Desription

The device accounts, displays and saves temperature, volume and mass of water. Saving provides in archives (hourly, daily, monthly, yearly). Ultrasonic waves emit in the flow direction and against. Based on time difference volume of water flow calculates.

Included in the delivery package:

Flow meters - DN15-100. There are made from brass or stainless steel with anti-corrosion coating. There is IP-68 protection degree. - 2-piece;
Flow meters DN32 – 40 (equipped with straight sections);
Flow sensors – 2-piece. For two-channel – 4-piece4
Temperature sensors (equipped with protection sleeves) – 1-piece, if device is used to account hot water;
Cables from electronic block to TS-1.15, 2, 3-20 m, 1 m increments, or to another flow measuring section;
The heat meters are identical by overall dimensions to modern European manufacturers. It makes possible to replace water meters without usage of straight sections;
SVTU-11 RP electronic block. Case made of plastic. Protection degree – IP-65. – 1-piece;
Water meters have a 4-tariff accumulator which is possible to print data for chosen tariff.
