ABSTRACT:
An adding flowmeter comprises a liquid chamber and is divided into two chamber parts by a membrane fixed to a slide which is able to move along a rod. The rod controls a slide valve for the supply and discharge of liquid to and from each of the chamber parts. By means of two abutments against which the slide bears on the rod, the membrane is able to move this rod in order to reverse the supply and discharge connections of the flowmeter so that the membrane carries out a reciprocating movement, filling one of the half-chambers and emptying the other, then vice versa. The number of changes of state of the slide valve are counted to determine the volume of liquid which has circulated in the flowmeter.
