EMail Alerts


If you enable email alerts you will be notified for about the following conditions:

  1. If a valve changes state

  2. If there has not been valve change state for a period of time

  3. If there is a Hi, Low, or Expired alarm flagged by the unit


Alerts will be sent no more often than once per minute. If multiple events occur from the time that an email is first scheduled, all of the events will be listed in the email. A typical alert might look like the following example:

The level data can be optionally inserted into the data stream during a run when ever the unit is polled. The data record format is:
