THE WAYS TO IMPROVE THE MEASUREMENT SYSTEMS ON AN EXAMPLE OF THE SERVO SYSTEM OF DETERMINING THE DENSITY AND TEMPERATURE IN THE PIPELINE
(pp. 49-52)

Abstract. The problem of determination of oil certain parameters, specifically, density and temperature by means of measurement system are considered in this article. Theoretical review of measurement instruments and short analysis of method with greater measurement accuracy and volume of information are given. It is proposed the equation for information estimation of different modulation types: time, frequency, amplitude and pulse-code. Based on these equations, it is concluded that frequency modulation is preferable then amplitude and time. The balance between power interchange and receiving information is reviewed. The short description of pulse-code systems is presented. There are given the scheme of the measuring system for determining the density and temperature of the oil in the pipeline and also its description. The conclusions about advantages of continuous servo systems are drawn.

Keywords: measurement instruments, information energy, modulation, sensibility, accuracy, fast response, information, servo system.
