Abstract
A gas filter clogging detection system for monitoring filter performance and condition based on indicators of the accumulation of dirt and other particles on a filter positioned in a gas conduit, in which a notification system provides alerts and reports when the amount of clogging reaches a pre-determined threshold.
Claims19
A notification system for use with a filter clog detection system, the filter clog detection system being configured to monitor the condition of a filter in a gas conduit operatively attached to a gas blower, the gas blower having power to produce a first gas flow, comprising:
- a sensing system for measuring a property within the conduit, wherein a condition of the gas filter affects the value of the measured property;
- a processor configured to execute instructions for comparing a first value of the measured property when the gas filter is in a first state to a second value of the measured property when the gas filter is in a second state, and
- a networking module configured to transmit signals to a server, the signals representing information related to a condition of the filter based on comparing first and second values;
- wherein the networking module is configured to transmit signals automatically at predetermined intervals;
- and,
- wherein the sensing system comprises a first sensor and a second sensor, only one of which is connected to a heater, the sensors being configured to maintain a temperature difference between them, and wherein the measured property is a voltage reading for maintaining the temperature difference.
A method for providing notifications with a filter clog detection system, regarding the condition of a filter in a gas conduit operatively attached to a gas blower, the gas blower having power to produce a first gas flow, the sensing system being configured to measure a property within the conduit, wherein a condition of the gas filter affects the value of a measured property, the method comprising:
- configuring the sensing system for positioning in a location proximal to a gas filter:
- configuring a processor to compare a first value of the measured property when the gas filter is in a first state to a second value of the measured property when the gas filter is in a second state;
- and
- configuring a networking module to transmit signals representing information about a condition detected by the sensing system to a server, wherein the information is related to a condition of the filter or a condition of the sensing system,
- wherein the networking module is configured to transmit signals automatically at predetermined intervals;
- and
- wherein the measured property is a voltage reading for maintaining a temperature difference between a heated sensor and an unheated sensor positioned within the sensing system.
A notification system for use with a filter clog detection system, the filter clog detection system being configured to monitor the condition of a filter in a gas conduit having an interior wall surface and being operatively attached to a gas blower, the gas blower being configured to produce a first gas flow, comprising:
- a sensing system for measuring a property within the conduit, wherein a condition of the gas filter affects the value of the measured property;
- a processor configured to execute instructions for comparing a first value of the measured property when the gas filter is in a first state to a second value of the measured property when the gas filter is in a second state, and
- a networking module configured to transmit signals to a server, the signals representing information related to a condition of the filter based on comparing first and second values;
- wherein the networking module is configured to transmit signals automatically at predetermined intervals;
- and,
- wherein the sensing system comprises a sensing tube having an inlet arranged to receive gas flow from outside the gas conduit, and an outlet in fluid communication with an interior of the gas conduit, wherein the processor correlates filter clogging with the lowering of temperature inside the sensing tube as gas from outside the gas conduit flows into and through the sensing tube.
