变量名称: sc_dpa
变量ID: 0x4098
变量标签: Density parm. A
变量描述: Density parameter A is a constant found under the density calibration. This constant is used in the formula to calculate the density of the fluid in the sensor. Density (kg/m3 ) = A + B (1 + Density TC x temp.) * (1/(fr)^2). A = Density parameter A (kg/m3). B = constant. Density TC = Sensor`s density temperature coefficient ( %/DegC). fr. = the sensors resonance freq(Hz). Standard sensors without density calibration have average values stored in the sensorprom to be able to monitor the density.
