Accreditation
The NATA accredited Calibration laboratory offers a liquid flow meter calibration service. The laboratory uses multiple test benches and reference flow meters to maintain high accuracy over the entire flow range covered under the scope of accreditation. Low uncertainty levels are maintained for all flow rates between 4 L/h and 360 kL/h. The largest testing can accommodate flow meters of size up to DN300.
