Abstract

A measure of liquid thickness is needed to make a dough or formula for medicinal syrup. The tools to measure the thickness available in the market are analog that is less accurate and precision. To overcome these problems, digital density measuring devices are needed. The limitation of the digital density meter, especially liquid, urges the author to carry out further research on the digitization of this measuring instrument. This research aims to make a digital density meter for liquid matter with a high level of measurement accuracy, as the reference measurement study for liquid density in digital form. The instrument was designed using the load cell method as the main sensor. It was also equipped with a DS18B20 water-resistant temperature sensor to measure the temperature of the liquid. The data were analyzed to obtain the accuracy and error of the liquid density measurement from the density meter. The liquid samples used for research were Pertamax, solar, and water. Sample accuracy and error measurement results were 99.83 percent and 0.17 percent respectively for Pertamax, 99.63 percent and 0.37 percent for solar and 99.46 percent and 0.54 percent for water. The measured density value was finally shown on the 16x2 LCD.

Abstract

 Abstract— This study uses 2 variations of the value of the DC 12V LED lamp power that is 12W and 15W with 3 different brands of lamp variations. Measurement of input voltage and current is carried out using a Krisbow KW06-490 DC clampmeter that has been calibrated as a standard measuring instrument and a Krisbow KW06-491 DC clampmeter that has not been calibrated as a test gauge 1 and a Multimeter Viper DT830B that has not been calibrated as a test gauge 2. Data the current and input voltage between each lamp and different lamp brands are used to calculate the value of the test lamp power and then compare it.The big conclusion from this study was found that the error value between the value of the test power or the use of DC 12V LED lamps with 12W written power on R, S, and T brand lamps was ± 51.67%, ± 70.75%, ± 61.33 %. In 15W lamps the brands R, S, and T were ± 7.20%, ± 0.53%, ± 8.27%.
