# Alert When a Silo Is Nearly Full (https://logable.app/use-cases/silo-nearly-full)

Get an alert when a silo passes ninety percent of its capacity, so you can hold or redirect the next delivery before it overfills.

## Equipment
One silo, filling, with the load cells reporting its weight against the capacity you set.
- **Silo** weight

## The reading
- **Metric:** weight (t)
- **Source:** load cells under the silo legs
- **Cadence:** every minute

## The problem
Cement Silo 1 is at 366 t against a 400 t capacity when the next load arrives. The tanker discharges, material goes over the top, and somebody spends the shift cleaning it up.

## The alert
**Nearly full** (warning)
nearly full
Fires at 90% of this silo's capacity, and clears once it drops back to 80%. That gap is wide enough that a single delivery won't flip the alert straight back off.
Add it from the silo's Triggers tab. It uses the same capacity the stock presets use, so there is no second number to keep in step.

## The response
- **Sent by:** push, email and the in-app inbox
- **Who is told:** the rule's recipients
- **What happens:** The operator holds or redirects the next delivery. The alert names the silo and the weight, so the decision does not need a phone call to the plant.
- **Stops when:** somebody acknowledges

## Frequently asked questions

### How do I get an alert before a silo is overfilled?
Open the silo's Triggers tab, select Browse presets, and add Nearly full. It reads the same capacity the low stock presets read, so nothing extra is configured.

### What level does the silo nearly full alert fire at?
Ninety percent of the capacity you set for that silo, and it clears once the silo drops back to 80 percent. That gap is wide enough that one delivery does not flip the alert straight back off.

### Who gets told when a silo is nearly full, and what stops the reminders?
The rule's recipients, by push, email and the in-app inbox. Acknowledging stops the reminders. If nobody acts, the escalation ladder tells the next person on the list.
