Acoustically isolated ultrasonic transducer housing and flow meter
An ultrasonic transducer apparatus is provided. In one embodiment, the apparatus includes an outer housing, an inner housing disposed within the outer housing, and an ultrasonic transducer disposed within the inner housing. The outer housing has an aperture that enables pressurized fluid to enter the outer housing while allowing the outer housing to acoustically isolate the inner housing and the ultrasonic transducer from an additional component when the outer housing is connected to the additional component. Additional systems, devices, and methods are also disclosed.
1. An ultrasonic transducer apparatus comprising:
an outer housing;
an inner housing disposed within the outer housing; and
an ultrasonic transducer disposed within the inner housing;
wherein the outer housing includes an aperture that enables pressurized fluid to enter the outer housing while allowing the outer housing to acoustically isolate the inner housing and the ultrasonic transducer from an additional component when the outer housing is connected to the additional component.
2. The ultrasonic transducer apparatus of claim 1 , wherein the additional component is a plug coupled to a flow meter body.
3. The ultrasonic transducer apparatus of claim 2 , wherein the outer housing is threaded to the plug.
4. The ultrasonic transducer apparatus of claim 3 , wherein the inner housing and the plug are metal and the outer housing prevents metal-to-metal contact of the inner housing with the plug.
5. A method comprising:
inserting an ultrasonic transducer housing into a sleeve having a fluid port;
coupling the sleeve to a carrier; and
coupling the carrier to a flow meter body such that the ultrasonic transducer is positioned in space within a conduit of the flow meter body and the fluid port places an interior of the sleeve about the ultrasonic transducer housing in fluid communication with the conduit.
6. The method of claim 5 , wherein coupling the carrier to the flow meter body includes installing the carrier in a bushing and coupling the bushing to the flow meter body.
7. The method of claim 5 , wherein coupling the carrier to the flow meter body includes coupling the carrier to the flow meter body such that the ultrasonic transducer is positioned in-line with a direction in which a fluid would flow through the conduit when traveling between inlet and outlet ports of the flow meter body.
8. The method of claim 7 , comprising using the ultrasonic transducer to measure flow rate of the fluid routed through the conduit.
