Grafana alert check difference between value t0 and t-1

Hi !
I would like to know:
Is it possible in grafana to create an alert between the last value and the previous value of a query?
How to configure grafana alert that can do it?

For my project, i will monitoring the fuel level of a tank.
And i want to be alerted when the difference between my last fuel level and the previous level is different of more 10L.

Example 1:
t0: 185
t-1: 188

Okay no alert (difference less than 10L).

Example 2:
t0: 150
t-1: 200

Alerting (difference more than 10L).

Many thanks in advance for your assistance,
and I am looking forward to hearing from you.

Baptiste.
