Cost effective 3-beam ultrasonic flowmeter for custody transfer of liquid hydrocarbons

  • Excellent long-term stability and high reliabilty
  • Eliminates maintenance
  • Non-intrusive, no moving parts; no pressure loss, no wear
  • Compliant with OIML R-117 and API

KROHNE’s ALTOSONIC III offers decisive advantage over conventional, mechanical flowmeters in custody transfer metering applications. The absence of obstructions in the pipe and moving parts results in no wear and no pressure loss.

The benefits this brings are maintenance free operation and simplified meter run configuration (smaller pump capacity, no filters required). This results in considerable cost savings in both capital expenditure (CAPEX) and operation expenditure (OPEX).
