Abstract
A vortex flowmeter measures process fluid flow. The vortex flowmeter includes a conduit that carries the process fluid. A sensing device is housed in a cavity of a sensor housing that is coupled to the conduit. A flexure is disposed in a portion of the conduit. The flexure is configured to isolate the process fluid in the conduit from the sensing device and is coupled to the sensing device. A hydrogen getter module is connected to the cavity and configured to remove hydrogen from the cavity to protect the sensing device.
Claims20
A vortex flowmeter for measuring process fluid flow comprising:
- a conduit for carrying process fluid;
- a sensing device housed in a cavity of a sensor housing coupled to the conduit;
- a flexure disposed in a portion of the conduit and coupled to the sensing device, the flexure configured to isolate the process fluid in the conduit from the sensing device;
- and
- a hydrogen getter module coupled through a passage to the cavity and configured to remove hydrogen to protect the sensing device housed in the cavity.
A vortex flowmeter for measuring process fluid flow comprising:
- a conduit for carrying a process fluid along a conduit axis, the conduit having an area of reduced thickness between exterior and interior surfaces of the conduit;
- a shedding bar disposed in the conduit and including a pivoting member that fluctuates in response to fluctuation in pressures;
- a sensing device housed in a cavity of a sensor housing coupled to the conduit, wherein the sensing device is isolated from the process fluid by the area of reduced thickness of the conduit;
- and
- a hydrogen getter module coupled through a passage to the cavity and configured to remove hydrogen from the cavity to protect the sensing device housed in the cavity.
