Abstract: Flow sensors are provided that can monitor flow conditions. The flow sensor includes a gauge that provides a first level of information about flow through the sensor, and an indicator associated with the gauge that can provided a second level of information about flow through the sensor. The indicator might be in the form of a dial that can rotate about the gauge and might include a locked position for monitoring flow and an unlocked position to rotate the dial about the gauge to reposition the dial. Vanes in the flow sensor remove turbulence in the flow sensor to settle any noise that would otherwise register in the first level of information about flow through the sensor. The plunger with a rounded upstream face also helps to settle any such noise.

Abstract: Flow sensors are provided that can provide both leak detection and flow monitoring. The flow monitoring enables a determination whether there are blockages or leaks in a fluid system during normal operation of the system. The leak detection enables detection of leaks when the system is shut off. The flow sensors can use a frusto-conical flow guide to provide a more compact flow sensor. The flow sensor components can be designed to retrofit existing filter assemblies.
