The CELLULAR DIALER circuit board mounted inside a Tank Alarm or Drum Alarm, will send a text message (or SMS) when there is a high or low liquid level state. The cellular dialer monitors liquid level round-the-clock and transmits anywhere there is cell phone coverage using the GSM network.
No power cord
The cellular dialer is battery powered. Lithium battery power lasts for 3 years. Battery power is uninteruptible, can't be unplugged, is unaffected by power failures, and never needs to be reset, Replacement batteries available at any Radio Shack. If preferred however, AC power is an option.
Other features:
- No installation: the cellular dialer is shipped already installed in the tank alarm and ready to work as soon as power is connected. No boot-up, startup, passcodes, mysterious modes, calibration, or registration.
- Weekly status call-in to let you know the electronics are OK.
- Test button on Tank Alarm to place a call on demand.
- No external antenna to get damaged or mis-positioned.
Operation
When there is a level alarm condition, the cellular dialer transmits a text message within 1 minute. It then goes to sleep mode to conserve power.

The battery voltage is constantly monitored, and in the case of low battery voltage, a different text message is sent every 12 hours you know to replace the battery.
