    The meters are designed to measure the volume of natural gas according to GOST 5542-87 and liquefied petroleum gas vapor according to DSTU EN 437-2014 when conducting gas metering, including commercial gas in the housing and utilities sector. The results of measuring the volume of gas and its temperature are displayed on a digital display. Gas meters do not need additional mounting systems. The stability of the metrological characteristics of EGL meters and resistance to climatic factors are confirmed by the results of operating household meters on natural gas in real conditions.

     EGL meters provide for the possibility of connecting the communication module by radio channels, which allows them to work as part of an automated data collection system:

A comprehensive solution
was developed to create an automatic data collection system from gas metering stations (hereinafter ADCS), designed to provide access to gas metering stations, as well as to form and compile balance reports by gas calculation and supervision services.

ADCS provides data transmission from gas metering stations by a wireless network to an enterprise server in order to compile balance sheets of gas consumers, conduct accounting and settlement operations, as well as for subsequent analysis of the data, identifying abnormal situations, compiling an individual profile of gas consumption for a group of enterprises and each subscriber, and their statistical monitoring.

The introduction of ADCS from gas metering stations allows you to:

— promptly receive information about the current gas consumption of each subscriber;
— automate the process of organizing gas metering and drawing up a balance;
— to simplify access to gas metering station indications, drastically reduce the influence of the human factor;
— timely detect attempts of unauthorized interference with gas metering stations;
— reduce the cost of servicing gas consumers;
— predict peak loads;
— reduce the loss of gas supplying companies due to increased culture and organization of accounting.

PURPOSE

Application at accounting units on which ECD gas meters are installed, in order to automate accounting, organization of information networks and provision of accounting data to the services of calculation and supervision, in accordance with the applicable accounting rules. Work with counters, which have a low-frequency output of the type “dry contact” with frequency up to 2 Hz and a pulse length of not less than 50 ms (LF); Reading information from the meter pulse counter.

ADVANTAGES

Package with a pulse counter EPL.
Remote change of the current and contract time of the radio module.
Remotely reading of archival and current BSG data upon request.
Built-in antenna.

FUNCTIONS

Receive pulse signals from the pulse sensor counter
Summing up the volume of natural gas in working conditions, according to
received data;
Accumulation and storage of archives of the obtained values of the volume of gas:
daily – within 112 days;
monthly – within 15 months;
Registration of magnet impact attempts;
Transmission of status, charge level and battery signal levels
radio module on the server dispatching.
Control of emergency situations of the meter.
Control of the intensity of the magnetic field of the pulse meter.
Wireless transmission of data through LORA modem with
EPL pulse counter for MSC-LORA concentrator and further
transferring these data to the dispatch server.
Wireless data reception with LORA-modem from
concentrator MSC-LORA and transfer of received information to
pulse meter EPL radio modules (requests for reading archives,
correction of time, reset of emergency situations, etc.).

continuous work for 8 years or more with the poll more often as 4 times a day.
Mode of operation – continuous uniterrupted.
The connection with the concentrator MSC-LORA is supported by distance
more than 500 m in conditions of dense urban development or no more than 3000 m in
conditions of private sector development.

    It provides:
 
  • ⦁ remote control and removal of information from the meter;
  • ⦁ automatic control of possible gas leakage; 
  • ⦁ prompt notification of unauthorized interventions in the meter operation. 
  • ⦁ the presence of an electronic module allows you to adjust the metrological characteristics of the meter, i.e. to make accounting of the consumed gas with the minimum error;
  • ⦁ protection against unauthorized interference with the meter operation, incl. exposure to a magnetic field;
  • ⦁ storage of measurement results in non-volatile memory;
  • ⦁ maintaining the stability of the metrological characteristics during the entire service life;
  • ⦁ only EGL household meters operate at a maximum pressure of 300 kPa;
  • ⦁ increased level of safety of operation of meters at ambient temperature up to 70 ° С, which allows installing the meter in close proximity to the gas stove in rooms with a small useful area of kitchens;
  • ⦁ modern design, small dimensions provide comfort of operation and maintenance, as well as ease of installation (15-20 minutes without using welding);
  • ⦁ meters are supplied complete with a highly efficient filter sump, which prolongs the life of the meter, and the use of flexible hoses during installation prevents the occurrence of mechanical stresses in the meter body, which is an additional plus in the measurement accuracy.
