Abstract

Embodiments herein relate to air filtration monitoring systems that can measure air volume and/or air velocity. In an embodiment a monitoring system for industrial dust collectors is included having a pressure sensor and a control circuit, wherein the control circuit can be in signal communication with the pressure sensor. The monitoring system can store a previously measured air volume value and/or air velocity value and can calculate real time air volume values and/or real time air velocity values using data from the pressure sensor and the previously measured air volume value and/or air velocity value. Other embodiments are also included herein.

First claim

1 . A monitoring system for industrial dust collectors comprising:
a pressure sensor; and a control circuit, wherein the control circuit is in signal communication with the pressure sensor; wherein the monitoring system stores a previously measured air volume value and/or air velocity value; and wherein the monitoring system calculates real time air volume values and/or real time air velocity values using data from the pressure sensor and the previously measured air volume value and/or air velocity value.

2 . The monitoring system of claim 1 , wherein the monitoring system calculates a real time value for air volume and/or air velocity by multiplying the previously measured air volume value and/or air velocity value by the square of the quotient of a current relative airflow value divided by a relative airflow value measured at the time of the previously measured air volume and/or air velocity, wherein relative airflow values are derived using data from the pressure sensor.

3 . The monitoring system of claim 1 , wherein the monitoring system calculates a real time value for air volume and/or air velocity by multiplying the previously measured air volume value and/or air velocity value by the square of the quotient of a current pressure value divided by a pressure value measured at the time of the previously measured air volume and/or air velocity.

4 . The monitoring system of claim 1 , the pressure sensor comprising a static pressure sensor.

5 . The monitoring system of claim 4 , wherein the static pressure sensor is configured to measure pressure within a main duct portion of the industrial dust collector.

6 . The monitoring system of claim 4 , wherein the static pressure sensor is configured to measure pressure within a branch off of a main duct of the industrial dust collector.

7 . The monitoring system of claim 4 , wherein the static pressure sensor is configured to measure pressure within a duct of the industrial dust collector upstream from an air filter.

8 . The monitoring system of claim 4 , wherein the static pressure sensor is configured to measure pressure within a duct of the industrial dust collector or in fluid communication with the industrial dust collector having a diameter of 4 to 48 inches.

9 . The monitoring system of claim 1 , wherein the pressure sensor is configured to be mounted on, mounted in, and/or mounted in fluid communication with an industrial dust collector.

10 . The monitoring system of claim 1 , the pressure sensor comprising a plurality of static pressure sensors, wherein the plurality of static pressure sensors are configured to measure pressure within air ducts associated with different industrial air collectors.

11 . The monitoring system of claim 1 , wherein the monitoring system is configured to issue an alert if the real time air volume values and/or real time air velocity values are outside of a target range.

12 . The monitoring system of claim 11 , wherein the system is configured to receive input from a system user regarding the target range.

13 . The monitoring system of claim 1 , wherein the monitoring system is configured to issue an alert if the real time air volume values and/or real time air velocity values are outside of a target range regardless of relative airflow values.

14 . The monitoring system of claim 1 , wherein the previously measured air volume and/or air velocity is input into the system based on a measurement taken manually.

15 . The monitoring system of claim 1 , wherein the previously measured air volume and/or air velocity is input into the system based on a measurement taken using at least one of a pitot tube, a vane anemometer, or a hotwire anemometer.

16 . The monitoring system of claim 1 , wherein the monitoring system is configured to transmit real time data to a remote computing resource.

17 . The monitoring system of claim 16 , the real time data comprising at least one selected from the group consisting of real time pressure data, real time air volume values, and real time air velocity values.

18 . The monitoring system of claim 1 , wherein the real time air volume values are in the range of 500 cfm to 50,000 cfm.

19 . The monitoring system of claim 1 , wherein the pressure sensor and the control circuit are co-located with an industrial dust collector being monitored.

20 . A method of monitoring industrial dust collectors comprising:
storing a previously measured air volume value and/or air velocity value; measuring real time pressure values in an area in fluid communication with an industrial air collector; and calculating real time air volume values and/or real time air velocity values using the real time pressure values and the previously measured air volume value and/or air velocity value.
