[0026] The function of the platinum resistance difference quotient measurement circuit is to measure the temperature of the measured medium, and the purpose of measuring the temperature is achieved by measuring the resistance of the platinum resistance. This temperature is used to look up the table to calculate the density of the measured medium, as well as the pipe diameter D, the opening diameter d of the throttling element and the diameter ratio β under working conditions.
[0027]The measured platinum resistance RT from the outside is connected to the meter terminal in a three-wire system, and then connected to the analog switch circuit by the internal connection similar to the internal standard resistance RH and RL. When working, the P1.1 and P1.2 ports of the single-chip microcomputer control the position selection terminals A and B of the 4052 through the driver 7406 and the photocoupler TLP521-2, and connect the constant current source I1 to RH, RL and Rt in turn to genera...
