The present invention utilizes self-heating of electronic components to improve a humidity sensing part 500 with low environment resistance, such as a condensation problem and the like, and also to enhance the heat radiation efficiency of electronic components. The humidity sensing part 500 is used in an intake tube 101 of an automobile by integrating, for example, with a heating resister type mass air flow measurement device 200. A humidity sensing element is mounted on an electronic circuit board 203 in a mass air flow measurement device 200 with the temperature thereof starting to increase immediately after a sensor has been actuated. This urges the temperature of the humidity sensing element to start increasing (being heated) immediately after the sensor has been actuated. To urge the humidity sensing element to be further heated, a base plate 202 is composed of two types of materials, resin and metal. A part of the base plate 202 holding an area of the electronic circuit board 203 generating a large quantity of heat is composed of the metal. A part of the base plate 202 corresponding to the periphery of the humidity sensing part 500 which is to be heated is composed of the resin.

235 DEVICE FOR TEMPERATURE COMPENSATION IN AN ACOUSTIC FLOW METER EP99971503.0 1999-11-03 EP1135670A1 2001-09-26 DELSING,Jerker
A meter comprises a casing (1) with a fluid passage (2), in which two transducer mountings (3, 4) arranged at a distance (Lb) from each other support two transducers (5, 6) which are acoustically opposed to each other. Between the transducers (5, 6) there is a distance (Lu) over which they transmit and receive sound pulses through a fluid which in a direction (a) flows through the fluid passage (2). On the basis of the transit times of the sound pulses over the distance (Lu) both countercurrently with and countercurrently to the direction of flow (a), e.g. the velocity of the flow of the fluid is then calculated. A compensating means (8, 9) is arranged between at least one of the transducers (5, 6) and one of the transducer mountings (3, 4), said compensating means (8, 9) being made of a material having a known function of thermal expansion and having such a length that a longitudinal change, caused by a change in temperature of the fluid, of the distance (Lb) between the transducer mountings (3, 4) and, thus, of the distance (Lu) between the transducers (5, 6) is essentially compensated for by an opposite longitudinal change of the compensating means (8, 9).

Mechanism for continuously correcting volumetric flow indications of a gas meter for temperature and pressure variations is porvided with a pair of variable ratio transmissions (18,78) which operably connect an input shaft (10) rotatable according to actual volumetric flow through the meter with an output shaft (112) that drives a counter (114) indicating gas consumption. Each transmission (18, 78) preferably includes an assembly in which there are a plurality of undirectional clutches (24, 26, 28, 82) symmetrically arranged about a common axis, and a member (52, 76) relatively movable with respect to such axis for changing the ratio of the transmission. A temperature responsive device (60, 62) controls the ratio of one transmission in a manner resulting in a temperature corrected speed for such output shaft (112). A pressure responsive device (90) controls the ratio of the other transmission (78) in a manner resulting in the application of the pressure correction which is linearly dependent upon pressure to the output shaft (112) driving the counter (114), either directly or through a ratio multiplying planetary gear train.

Die Erfindung betrifft einen nach dem Schwebekörper prinzip arbeitenden Durchflußmengenmesser. Der Schwebe körper (8,9,10) ist über eine Stange (7) starr mit einem aus ferromagnetischem Material bestehenden Gewichtskörper (2) verbunden, welcher gleichzeitig den Kern einer gehäuse festen Induktionsspule (3) bildet. Die Veränderung der Induk tivität ist folglich von der Durchflußmenge abhängig. Im glei chen Sinn wie der Gewichtskörper (2) wirkt eine vorgespannte Feder (4) der Verschiebung des Schwebekörpers (8,9,10) ent gegen. Bei Anwendung eines derartigen Durchflußmengen messers zur Kraftstoffmessung in einem bewegten Fahrzeug ergeben sich dadurch Meßfehler, daß sich dem Flüssigkeits strom von außen ausgelöste Stoßwellen überlagern. Nach der Erfindung werden diese Meßfehler durch einen auf der Verbindungsstange (7) zwischen Rückstellfeder (4) und einem Gehäusebund (6) verschiebbar angeordneten Dämpfungs kolben (5) kompensiert, dessen wirksamer Querschnitt unge fähr dem des Schwebekörpers (8,9,10) entspricht, wobei der Medienzufluß (12) zwischen Schwebekörper (8,9,10) und Dämpfungskolben (5) mündet.
