Automated Propane Tank Monitor Low-Level Alerts

Every hour, WebRun checks tank-monitor readings in ADD Systems for any customer tank that has fallen to or below your low-level threshold, logs the event to a Google Sheet, and posts an immediate dispatch alert in Slack so a delivery run can be scheduled before the customer runs out.

In short

How do I get automatic alerts when a monitored propane tank runs low?

WebRun checks tank-monitor readings in ADD Systems every hour and alerts your dispatch team in Slack the moment any customer tank falls to or below your low-level threshold. Each event is logged to Google Sheets, and tanks with under 3 days of estimated supply are flagged as urgent so emergency deliveries can be scheduled immediately.

  • Dispatch teams are alerted within an hour of any tank crossing the low-level threshold
  • Run-out risk is flagged before customers notice a problem
  • Every low-level event is logged automatically for compliance and operations review

Built for propane delivery companies · heating fuel dispatchers · fuel oil dealers with tank monitors · remote monitoring operations teams

Questions, answered

Does it alert the same tank multiple times if it stays low?

It compares new readings to the previous run's log in Google Sheets and only alerts on first detection or when a tank drops to a new lower threshold, avoiding repeated noise for the same event.

What threshold triggers the alert?

WebRun uses the low-level threshold configured in your ADD Systems tank-monitor settings, typically 20 to 25 percent. You can adjust the threshold in ADD Systems and the run will respect the updated value immediately.

Can it prioritize tanks that are critically low over ones that just crossed the threshold?

Yes. Tanks estimated to have under 3 days of supply are flagged as urgent in the Slack alert and sorted to the top of the list so dispatchers can schedule an emergency delivery first.
