    摘要: A method of determining whether a scale in a fluid handling device needs to be calibrated includes weighing a storage tank of fluid a first time with a scale, transferring the fluid from the storage tank to an area of known volume, weighing the storage tank at a second time with the scale, after fluid has been moved to the area of known volume, determining the pressure of the fluid in the area of known volume with a pressure sensor, calculating a temperature of the fluid in the area of known volume with the determined pressure, calculating the weight of fluid in the area of known volume based on the calculated temperature, calculating the weight of fluid in the area of known volume based on the determined temperature and temperature, comparing a difference in weight of the storage tank between the first and second weighing times with the weight of the fluid in the area of known volume; and sending a first signal to a user indicating a calibration of the scale is not needed if the difference between the compared weights of the fluid is within a predetermined range.
