MATERIAL AND METHODS.
As it is known that the enterprise uses a variety of
methods to control the production process, the quality of precast products and services. For
instance, experience, organoleptic, statistical, expert, etc. In the analysis and preparation of this
article, the methods of statistical analysis were widely used to cover the issues of metrological
support of production, industrial and scientific laboratories performing metrological work.
Indeed, in the process of manufacturing, defects caused by deficiencies in testing and scientific
laboratories and measurements, and the role of metrological support in overcoming these
deficiencies and shortcomings was shown.
The need for long-term mechanisms is also related to the creation of tools, including
intellectual tools, which must work for many years without human intervention. The task of
ensuring the metrological supply, i.e. the working condition of measuring instruments, remains
relevant.

However, with long-term operation of sensors (detectors), the role of influencing factors
increases, their consequences accumulate (spiritual deterioration of materials, increased
external influences, changes in magnetic properties, etc.), and the risk of metrological failure
increases.
Automation of control of equipment, especially in transport, as well as in energy-
intensive and hazardous areas, increases the importance of metrological failure and,
accordingly, the requirements for the reliability of measurement data.
According to Chinese experts, up to 60% of industrial failures and accidents are caused
by defects in the sensors. To minimize equipment obsolescence and reduce the risk of defects
and accidents, the metrological serviceability of measuring instruments should be checked
frequently and equipment performance should be increased — as infrequently as possible.
This requires monitoring the supply of laboratories of organizations engaged in
metrological supply, scientific, production and industrial enterprises and providing them with
the necessary measuring instruments.
However, here, also, some issues will arise if the device advertised by the supplier for
each of the metrologists purchased for the laboratory could not effectively solve the purchased
tasks, and negative results will occur with the purchase of a measuring instrument. Indeed, the
resulting measuring tool may not be fully compatible with the required functions. This gives a
great responsibility to the professionals in the following sphere. Currently, while buying some
equipment, enterprises pay a lot of money for additional options that never meet the demand.
Often, newly purchased devices will have difficulties in arranging to provide the required
environment on a regular basis.
Experience shows that most of these problems are explained by the fact that the task is
not clearly formed at the stage of decision-making on the purchase of a new measuring
instrument, complete information on all methods of solving it is not gathered and detailed
technical task is not prepared.
This problem is primarily due to the lack of knowledge necessary to make decisions
among professionals in enterprises. Today, most of the measuring equipment in the laboratories
of many enterprises has a service data of more than 25 years, and most metrologists do not have
enough knowledge about advanced measurement methods and the real capabilities of modern
devices. This situation is mainly used by manufacturers and suppliers of measuring
instruments, which provide information about the equipment supplied for advertising purposes,
often mentioning the limitations in the capabilities of the equipment they sell. It is difficult to
see the real features of the device in large advertising boards. Often, a supplier in a beautiful
package will offer outdated equipment “as a last resort”. If one has no knowledge of the new
tools and equipment he sees for the first time, it is almost impossible to evaluate all the
capabilities of the measuring tool, its performance characteristics; moreover, it is difficult to
assess how effective it will be. Therefore, it is necessary to act in accordance with the saying
“Better to see something once, than to hear about it a thousand times”. Metrologists try to get
information about such devices from their colleagues or try to see samples of the devices at
exhibitions and supplier conferences. This is the right approach, but it should be considered that
one’s measurement tasks and the opinions of his colleagues may not always be the same, the
operator working on this device may not be qualified enough, the operating conditions may be
incorrect and finally the new device may not have analogues in Uzbekistan.
However, the use of several types of sensors in the components of equipment and
measuring instruments produced in recent years, the use of software-based, imposes great
responsibilities on metrologists. Accordingly, the evolution of measuring instruments should be
more complex structure; and elements of artificial intelligence and metrological self-control
should have been introduced. Metrological self-monitoring is an additional procedure of
metrological support that reduces the risk of undiagnosed metrological failure and the
consequences of this failure. Under certain conditions, self-monitoring allows the evaluation of
the resulting error and the appropriate corrections to the measurement result. As shown, in
