Abstract

The development of automatic pneumometric densitometers is promising not only for drilling fluids. They can be used in the food, chemical, refining, oil depots and storage facilities. Based on them, you can build systems for quantitative accounting of liquid products in units of mass. Possessing high accuracy, pneumometric densitometers are simple and reliable, convenient in operation and, most importantly, are completed with the elements serially issued by the industry.

The article presents a block diagram of a differential pneumometric densitometer with ballast pressure compensator in the minus pneumoline and shows the calculation which shows that the main source of error is the pressure loss in the pneumolines, zero drift of the differential pressure gauge, cancellation of real values ​​of static coefficients from differential. It is pointed out that in order to find the value of pressure and flow at each point of the pneumoline, even for simple models, it is necessary to make complex calculations. An analytical solution can only be obtained for individual cases that are of no practical value.

Therefore, for the analysis of a pneumoline of a densitometer it is most rational to use a method of electrohydraulic analogy (EGDA) and to pass from a pneumatic line with the distributed parameters to similar electric with rarefied parameters. We obtained a model of a pneumometric densitometer in the form of an electrical circuit, which requires further research, electrical engineering methods, to clarify the coefficients and parameters of the model and check its adequacy.
