Embodiment Construction
[0029] The present invention includes two parts: a temperature density sensor and an intelligent display record controller. The principle of the density probe is: the top sensor and the bottom sensor form a differential pressure sensor, and the top sensor and the bottom sensor respectively detect the pressure of the upper and lower points through the isolation diaphragm. The vertical height between them is H. By precisely calibrating the pressure difference between the top sensor and the bottom sensor and measuring the H value, the static pressure principle of liquid substances is used: density = pressure / height, and then the linearity is adjusted by the software programmed into the microcontroller. Errors, temperature errors and other non-correlation errors are precisely corrected to achieve accurate measurement of density parameters. Referring to Fig. 1, the intelligent display recording controller 1 is connected to the density sensor through a mounting flange 6, the density ...
