Description 851-863
Over the past decade, micro-liquid flow measurement has become increasingly important, particularly in India, where
devices like syringe pumps, infusion pumps, and infusion device analyzers are critical in hospitals and research laboratories.
These devices are essential for precise drug dosing in applications such as chemotherapy, pain management, insulin therapy,
and other vital treatments, making accurate calibration crucial. To meet this need, the Fluid Flow Metrology Section at the
CSIR-National Physical Laboratory (CSIR-NPL) in New Delhi has developed a state-of-the-art calibration facility for
micro-liquid flow, capable of measuring flow rates from 10 mL/h to 1500 mL/h. The facility employs a static weighing
method, utilizing a dual-range analytical balance with a capacity of 220 g/82 g and a digital timer as reference standards.
This setup achieves an expanded uncertainty of 0.30% (at k=2) for both totalized volume and volume flow rate
measurements, thereby ensuring the facility's status as a National Metrology Institute (NMI) in micro-liquid flow
measurement.
