| titleOfInvention | Architecture of novel thermal pulsed micro flow meter |
| abstract | This invention discloses the architecture of a novel thermal pulsed micro flow meter, which is configured according to the procedures described below. A micro channel is set up for testing fluid passing through; a heater is located upstream from the micro channel to heat up the testing fluid flowing through the micro channel, and a thermal sensor S0 is installed downstream of the heater and within the micro channel; and further downstream at a distance of L1 from thermal sensor S0 there is another thermal sensor S1, where L1 value is derived from the formula: dF=(A*L1)*{1/T-1/(T+dT)}, where A is the cross-sectional area of the micro channel; T is the time difference expressed by T = (A*L1)/F1; F1 is the maximum flow rate allowed in the testing parameter; dT is the thermal pulse signal distortion resolution, dF is the resolution required by the testing unit; the smallest flow rate F1<min> of thermal sensor S1 is expressed by the formula: F1<min>=(A*L1)/R, where R is the minimum response time required by the flow meter. Thermal sensors S2, S3, íK, Sn (n is a positive integer) are installed downstream relative to the heater and upstream relative to the thermal sensor S1 until the calculated F(n)min is less than a predetermined value d, where the distance Ln between thermal sensor Sn and S0 is calculated from the formula: dF=(A*Ln)*{1/T-1/(T+dT)}, where A, Ln, dT and dF have been previously defined, T=(A*Ln)/{F(n-1)min+<alpha>}, and <alpha> is an adjustment value. |
