Abstract: For continuous measurement of the dynamic fuel consumption of an internal combustion engine with a venting tank (10) which is disposed in a return line (11) from the outflow side (12) of the fuel system (7) and is also connected to the intake line (13) to the fuel system, a filling level regulator (15) is provided at a connection of the venting tank (10) and has a circulation pump (22) as well as a control valve (9) connected thereto, through which the flow passes continuously, and which is opened more or less as a function of the filling level to be regulated. Thus apparent consumptions occurring in specific operating states of the internal combustion engine can be avoided but can also be taken into account as corrections.

Abstract: In a method for determining the flow rate of fluids using the ultrasonic transit time method, the flow speed and therefrom the flow rate of the fluid is determined from the transit time of ultrasound signals through the measurement section. In order to take into account the change in the transmission function of the ultrasonic converters, which change acts as a drift of the measurement variable, the transmission function of the measurement section is determined at least approximately, and at least one ultrasonic transit time is corrected by means of a correction value that is determined from the group transit time of the transmission function.

Abstract: A method for continuous measurement of the dynamic fluid consumption of a consumer by use of a two-way flow sensor, particularly the measurement of gaseous or liquid fuel, and possibly a conditioning device, whereby the pressure is reduced to a constant exit pressure downstream from the flow sensor. A minimum quantity of fluid is fed through the pressure regulator at any desired time whereby fluid is continuously returned in variable quantities from the region of constant exit pressure to the region between the flow sensor and the pressure regulator to make possible a continuous, accurate and timely highly defined consumption measurement with controlled exit pressure for the fluids using an open system which is able to maintain pressures in the entire line system even at highly dynamic consumption changes and which does not allow the formation of a multiphase flow.

Abstract: A method for the continuous measuring of dynamic fluid consumption using a continuously-operating flow sensor with variable pressure drop wherein the pressure downstream of the flow sensor is adjusted to a constant value by a pressure regulator, and when the pressure downstream of the pressure regulator exceeds a certain level, recycling fluid back into the pressure regulator in an amount that corresponds to the volume causing the excess pressure.

Abstract: In a method for continuous measuring of dynamic fluid consumption, particularly fuel, the pressure beyond the flow sensor is adjusted to a constant value by means of a pressure regulator by using a continuously-operating flow sensor with variable pressure drop, preferably a mass flow sensor. Fluid is guided into the pressure regulator after exceeding a discretionary pressure to allow continuous, accurate, as well timely and highly discriminating consumption measuring with regulated exit pressure for the fluid even at a back-flow of short duration or during temperature-related expansion of the fluid. A pressure regulator (9) provided for this purpose has a housing (41, 42), which contains an element (40) biased by a changeable force whereby the element (40) is coupled to a valve arrangement (49, 50) that is also arranged in the housing (41, 42) for the fluid to build up pressure therein. The pressure regulator (9) contains a catch volume for the fluid.

Abstract: A method and device for continuous measuring of dynamic fluid consumption, particularly gaseous or liquid motor fuel, employs a continuously operating flow sensor with variable decrease in pressure, preferably a mass flow sensor. The pressure downstream from the flow sensor is adjusted to a constant value by changing the admission pressure of the sensor to make possible accurate and rapid consumption measurements with controlled output pressure for the fluid by means of an open system, and also to allow simultaneous measuring of at least a short-time return flow. The device includes a preferably controllable pump (6) possibly a conditioning device and a tank (2), and continuously operating flow sensor (7) for the fluid, preferably a Coriolis sensor, whereby a line branches off behind the sensor (7) leading to a pressure sensor whose output is connected to a control device that triggers the devices to influence the volume flow upstream from the sensor (7).

Abstract: An ultrasonic gas flowmeter includes a measuring pipe with flowing gas, transmitting and receiving sound transducers, transmission and reception electronics, and evaluation electronics. The sound transducers (7, 8, 9, 10) are designed as capacitive electro-acoustic ultrasonic transducers to construct a flowmeter with improved capacity, especially in view of temperature stability and the reduction and consideration of a temperature profile. Devices (5, 6) are provided to level the gas temperature profile and to minimize the influence of the temperature profile on the flow measurement. A more accurate and dependable detection of the volume flow or the mass flow of gases is to be achieved, especially in highly dynamic flows, for the method of determining the flow of gases whereby the mean flow velocity is determined and the flowing gas quantity is determined with highly synchronized resolution from the two transit times of two acoustic signals.
