test procedures

The calibration is based upon the “weighing method” according to standard ISO 4185. The flow is supplied by a constant head reservoir (at a height of 24 m). During a specified period water is collected in one of the weighing tanks, which mass is measured with calibrated load cells. From the mass increase, filling time and water density, the volumetric flow rate is determined. Tests are performed over the full operating range of the flow meter.
