1 TECHNICAL DESCRIPTION
1.1 PURPOSE
SHVE, SGVE meters (fig. 1) are designed to measurement of drinking flowing through the pipeline
water volume according to
СанПиН 2.1.4.1074
-2001 with the temperature from 0,1 to 30 °
С
for cold water
meters (SHVE) and from 0,1 to 90 °
С
for hot water meters (SGVE with a pressure of water in pipeline no
more than 1.0 MPa (10kg/sm) and further collection and transmitting of this data to LoRaWAN network via
radio frequency band 860-1000 MHz.
SGVE meters are multipurpose and may be used as for measurement of cold as hot water volume,
but SHVE meters are only for cold water.

1.2 FUNCTIONS
Meters support the next functions:
•
displaying the counted water consumption in cubic meters via the LED indicator;
•
fixation of external magnetic field influence (electronic magnetic seal);
•
control of internal battery charge;
•
control of temperature inside device case (reference Information);
•
registration of random reverse flow of water (displaying the counted water modulo consumption in
forward and the reverse direction via the LED indicator);
•
leak fixation (continuous consumption < 0.3 cubic meter per 30 minutes);
•
fixation of a breakthrough (continuous consumption > 0.3 cubic meter per 30 minutes);
•
binding an emergency situation to the date and time and its saving;
•
testing in the manufacture and changing the parameters of the meter during operation through the
optical port;
•
pre-configured schedule for transmitting the collected data in the LoRaWAN network via radio
communication (choice the communication period);
•
pre-configured schedule for the data collection and saving in the internal memory (choice the data
collection period);
•
emergency transmitting of the collected data (extraordinary session);
