Residential gas flow meter Energoflow HORN

Domestic Gas Meter HORN

Overview

Gas Meter HORN is designed to measure the volume of natural gas or degasified hydrocarbon gas for households and public utilities adjusting the measured gas volume, and displaying the amount of consumed gas on the meter indicator with the ability to transfer information to a centralized accounting system.

The meter is intended for continuous operation under the following conditions:
  • ambient temperature from minus 25 to 70°С;
  • humidity not more than 95 % at temperature not exceeding 35°С and lower temperatures without condensation;
  • atmospheric pressure from 84 to 106,7 kPa (from 630 to 800 mm Mercury);
  • the highest operating pressure not exceeding 50 kPa.
The meters are produced of four nominal sizes G1.6, G2.5, G4, G6 in three modifications:
1 / 0 – with optical port;
1 / 1 – with optical port and built-in wireless modem;
0 / 0 – without optical port and wireless modem.

The initial installation and initialization of HORN Gas Meters are performed using standard IR-DA port with a connection to the nearest concentrator in a network (within a radius of 500 meters). The approximate number of meters per one concentrator ranges from 200 to 300 units. The concentrators are powered by 220V, solar panels or battery backup. The concentrators transfer collected information to the online network by any available means including GPRS/GSM/3G/Ethernet.

Information is further received by the server in an encrypted form and decoded. Information garbling and hacking are impossible. The server receives instant notifications in case of emergency situations, deviations of the supply voltage or when trying to access files using the IR-DA port. 
The shut-off valve eliminates the risk of gas contamination (for stoves not equipped with gas control system) and helps to cut off gas supply in case the gas consumer has run out of credit. To resume gas supply, the person using the equipment must press a special button or complete the procedure in any other prescribed manner.

Installation configurations
System features enhance application of metering devices and control of gas consumption, and allow the following:
  • Monitoring the equipment condition;
  • Alerting - in cases of emergencies, control center gets corresponding messages;
  • Transferring meter readings.
  • Saving and sending event report indicating emergencies, dispatcher actions, alarm reporting, turning on/off the equipment.
  • Regular data backup on the server excluding information loss.
  • Generating flow rate balance information to detect losses, leakages and tampering.
  • Reducing man-made risks when dealing with gas equipment.
