Title: Correction of fluid composition for flowmeter
Inventor: ROBAATO II HIGASHI
IPC: G01F1/68
Filed: 1989-12-15
Abstract: PURPOSE:To enable the removal of errors generated by a change in composition of a flow velocity measured value of various gas fluids to be measured by determining an uncorrected value of a zero-weight flow rate of a fluid to be measured concerning an output of a micro air velocity sensor. CONSTITUTION:A second micro air velocity sensor not exposed direct to a liquid is used and is made to communicate with a fluid at a relatively far position to be used to measure a fluid parameter detected in static condition. This sensor can measure a heat conductivity K and a specific heat cp directly and also can determine a density (q) with a single measuring device from these characteristic values of a sample to be measured. Then, a certain relationship exists between weight flow rates cp, k and q which are corrected by subtracting a zero-weight flow rate M0, namely, a value as obtained when a flow rate is zero. In other words, when the specific heat cp, the heat conductivity (k) and the density (q) are known, a correction of a formula of M = M0cp/k (3.8+q) can be applied for a total weight flow rate M concerning the zero weight flow rate M0.
