摘要：
A flow indicator having an element responsive to liquid flow and a bypass channel for gas flow, the bypass channel being offset from the liquid-responsive member in a direction taken by gases through the device whereby the flow-responsive member is responsive to liquid flow and not to gas or gas-liquid flow. A cooperating external signal transmitting element is mounted for variable positioning on the device.
