Hydrostatic levels
The levels operate on the basis of the principle of communicating vessels.
Hydraulic engineering structures:
The levels can be used at hydroelectric power plant facilities and on earth dams.
Hydraulic engineering structures:
The levels can be used at hydroelectric power plant facilities and on earth dams.
The instruments are installed on ground reference marks. The automation of earth dam deformity monitoring minimizes the risk of formation of circular cylindrical slip surfaces (in case of suffusion or seismic activity).
The hydrostatic levels can be easily fitted in footways, turbine halls and galleries to provide comprehensive information about general deformities and, thus, to minimize the risk of accidents and to prolong service life of the monitored structures.

State-of-the-Art Automated
Alarm System
Should any slightest deviation from normal parameters be detected, the system will immediately generate and send e-mails and SMS to all persons in charge (the engineer will get the first alarm message when 60% of the threshold is reached; and his senior will get such message at 80% of the threshold).
Readings of the hydrostatic levels, which may be of any concern, are always available to authorized specialists for analysis on company’s internal or external servers.
Permanent
mathematical model
Stress is related to strains, and such relationship is fundamental.

Volumes of data on starins, which is collected by the hydrostatic levels, are large and, therefore, such data can be used in computational modeling of structure status. All computations performed can be used and reused to compare them to actual readings. At the same time, every computed model provides for further automated computations, which will always be accurate.




Thus, we will be able to forecast areas of brittle and plastic fracture and to timely take all measures required to minimize the risk of possible accidents and to reduce maintenance costs.
Scope of Use
of “Monitron” Hydrostatic Levels
Construction
of Underground Facilities

Pit excavation, tunneling and construction of other underground facilities result in settling of surrounding soil masses. Such deformation processes may cause fracturing of structures within the area of such works.

The hydrostatic levels promptly detect any drifting and, thus, provide for adjustment of construction processes or development of compensating measures, as appropriate.

The levels minimize the following risks intrinsic to construction of underground facilities:
  • 1. Changes in characteristics of accommodating soil masses, which may be caused by:
    • a) Suffusion and karst processes in foundations;
    • b) Soil loosening caused by washing out of soil into tunnels in case of local leaks and loss of sealing; and
    • c) Development of any other dangerous engineering and geological processes and phenomena (including landslides, barrage effects, and creeping);
  • 2. Service wear in the form of corrosion of reinforcing bars and concrete lining fractures;

  • 3. Human factors, including:
    • a) Car crashes, and rail accidents;
    • b) Excavations and construction operations in violation of applicable procedures;
    • c) Poor quality of design and engineering drawings and documentation; and
    • d) Any other factors causing impairment of strain and strength characteristics of load-bearing frames or changes in the state of soil.
Bridges
(Maintenance)

Timely fixing of abnormal sags of spans of some beams eliminates risks of crashing or abnormal operating conditions. Any such issues can be detected by comparison of current data to data for analogous structures.

Settling or misalignment of bridge piers will signalize issues with foundations or changes in mechanical parameters of bridge structures (including those caused by human factors, such as vehicles crashing into bridge structures).

Oil Terminals
(Maintenance and Construction)

Permafrost thawing may result in irregular settling of oil terminals, which significantly increases the risk of fracture of tanks. Deployment of hydrostatic levels will help you to avoid such dangers.

Repeated loading/unloading (tank filling/emptying) cycles may cause fatigue of metal structures and, therefore, may result in irregular settling of tanks.

Seismic Specifications
(Assessment of Effects of Seismic Activity)

Prompt assessment of structure drifting after seismic events will help emergency response teams to timely and effectively solve the issue of response priority.

Use of several circuits will facilitate assessment and help to discern the extent of fracture of foundation soil from that of structures. For instance, if the underground circuit shows no changes while the circuit above the ground does detect them, it means that the foundation soil remains intact but the structures are damaged.

Maintenance
of Underground Structures

Thanks to the adaptive mounting, “Monitron” hydrostatic levels can be positioned relative to two perpendicular axes (according to surface geometry of the place where they are installed) in most difficult conditions.

In the process of maintenance of underground structures, the hydrostatic levels provide for assessment of effects of dangerous engineering and geological processes and phenomena (such as suffusion processes, barrage effects, soil creep, and destruction of karst landforms).

About Our Company
“Monitron” LLC is a Russian company supplying automated systems for real-time monitoring of vertical movement of structures, which are based on digital hydrostatic levels manufactured by our Company.

“Monitron” LLC started developing hydrostatic levels in 2012. The following specialists of “Research and Engineering Center of the Tunnel Association” LLC were engaged in the process: V.E. Merkin, Prof., D.Eng., Research Manager; A.N. Simutin, PhD, Chief Project Engineer; and G.M. Medvedev, Project Manager.

Our products are manufactured at several major Russian production facilities with current output of up to 10 000 hydrostatic levels a month.

In 2016 our Company started testing and elaborating the system – the tests were carried out at dozens of high criticality rating facilities (view all projects).
