    摘要： A dispenser unit for a non-gaseous flowable material has a holder for the flowable material with an aperture therein through which the material can be transferred between into and out of the holder, and a flow meter for measuring flow of the material during transfer. The flow meter has a sensor, for example a differential pressure meter which determines a pressure difference between two locations which are vertically spaced from each other within the holder, one above and one below the surface of the material, at a number of times during the transfer. The meter emits a signal indicative of the flow from a calculation of the rate of change of the determined pressure difference.

    摘要： In a fresh gas system and a method for vaporizing a liquid anaesthetic in an anaesthetic machine, a gas preparation unit prepares a flow of fresh gas having a gas mixture from at least two sources of gas, the gas mixture is passed through a vaporizer where it picks up a quantity of anaesthetic related to the viscosity of the gas mixture. A control device controls the gas preparation unit. An arrangement is connected upstream from the vaporizer and is connected to the control device, for determining the composition of the gas mixture. The control device compensates the fresh gas system for the gas mixture's composition so that a specific amount of anaesthetic is always picked up by the gas mixture, regardless of the mixture's composition.

    摘要： A dosing device for regulating the concentration of a liquid vapor, produced by vaporizing liquid from a liquid source, in a carrier gas has on-off valve which is automatically operable by a valve controller and which is connectable to one or both of the liquid and the carrier gas. A flow meter is provided in the flow path of the liquid and generates an output signal proportional to the flow of the liquid supplied for vaporization. This signal is supplied to the controller which cooperates with the valve to automatically regulate the supply of one or both of the liquid or carrier gas dependent on the output signal.
