Flow Troubleshooting Steps
- Distance between flow sensor and aircard?
- Type of wire being used as communication wire?
- Gauge - ______________________
- Type - _______________________
- Length - ______________________
i. Any splices? Waterproof splices at ends and any splice in between?
- Ohmn out the wire path
- Disconnect from aircard and tie these together
- Disconnect at flow sensor
i. 10 ohms or less is desirable
- Tap test at aircard
- Set flow sensor on smartlink to CUSTOM> 1 PPG. Save. SEND.
- Tap red and black wires form aircard together directly into the aircard – without any other wires connected
- MUST run a zone, any zone to get controller and aircard to register flow
i. Turn on zone, wait at least 1 minute,
ii. Begin tapping and tap for at least 2 mins (the more taps the better)
- Note what zone was used for test
iii. Then wait one minute and do a normal receive from smartlink to see if flow data was recorded
iv. If no data was recorded, aircard is suspect and will need to be repalced
- If flow is detected, wire communication wires back to aircard
- Repeat tap test at end of wire path (flow sensor disconnected)
- Follow same process as above
- If no flow recorded, wire path is suspect. Utilize 521 (with all components disconnected) to locate break/damage in wire path and repair.
- If 2nd test was successful, wire all components together and run tests as normal to see if flow is registers on smartlink.
- If still no flow registering, flow sensor is suspect.
i. Remove flow sensor insert and check for obstructions. If no obstructions identified, with flow sensor insert removed, turn on a zone and spin the paddle wheel for same duration as tap test.
ii. Turn on any zone. Wait 1 minute. Begin spinning wheel for at least 2 minutes.
iii. Receive from smartlink to see if flow is recorded.
- If no flow, sensor needs to be replaced.
- If flow records, verify proper distances of downstream and upstream straight pipe. If Data Industrial, verify proper depth of flow sensor.
