TANK LEVEL ALARM…

prevents overfilling by sounding an alarm when liquid level changes triggers the float switch.  These level alarms are very easy to install – after you snap in the  battery, just mount it on your tank.  No cumbersome wiring needed.

WHY ITS BETTER

Uninterruptible battery power works through power failures, can’t come unplugged, or be defeated. And, because the Tank Alarms don’t use any power until alarming, the batteries last for years.  Here’s a discussion about batteries.  Nevertheless, for those situations that need it, we also offer wired liquid level alarms.

The depth of the Tank Level Alarms is easy to adjust just by loosening the compression fitting by hand, and then sliding the level alarm to the preferred depth. 

Float switch is protected inside a float guard. The float guard protects the float from all physical damage from shipping, to installation. When necessary it can be unscrewed by hand to allow inspection of the float.  For tanks containing solids or debris, we offer a version of the float guard that has a screen to keep out the debris.  Both of these are unique innovations of Gizmo Engineering.

Rugged weatherproof enclosure is made from PVC and is rated IP65. (NEMA4X)  Suitable for outdoor service. High-visibility beacon LED is clearly visible in daylight.  The buzzer produces a volume of 103dB at 2ft.  This volume is comparable to a smoke alarm. Furthermore, the buzzer tone is a warbling tone which makes the apparent volume even more noticeable. This alarm will be noticed!

The push button is a convenient way to test the alarm when its not actively alarming. However if the unit is in an alarm state, the pushbutton silences the alarm. 

Different operating modes are built-in to suit your needs. Here is a list of the modes available:

• In the default mode, the LED to continues to flash after the push button is pressed to silence the buzzer.  If the alarm condition still exists after 30 minutes, the buzzer sounds again until silenced.  We call this the “snooze alarm” mode.
• If preferred, the snooze alarm feature can be disabled. In this mode, pressing the button will silence the buzzer until the next alarm condition. Meanwhile the LED continues to flash.
• Lastly, in the “tank-filling” mode, the pushbutton turns off the LED and buzzer until the next high level event. (the tank alarm resets itself automatically) This is useful when a bulk tank is being filled by a tank truck; the driver wants to know when the tank is full and then shuts off the alarm. No need to have the beacon LED flashing after that.

Available in any Depth. We use the term “working depth” to mean the depth of the pipe actually inside your tank. More info and diagram here. Generally the tank alarms are available in 10 inch increments, even as long as 20 feet!  However we only keep stock of units up to 60″.  The working depth is added as a suffix onto the part numbers.  For example, the polypropylene model T-PF-10 has a working depth of 10 inches.

High level alarm and low level alarm in the same unit. To switch between orientation, just reverse the float switch. (no tools required)
