Evaluation procedures of ultrasonic signals in gas flow metering
In technical processes very often signals are generated which are complex modulated and superposed by stochastic disturbances or noise. A typical example is an ultrasonic wave passing a streaming fluid perpendicularly which is complex modulated by stochastically distributed turbulences. The signal can be demodulated digitally by undersampling to separate the narrow sidebands. The complex modula...
متن کاملUltrasonic Transducers for Gas and Liquid Flow Metering
Accurate fluid flow metering is essential for modern process control, and ultrasonic flow meters are well established in this area. However, the specific acoustic impedance mismatch for most piezoelectric ultrasonic transducers is different when operating liquids and gases, hence there are problems measuring two-phase flows when using a single type of piezoelectric transducer in a flow meter. T...
متن کاملModeling of particle flow due to ultrasonic drilling
In-situ sampling and analysis is one of the major tasks in future NASA exploration missions. It is essential that the samples acquired on other planets including Mars are free of contaminations from the earth. Recently, a novel drilling technology that is actuated by a piezoelectric drive mechanism was developed and it is called Ultrasonic/Sonic Driller/Corer (USDC). This drill has an inherent ...
متن کاملAn Enhanced Technique for Ultrasonic Flow Metering Featuring Very Low Jitter and Offset
This paper proposes a new, improved method for water flow metering. It applies to a transit time ultrasonic flow meter device. In principle, the flow of a given liquid in a pipe is obtained by measuring the transit times of an ultrasonic wave in the upstream and downstream directions. The difference between these times is, in theory, linearly proportional to the liquid flow velocity. However, t...
متن کاملTurbulent Pulsating Flow through Circular Ducts
In the present paper, a numerical method has been demonstrated which works on an overall NewtonRaphson type algorithm and is capable of solving the “inverse” problem for turbulent, fullydeveloped, pulsating pipe flows, where the mass flow rate, rather than the pressure gradient is prescribed as a periodic function of time. The momentum equation, governing the transient, fullydeveloped pulsating...
