Apparatus and methods for sensing fluid parameters
First Claim
1. An apparatus to facilitate using a sensor device in sensing at least one parameter of a fluid in a conduit, said apparatus comprises:
- a tap body having a first end region and a second end region and adapted to be secured to the wall of a conduit so that said first end region extends into said conduit and said second end region extends outside of said conduit;
said tap body defining a fluid flow passage which includes an inlet located in said first end region, an elongated inlet leg in fluid communication with said inlet, a sample zone at least partially in said second end region and in fluid communication with said inlet leg, an elongated outlet leg in fluid communication with said sample zone and an outlet located in said first end region and in fluid communication with said outlet leg, said inlet leg and said outlet leg being of differing lengths;
said tap body being further adapted to be secured to the sensor device effective in sensing at least one parameter of fluid in said sample zone; and
said tap body comprises a tap stem which includes said first end region, said inlet, said outlet, a portion of said inlet leg and a portion of said outlet leg; and
a flow cell body which includes a portion of said inlet leg, a portion of said outlet leg, said sample zone and said second end region.

Abstract
Apparatus to facilitate sensing a parameter of a fluid in a conduit include a tap body including a first end region and a second end region. The tap body is adapted to be secured to the wall of a conduit so that the first end region extends into the conduit and the second end region extends outside of the conduit. The tap body defines a fluid flow passage which includes an inlet located in the first end region, an inlet leg in fluid communication with the inlet, a sample zone at least partially in the second end region and in fluid communication with the inlet leg, an outlet leg in fluid communication with the sample zone and an outlet located in the first end region and in fluid communication with the outlet leg. The tap body is further adapted to be secured to a sensor device including a sensor effective in sensing at least one parameter of fluid in the sample zone. Methods for sensing a parameter of a fluid in a conduit are also provided.
