Title: Micro flow sensor
Inventor: KOTANI HARUO
IPC: G01F1/696
Filed: 1982-10-30
Abstract: PURPOSE:To improve homogeneity, reliability, and productivity by providing >=2 P-N junctions in a resistive base board, feeding a current to the base board and heating them, and bringing this base board into contact with gas to be measured and measuring the flow rate of the gas from the difference between voltages developed at the two P-N junctions. CONSTITUTION:When the current I is fed to the base board 14, the board is heated up to T deg.K and two P-N junctions 20 and 21 are also heated. Further, a forward current If is flowed to those P-N junctions 20 and 21 from terminals 18c-18f to develop voltages proportional to absolute temperature T deg.K between the terminals 18c and 18d, and 18e and 18f. When the gas to be measured is flowed through a capilary 13, heat is absorbed by the gas greatly at an upstream point A of the base board to heat the gas, and a relatively small amount of heat corresponding to the difference between the temperature of the heated gas and the temperature of the board 14 at a downstream point B is absorbed at the point B. The difference in temperature between the points A and B of the board varies depending upon the flow rate, so the voltage Vd of both P-N junctions which reflects the temperature is measured to measure the gas flow rate.

The BRF 42 has a transfer function of 1/H (w), where H (w) shows the transfer function of the roll-off. In order words, the BRF 42 having an inverse characteristic 1/H (w) of the roll-off is put before the circuit 36. As a result, the phase transition and then the unwanted waves that are caused by the roll-off characteristic can be suppressed.
