Title: High temperature coriolis mass flowmeter
Inventor: DONARUDO RIIDO KEEJI
IPC: G01F1/84
Filed: 1989-10-12
Abstract: PURPOSE: To measure high temperature without any cooling system by providing a plurality of speed sensors, monitoring the imbalanced distortion of a flow pipe, and measuring flow rate, based on the generated imbalanced distortion signal. CONSTITUTION: A housing 14 surrounds flow pipes 11 and 11' watertightly and arranges an inert gas. A fluid for measuring a mass flow rate passes through the flow pipes 11 and 11' and is formed by an alloy which produces no carbide settlement in a temperature range that is equal to or more than 260 deg.C. Also, the flow pipes 11 and 11' have a uniform wall thickness, is suspended so that they can be vibrated, and vibrate in response to the drive signal of a high-temperature drive means. Then, a fluid flows inside the flow pipes 11 and 11', which are distorted imbalancedly due to coriolis force, where speed sensors 17 and 18 monitor imbalanced distortion, and generate an imbalanced distortion signal. The signal is detected as a flow by a detection coil 22 of a magnetic drive assembly system 16.  In this case, even if the temperature of the fluid becomes high, no cooling system is required, thus measuring the flow rate easily.

Abstract: PURPOSE: To improve fuel consumption ratio and suppress increase of exhaust temperature in the case that a rich air-fuel ratio is brought about by stopping feedback control when a high load condition of an engine succeeds for a specified time, by setting the specified time according to deviation between a fuel supply rate and a specified reference value. CONSTITUTION: An ECU 20 determines an operation condition as in a feedback control operation area or an open loop control operation area according to oxygen density in exhaust gas based on input of signals from a throttle valve opening sensor 18, an engine speed sensor 32 and an O2 sensor. A fuel injection time of a fuel injection valve 22 is computed according to the determination result. After a specified high load state of an engine succeeds for a specified time, the feedback control is stopped, for bringing about a rich air-fuel ratio. In such a control, the specified time which is a condition for stopping the feedback control is set according to deviation between a fuel supply rate and a specified reference value.
