How to check status of long running http task with airflow?

· In Airflow, Sensors are used just like Operators (sensors are operators). So you can create a job like this: http_post_task -> http_sensor_task -> success_task Where http_post_task will trigger a job, http_sensor_task will check periodically to see if the job is done ( GET request the microservice and check for 200, maybe?), and success_task will execute after the http_sensor_task …

How to Troubleshoot a Mass Airflow Sensor - AxleAddict

· To test the MAF sensor, you'll need to have the electrical connector plugged in to the sensor. So check if you can backprobe the wires. If not, you'll need to pierce the wires using a pin when conducting your tests. If you use the later method, wrap the pierced wires with electrical tape when you're done with the tests, to prevent rust from creeping into the wires.

Best Ways to Measure HVAC Duct Airflow - Degree Controls Inc

Sensor Pole Arrays reduce set-up time by eliminating complex fixturing that goes along with making multiple measurements across a plane, and Sensor Pole Arrays increase test repeatability. Very little impedance is imparted to the air-flow profile. The Sensor Pole Array can be used with data acquisition instruments to aggregate sensor data. The data acquisition instrument is paired with ...
