Ultrasonic liquid flowmeter for custody transfer

ALTOSONIC 5 - Ultrasonic liquid flowmeter for custody transfer
  • Suitable for all flow regimes, no Reynolds limitation
  • Integrated gas detection
  • Significantly easier to be proved using small volume provers

The ALTOSONIC product line for fluids has established itself as the standard in multi-beam custody transfer flow metering. The absence of obstructing and moving parts ensures no wear or pressure loss. This in combination with large meter sizes permits simplified configuration of metering systems.

Operation is maintenance free. Due to long-term stability, periodic calibration can be reduced to a minimum which results in drastically cutting costs for on-site equipment and procedures.

In addition, the diagnostics of the flowmeter will ensure a good performance and will prevent malfunctioning of the measurement by providing essential information upon which the operator is able to take preventive action.

This all results in considerable cost savings in both capital (CAPEX) and operational expenditure (OPEX).
