Abstract

Intravenous Administration Set (IV Set) is one of medical devices that have been generally used in hospitals. Then, the primary standard calibration system appeared in this paper was set according to the IEC60601-2-24. The flow rate, volume and mass of distilled water which flowing through different IV sets are measured by using 1 mg resolution weighing balance, photoelectric sensors and data acquisition system. This is paper presents drop volume estimation compared with three different methods; surface tension calculation, drop counted by photoelectric sensor and gravimetric method. The results show comparison of the drop volume with the three different methods and error less than 5% for each IV set type. The uncertainty of measurement is 0.752% of reading (<i>k</i> = 2).
