Mendoza Laboratory

Mass and volume flowmeter calibration

We have a new gravimetric test bench for the calibration of mass and volumetric flowmeters. The most modern in the southern cone, with a state-of-the-art speed variator for continuous control of the magnitude of the flow.

We integrate the National Laboratory Network of the SAC (Argentine Calibration and Measurement Service), supervised and audited by the INTI under ISO 17025. Official Laboratory N° 68.

Our experience in measurements, calibrations, metrology, laboratory management, design and construction of test benches, guarantee our work.

Our laboratory has a high-precision HBM electronic weighing system, of German origin that allows us to work with a resolution of 0.2 Kg involving 45,000 external accounts, which translates into an uncertainty of less than 60% of which, up to Now, they have the best test banks in the country.

  • 75HP pump that allows us to reach a maximum flow of 9000 liters / min.
  • Stainless piping with three sections for simultaneous installation of meters.
  • Latest generation controller, for the automatic realization of the calibration cycle, parameterized for different types of flow meters.
  • Patterns with traceability certified to INTI.
  • In addition, our certificates comply with the law as established in resolution 318/2010 of the Ministry of Energy of the Nation.
Neuquén Laboratory

Calibration for mass and volumetric meters by comparison


  • Capacity 5000 liters / min.
  • Flow control via speed variator.
  • 40 HP pump
  • Metrized Calibration Routine

Dry Calibration

Calibration of ultrasonic flowmeters for gas measurement. As in factory, we use high purity Nitrogen gas, pressure and temperature calibrated sensors, and apply a procedure to evaluate de performance of the meter and obtain a Zero Flow and sound of speed calibration.
