Abstract: What is described is a throughflow-quantity limiter for a pipeline carrying water, oil or the like, with the use of a shut-off member and of a flow-detection member with a contact-maker for the transmission of pulses to a time relay which acts on the shut-off member, in which through-flow quantity limiter a bypass line, in which a flow-detection member is arranged, is provided parallel to a portion of the pipeline which follows in a throughflow direction a portion of the pipeline having a shut-off member. As a result, the flow-detection member is capable of already reacting to minimum throughflow quantities with uniformly high accuracy in the case of pipeline cross-sections of varying size, both in normal operation and in the event of a fault.

Flow limit system for a liquid flow through a pipe
Bartling Werner
- 05 Jan 2000
TL;DR: In this paper, the flow limit system operates so that the control (7) generates a closing command to the shutoff (1) when the pressure switch (5) registers a pressure which is below the nominal flow pressure for flow limit (4), during an uninterrupted time span.

Safety device for domestic water supply - detects leak or open tap by uniformity of flow to operate shut-down valve
Krieger Theo
- 08 Oct 1981
TL;DR: In this article, a switch responsive to the water flow is used to operate a timer with the shut-down valve closed automatically is the flow remains the same throughout the timer interval, where the variations in the flow are detected by two sensors (7,8) comprising temp. dependent resistors positioned one behind the other in the water line and connected to a measuring bridge.
