    摘要： The method is based on the fact that the particular components are conveyed through separate pipes into a mixing chamber. By measuring the transit time in at least one of the pipes the flowrate can be measured. The flow in the other pipes which is in a fixed ratio to the first flow is then adjusted automatically. For measuring the transit time a heat pulse is injected in at least one of the pipes and the transit time of the heat impulse is measured. The so-measured transit time is converted into an inversely proportional voltage and the flowrate in the other pipes is adjusted proportionally to this voltage. An apparatus is provided for practicing the method. The apparatus comprises flow measuring elements which are electrical connected to control devices which operate flow control devices in the pipes leading to the mixing chamber.

    摘要： The instant invention provides a method for determining the streaming velocity of a streaming liquid by injecting a thermopulse into the liquid and measuring its transit time. The pulse is detected by its ascending flank at downstream points and by its ascending or descending flank at its point of injection. For short transit times, provision is made to eliminate the heat up time of the heating wire imparting the pulse from the transit time measurement. The liquid may stream continuously or discontinuously, and if the later, provision is made to delay measurement on initiation of flow until the flow pattern has stabilized. The time is determined by counting pulses from a pulse generator during the period the pulse is traveling between the point of injection and a detection point or between two detection points.
