Measuring Instruments
Portable ultrasonic
Ultrasonic methods are an integral part of most instrumentation measuring instruments, especially non-contact devices. In ultrasonic flow meters that are used in a wide range of gaseous and liquid fluids, the Doppler properties are familiar with physics. Frequency of a source. On the other hand, a receiver checks this frequency instantaneously. If the flux of fluid changes, this switching frequency will change significantly due to the speed of the fluid. Measuring and calibrating these changes in terms of flowing will allow you to measure flux in an ultrasonic way. In practice, the technique of measuring flux in an ultrasonic way will have its own complexity, but the basis of measuring most of the ultrasonic flowmeters is the Doppler mechanism.
In the selection of ultrasonic flowmeters, consider the following:
Flow Measurement Range
Line pressure
installation method
Density or fluid viscosity
Portable or fixed device
The presence of particles in the fluid
