Abstract
Methods, apparatuses, and computer program products associated with flow sensing devices are provided. An example flow sensing device may comprise a controller component in electronic communication with a flow sensing component that is configured to: monitor at least one flow sensing component output, detect an air bubble at a location adjacent a surface of the flow sensing component based at least in part on the at least one flow sensing component output, and determine whether the air bubble satisfies an air bubble condition defining one or more predetermined characteristics.
Claims16
A flow sensing device comprising:
- a housing;
- a flow sensing component disposed at least partially within the housing, wherein the flow sensing component is configured to make direct contact with a flowing media in a flow path of the flow sensing device;
- and
- a controller component comprises a processing circuit and a memory in electronic communication with the flow sensing component that is configured to:
- monitor at least one flow sensing component output from the flow sensing component,
- detect an air bubble at a location adjacent a surface of the flow sensing component based at least in part on the at least one flow sensing component output, wherein monitoring the at least one flow sensing component output comprises:
- determining whether the at least one flow sensing component output is less than a previous value of the at least one flow sensing component output;
- and
- determining whether the at least one flow sensing component output is equal to a predetermined minimal value;
- determine an air bubble pass condition based on the at least one flow sensing component output being equal to the predetermined minimal value;
- in response to determining the air bubble pass condition, initiate a bubble dwell timer;
- in response to determining the air bubble pass condition, generate an indication that the air bubble is present at a location adjacent the surface of the flow sensing component;
- determine a minimum permissible dwell time value based on a previous flow rate value and a width of the flow sensing component:
- retrieve a maximum allowable dwell time value;
- and
- in an instance in which the maximum allowable dwell time value is greater than an air bubble dwell time value, generate an air bubble retention indication.
