ABSTRACT:
The apparatus for controlling a discontinuously flowing material flow and for measuring a value proportional to this material flow and a further physical magnitude serves particularly for measurement of heat quantities, preferably in central heating apparatus. For this it utilizes at least a self-regulating flow valve (16) for allowing flow-through of a constant material stream (2) and an open/closed material through-flow valve (6) connected in series with the flow valve (16) and controlled by a third physical magnitude (T.sub.o). A servo control device is associated with the material through-flow valve (6). In this the material flowing through the through-flow valve (6) serves as a servo control medium. A thermostat (9), a time register, a pH gage, a concentration gage or a level gage serves for control of the servo device. By means of an apparatus of this type there is solved the problem of measuring in the simplest possible manner the product of two magnitudes that are connected with one another, for example, material quantity and temperature, as this is desirable, for example, for measurement of heat quantities in portions of central heating systems or for simultaneously metering out predetermined material quantities at predetermined times.
