5 Conclusion

Ultrasonic sensing utilizing Time Of Flight (TOF) measurement techniques is used in liquid level and fluid identification sensing applications. In order to create a solution that is optimized for size, cost, and performance, one must first choose the right transducer for the application. Determining if the application can tolerate the transducer being mounted on the outside of the tank is the first start. Once this is known, a system designer can select a transducer with the appropriate package requirements and resonance frequency. With the transducer selected, the designer can now start to prepare the tank surface for proper transducer mounting. Having properly mounted the transducer, Texas Instruments TDC1000 can be connected to the transducer and application specific measurements can begin.

Texas Instruments offers a wide variety of tools in order to help a system designer create their ultrasonic sensing solution for liquid level sensing, liquid identification, and flow sensing using the TDC1000. Visit http://www.ti.com/ultrasonic for more details on the tools and collateral available.
