Volumetric determination of contaminated liquid or gaseous media

Claim 1

A method for the discontinuous measurement of the volume of liquid and gaseous media, respectively, contaminated with solids, by alternately flowing a pure medium of an accurately measured volume and a contaminated medium of unknown volume which is to be measured through a measuring device delivering its measured results in the form of pulses; storing the number of pulses delivered by the passage of said pure medium through the measuring device; flowing contaminated medium through the measuring device until the number of pulses delivered by the measuring device corresponds to the number of stored pulses; flowing said pure medium through the measuring device and storing the number of pulses delivered; comparing the last number of pulses stored with the number of pulses delivered and stored on the previous passage of said pure medium through the measuring device; modifying the number of pulses last stored by half the difference between the two stored numbers of pulses; and passing, in the next following metering cycle, contaminated medium through the measuring device until the number of pulses delivered by the measuring device corresponds to the modified number of pulses.

Claim 2

A method for the discontinuous measurement of the volume of liquid and gaseous media, respectively, contaminated with solids, by alternately flowing a pure medium of an accurately measured volume and a contaminated medium of unknown volume which is to be measured through a measuring device delivering its measured results in the form of pulses; storing the number of pulses delivered by the passage of said pure medium through the measuring device; flowing contaminated medium through the measuring device until the number of pulses delivered by the measuring device corresponds to the number of stored pulses; flowing said pure medium through the measuring device and storing the number of pulses delivered; comparing the last number of pulses stored with the number of pulses delivered and stored on the previous passage of said pure medium through the measuring device; modifying the number of pulses last stored by half the difference between the two stored numbers of pulses; and passing, in the next following metering cycle, contaminated medium through the measuring device until the number of pulses delivered by the measuring device corresponds to the modified number of pulses.

Claim 3

An apparatus for the discontinuous measurement of the volume of liquid and gaseous media, respectively, contaminated with solid matter, the apparatus comprising a. a first pipe provided with a first flowmeter permitting the supply of metered quantities of a pure medium and with a first automatically actuated valve; a second pipe provided with a second automatically actuated valve, the first pipe and the second pipe leading into a third pipe provided with a second flow meter permitting the supply of metered quantities of a contaminated medium; b. a first processing unit comprised of a first counter connected to the first flow meter in said first pipe; a first presetter, and a first comparator; said first comparator being connected to the first automatically actuated valve, to the first counter and to the first presetter, and closing the first automatically actuated valve in said first pipe when a quantity of pure medium adjusted in the first presetter has passed through the first flowmeter; c. a second processing unit comprised of a second counter connected to the second flowmeter in said third pipe, a first register, and a second comparator; the second comparator being connected to the second automatically actuated valve, to the second counter and to the first register, and closing the second automatically actuated valve in said second tube when an amount of contaminated medium which has passed through the second flowmeter in said third pipe has produced a number of pulses which is equal to the number of pulses stored in the first register from the previous passage of the quantity of pure medium through the second flowmeter; d. a third processing unit comprised of a second register, a third counter, a third comparator, a clock generator, and a divider, said divider being connected to the clock generator, to the third counter, and to the second counter of the second processing unit; the second register being connected to the third counter, to the third comparator, to the first register, and to the second counter; and the third comparator being connected to the clock generator.
