KTM Deltapascal ®

Cost reduction projects for power consumption and pumping equipment service life. Metering of steam, hot liquids and ultrahot smoke emissions

Benefits:

  • Saving 5-15% on energy costs at the replacement of constriction devices with a Pitot tube due to pressure drop decrease from 20-30 % to 5-8 %;
  • Increase of the steam turbine or pump service life and equipment life of 20% due to incoming pressure reduction;
  • Reduction of expenses by 4 times for the flow meter assembly/disassembly, calibration, shipping costs, exchange fleet, no repair expenses;
  • Integrated computing device in explosion-proof housing, ready for volume calculations without additional equipment;
  • In-process assembly/disassembly;
  • Simulation calibration;
  • Temperature and pressure flow compensation;
  • Metering on exhaust ducts of complex shape;
  • Metering of high temperature gases to +710 °С to 25 MPa;
  • Metering of air emissions on pipelines with diameters to 15 m;
  • Calibration interval – 4 years, service life – 18 years.
