| The invention relates to an air mass meter with a sensor element, wherein an air mass flow to be measured moves across the sensor element and wherein the sensor element is formed as a micro-electro-mechanical system having a membrane, on which a heating element is formed. An electrical measuring resistor and at least two electrical comparison resistors are arranged upstream and downstream of the heating element in the direction of the air mass flow, and a first temperature sensor element and a second temperature sensor are formed by the electrical connection of a respective measuring resistor to at least two comparison resistors. In order to eliminate distortion of the measuring results due to contamination of the sensor element, or at least to keep the distortion within narrow limits, the first temperature sensor element is formed as a series circuit of resistors on the sensor element, with a measuring resistor arranged upstream of the heating element relative to the air mass flow and two comparison resistors arranged downstream of the heating element relative to the air mass flow, and the second temperature sensor element is formed as a series circuit of resistors on the sensor element, with a measuring resistor arranged downstream of the heating element relative to the air mass flow and two comparison resistors arranged upstream of the heating element relative to the air mass flow. | ||||||

| The inline measuring device comprises a vibratory-type transducer and a measuring device electronics electrically coupled with the vibratory-type transducer. The vibratory-type transducer includes at least one measuring tube being inserted into the course of a pipeline and serving for conducting a mixture to be measured. An exciter arrangement acting on the measuring tube for causing the at least one measuring tube to vibrate and a sensor arrangement sensing vibrations of the at least one measuring tube and delivering at least one oscillation measurement signal representing oscillations of the measuring tube. The measuring device electronics delivers an excitation current driving the exciter arrangement. Further, the inline measuring device electronics is adapted to produce a measured value representing the physical, measured quantity of the mixture to be measured. Therefor, the measuring device electronics estimates from the excitation current and from said at least one oscillation measurement signal a Coriolis coupling coefficient. This Coriolis coupling coefficient corresponds with an instantaneous coupling between a first natural eigenmode of the measuring tube currently driven by the exciter arrangement and a second natural eigenmode of said measurement tube. In this second eigenmode the measurement tube has an eigenform corresponding with a mode of vibration caused by Coriolis forces induced in the flowing mixture. Due to a variation of a concentration of at least one of a component of the mixture the Coriolis coupling coefficient varies in time. | ||||||

| 206 | TEMPERATURE COMPENSATION FOR PNEUMATIC PUMPING SYSTEM | PCT/US2008068948 | 2008-07-02 | WO2009006490A3 | 2009-06-25 | HUITT BRUCE; VINCENT DOUGLAS; HECHT GIDEON |
| Temperature compensation is applied to correct for temperature mismatch between a reference chamber and a disposable chamber in a pneumatic pumping system for dialysis fluid for peritoneal dialysis. The mismatch creates an error in the calculation of pumping volume of dialysate fluid. Applying a correction for the temperature mismatch helps to more precisely control the volume of dialysate that is metered to the patient. Also disclosed are ways to keep temperatures constant and to use temperature sensors to accurately measure the temperatures of the chambers. In other aspects, the temperature of the dialysate fluid itself may be measured and used to apply a correction to the volume of fluid that is pumped to the patient. | ||||||

| A small and light-weight flowmeter realizes the compensation of a zero point drift. A mass flowmeter includes: a centrifugal force/centripetal force detection strain gauge adhered to a part acted upon by a centrifugal force or a centripetal force of fluid in a pipe line in which the fluid flows and a flow rate zero point drift compensation strain gauge adhered to a position different from that of the centrifugal force/centripetal force detection strain gauge. A pulse wave propagation time between the two points is used to compensate a zero point drift of a flow rate. | ||||||
