4.1.2. Results of experimental researches
In Drawing 4.1 the schedule of values of a gauge pressure in UZR during tests is resulted. From it follows, that process of the fluxion of air of the elastic basin can be divided into 3 stages. At the first stage pressure sweepingly drops, as the elastic basin before installation of a plate with cargoes was pumped with small excess.
At the second stage pressure decreases very slowly (approximately on 5 Pases in a minute) and its stability allows to spend the verification works. At the third stage pressure in the basin again sweepingly drops, as during this moment the plate with a cargo attains the terminator and is shut down. In Drawing 4.2 the schedule of values of the charge of air during tests is resulted. It is analogous to the schedule in Drawing 4.1, and on it the same stages are tracked.

From Drawing 4.1 follows, that the first stage is manifested in that case when the basin is pumped much (for example, in the second cycle of measurements this
The section is absent). Hence, if at pumping to control a gauge pressure presence of an initial section can be avoided. The working section can be prolonged if to stow the cargo not on a plate, and suspending it in a special cradle, as is shown in Drawing 3.1. In this case the plate distortion at a small stock of air in the basin can be avoided.

For definition of magnitude of instability of the charge speed of change of the charge has been counted. It has appeared, that on a working section of the characteristic speed of change of the charge of air changes no more than on 0,5 % of/minute Considering, that pressure is measured every second and, accordingly, each 2 seconds calculation of the current charge is made, 15-30 seconds are quite enough precisely to count the average charge in each point of checking. Even at the maximum charge the linear section lasts not less than 15 minutes, at smaller charges, it is essentially extended. At checking of usual household counters of gas 4 points of a scale [17] are controlled. At automation of all procedure on the control of one counter it is required no more than several minutes. It will allow even with the basin of the same volume that was used in
The experimental sample rashodometricheskogo a complex, for one cycle of pumping of the basin to spend checking not less than ten counters [102].
Thus, use of the elastic basin in the capacity of ustrojstyova storage and pressure maintenance of the outlayed medium is quite admissible, as it provides high stability of pressure that is especially important for poyoverki the counters which are not creating at work own considerable pulsations of pressure.
The elastic basin favourably differs from bell mernika proyostotoj uses, absence of difficult system of suspension of a bell and a counterweight. Besides there is no necessity for the basin with water and the systems of maintenance of a fixed level of water connected with it, there is necessity periodiyocheskoj no water replacement in the basin. Besides the volume of the elastic basin can surpass volume bell mernika more in 10 times (comparing with SY85), that considerably expands dynamic range IRK.
Applied in existing IRU devices with the rigid basin (receiver) and an automatic control system of air pumping not obesyopechivajut the same level of stabilisation of pressure in comparison with the loaded elastic basin and considerably surpass the elastic basin in cost and power consumption.
