling member.

11. The flow sensing device of claim 7 , wherein the flow restricting insert is disposed in one of the first and second end connections.

12. The flow sensing device of claim 5 , further comprising a second coupling member joined with the first coupling member and defining the other of the first and second end connections.

13. The flow sensing device of claim 12 , wherein the flow restricting passage is defined by a flow restricting insert captured between the first and second coupling members.

14. A fluid monitoring module comprising:
a flow sensing device including:
a first T-shaped body member defining a laterally extending inlet end port, a laterally extending upstream sensor end port, and an axially extending first connecting end port;
a second T-shaped body member defining a laterally extending outlet end port, a laterally extending downstream sensor end port, and an axially extending second connecting end port;
a flow restricting element defining a flow restricting passage and including a first end connection coupled to the first connecting end port and a second end connection coupled to the second connecting end port, such that the flow restricting passage is disposed between the inlet end port and the outlet end port, and between the upstream sensor end port and the downstream sensor end port;
a first fluid sensor disposed within the upstream sensor end port; and
a second fluid sensor disposed within the downstream sensor end port; and

a controller in circuit communication with the first and second fluid sensors for receiving at least one of pressure indicating signals and temperature indicating signals from each of the first and second fluid sensors, and for measuring fluid data based on the received signals;
wherein the first and second end connections comprise zero clearance connectors that provide for removal and reinstallation of the flow restricting element with the first and second body members without repositioning the first and second connecting end ports.

15. The fluid monitoring module of claim 14 , further comprising a wireless transmitter for wirelessly communicating the fluid data from the controller to a remote device.

16. The fluid monitoring module of claim 14 , wherein the fluid data comprises at least one of fluid pressure, fluid temperature and fluid flow rate.

17. A fluid monitoring module comprising
an enclosure;
a fluid sensing device assembled with the enclosure, the fluid sensing device including:
a first body member defining a first end port, a first sensor port, and a first connecting port;
a second body member defining a second end port, a second sensor port, and a second connecting port;

a first fluid sensor assembled with the first sensor port; and
a second fluid sensor assembled with the second sensor port;
and
a controller disposed within the enclosure and in circuit communication with the first and second fluid sensors for receiving at least one of pressure indicating signals and temperature indicating signals from each of the first and second fluid sensors, and for measuring fluid data based on the received signals;
wherein the first and second sensor ports extend laterally inward through first and second mounting apertures in the enclosure, such that the first and second sensor ports are disposed within the enclosure and the first end port, the second end port, the first connecting port, and the second connecting port are external to the enclosure.

18. The fluid monitoring module of claim 17 , further comprising a flow restricting element defining a flow restricting passage and including a first end connection coupled to the first connecting port and a second end connection coupled to the second connecting port.
