Rotary vane positive displacement (PD) flowmeter is included in the category of flowmeter that works using the principle of volumetric flow operation. Temperature is one of the variables that affect the process of measuring the volume of a fluid. Changes in fluid temperature will result in changes in the volume of fluid in the form of shrinkage or expansion. This research aims to design and implement a prototype of rotary vane PD flowmeter data acquisition mechanism with also include measurement of temperature as a variable compensation. Fluid flow is simulated using DC motors that rotate the chamber model of rotary vane PD flowmeter prototype and the optical encoder disk. Changes in environmental temperature are simulated using a heating element. Data obtained from Arduino UNO processed at the interface program and then presented in the form of numbers, tables, and graphs. Temperature value is used as the reference standard is 15°C. Testing is done by providing a variety of setting value of expansion coefficient at 0,0007/°C and 0,001/°C, flow rate at 335 L/min, 506 L/min, dan 556 L/min, and also temperature setting value at 30°C, 35°C, 40°C, 45°C, and 50°C. From the experimental results obtained the highest value of the difference in the total volume as the results of compensation is from the experiment with setting the value of expansion coefficient at 0,001/°C, flow rate at 556 L/min, and temperature at 50°C which is equal to 65,854 liters, while the lowest value is from the experiment with setting the value of expansion coefficient at 0,0007/°C, flow rate at 335 L/min, and temperature at 30°C which is equal to 10,530 liters. At the same value of volume and temperature, the higher the coefficient of expansion of a fluid, the higher the value of the compensation given conversely.
