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.
Claims11
A flow sensor comprising:
- an inlet;
- an outlet;
- a flow path from the inlet to the outlet;
- a flow guide along the flow path, the flow guide having an inner surface;
- a piston head moveable in the flow guide based on an amount of fluid flowing through the flow sensor;
- and
- at least one vane upstream of the piston head to reduce turbulence from the flow contacting the piston head, the at least one vane having an upstream edge, a downstream edge, and a vane body extending therebetween, and the upstream edge and the downstream edge extending into the flow guide from the inner surface.
