| description | Background. In commercial accounting, the task of accurately measuring the
level of liquid and bulk materials stored and transported in tanks is very relevant.
The aim of this work is to analyze ways to reduce the influence of the parameters of
the ultrasound propagation medium on the measurement accuracy of echolocation
level gauges and develop recommendations for improving the proposed method and
device for level measurement.
Materials and methods. Experimental and theoretical studies of the method and
microprocessor-based device previously proposed by the authors for measuring the
level of separation of media in tanks showed the presence of a methodological error
determined by the radial propagation of an ultrasonic wave in a gaseous medium
when reflected from the boundaries of separation of media and elements of the tank
structure. Analysis of the propagation path of reflected and re-reflected ultrasonic
waves in a tank of a given design showed the presence of a methodological error,
which can be eliminated by introducing a digital correction in the measurement result.
Results. The well-known methods of increasing the accuracy of ultrasonic level
meters are considered. A microprocessor-based implementation of the level meter is
proposed, which differs in the independence of the propagation velocity of an ultrasonic
wave from the parameters of the gas medium of the reservoir, which provides
high metrological characteristics with a relatively simple hardware implementation.
This allows the developed level gauge to be used in the custody transfer of various
liquid and bulk materials in tanks.
Conclusions. The introduction of a digital correction into the measurement result,
taking into account the design parameters of the tank and the radial propagation
of an ultrasonic wave when reflected from the surfaces of the controlled substance
and the elements of the tank structure, provides high metrological and operational
characteristics of the developed microprocessor level gauge. |
