High power 1MHz ultrasonic flow sensor for liquid flowrate
measurement
The need for accurate and reliable sensors is growing in so many
markets around the world, such as industrial and manufacturing,
automotive, medical, energy, and smart grid applications. The
designers and end-users of these sensors are counting on newer
technologies that use less power and deliver higher accuracy --
technologies that will eliminate moving parts and allow sensing in
remote locations and in less- than-ideal conditions. One of the
most effective areas of sensor technology is ultrasonic, the
science that measures the time interval between an ultrasonic
signal that is sent and received, or what is commonly referred to
as "time- of-flight" (TOF). TI is leveraging its ultrasonic
expertise to deliver new signal conditioning solutions to fluid
level sensing, fluid identification, flow metering, and distance
sensing customers with its latest product based on time-to-digital
converters .
