SVTU-11T ultrasonic heat meter

FOR OF HEAT MEASURING ON APARTMENT HOUSES AND OTHER BUILDINGS WITH HORIZONTAL TYPE OF HEATING WIRING.

Devices measure volume, mass, excessive pressure of water or liquids with solids (not more than 200 mkm).

  • Accuracy degree – class 1, 2 (depends on performance);
  • Case material – stainless steel, steel 20;
  • Connection – flange;
  • DN – 20 mm – 400 mm;
  • Powering – battery (3.6 V);
  • Service life – not less than 12 years;
  • Warranty – 4 years.

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. 

SVTU-11 Т has a range of features:

  • Flow meter section made of stainless steel;
  • Flow sensors made of titan (excludes pollution and accuracy reducing);
  • There is possibility to produce flow node and temperature sensors for flooded places;
  • Various packets performance for flow sensors tie-in with pressure to 16 atm;
  • Standard package includes flanges (or clumping nuts), paronite gasket, fixing. For DN to 40 mm – straight sections (after 40 mm – by request);
  • Device can provide flow measurement few times per second for accuracy increasing;
  • Maximum cable length from computer to SVTU-11 Т sensors – 30 m. Maximum cable length to PC – 50 m. It allows to put out the computer from heat point to other place for comfortable working;
  • We supply devices for Ukraine utilities and abroad.
