Abstract

A flowmeter having an adjustable protective shield for calibrating the flowmeter is presented. The flowmeter includes an inner conduit providing a flow path for pressurized fluid, a protective shield having a plurality of markers providing a visible indicator of the flow rate of the pressurized fluid according to the position of the float in the flow path, and a housing assembly for receiving the inner conduit and the protective shield. The flowmeter also can include a fitting assembly for securely coupling the inner conduit, the flow label, and the housing assembly in-line within a pipeline path. The flowmeter can be calibrated by adjusting the position of the protective shield while in-line within the pipeline path.

First claim

What is claimed is:

1. A flowmeter comprising:
an inner conduit providing a flow path for pressurized fluid;
a protective shield having a plurality of markers providing a visible indicator of a flow rate of the pressurized fluid according to the position of a float in the flow path; and
a housing assembly for receiving the inner conduit and the protective shield;
wherein the flowmeter is calibrated by adjusting the position of the protective shield;
wherein the protective shield is an intermediate conduit for receiving the inner conduit.

2. The flowmeter of claim 1 wherein the housing assembly further comprises another protective shield for viewing the float and plurality of markers.

3. The flowmeter of claim 2 wherein the protective shield is made of polycarbonate.

4. The flowmeter of claim 1 wherein the inner conduit is made of borosilicate glass.

5. The flowmeter of claim 1 wherein the housing assembly includes a window for viewing the plurality of markers.

6. The flowmeter of claim 1 further comprising a fitting assembly for securely coupling the inner conduit, a flow label, and the housing assembly in-line within a pipeline path.

7. The flowmeter of claim 6 wherein the flowmeter is calibrated by adjusting the position of the protective shield while in-line within the pipeline path.

8. A flowmeter comprising:
a conduit providing a flow path for pressurized fluid;
a protective shield having a plurality of markers providing a visible indicator of the flow rate of the pressurized fluid; and
a housing assembly for receiving the inner conduit and the protective shield;
wherein the flowmeter is calibrated by adjusting the position of the protective shield;
wherein the protective shield is an intermediate conduit for receiving the inner conduit.

9. The flowmeter of claim 8 wherein the housing assembly further comprises another protective shield for viewing a float and plurality of markers.

10. The flowmeter of claim 9 wherein the protective shield is made of polycarbonate.

11. The flowmeter of claim 8 wherein the inner conduit is made of borosilicate glass.

12. The flowmeter of claim 8 wherein the housing assembly includes a window for viewing the plurality of markers.

13. The flowmeter of claim 8 further comprising a fitting assembly for securely coupling the inner conduit, a flow label, and the housing assembly in-line within a pipeline path.

14. The flowmeter of claim 13 wherein the flowmeter is calibrated by adjusting the position of the protective shield while in-line within the pipeline path.

15. A flowmeter comprising:
an inner conduit providing a flow path for pressurized fluid;
a protective shield having a plurality of markers providing a visible indicator of the flow rate of the pressurized fluid;
a housing assembly for receiving the inner conduit; and
a fitting assembly for securing the inner conduit and the housing assembly in-line within a pipeline path;
wherein the fitting assembly includes a reservoir fitting with a tap for draining the reservoir fitting of liquid received from the housing assembly;
wherein the flowmeter is calibrated by adjusting the position of the protective shield;
wherein the protective shield is an intermediate conduit for receiving the inner conduit.

16. The flowmeter of claim 15 wherein the tap is coupleable with a plug.

17. The flowmeter of claim 15 wherein the flowmeter can be calibrated by adjusting the position of the protective shield while in-line within the pipeline path.

18. The flowmeter of claim 15 wherein the protective shield is made of polycarbonate.
