The TANK ALARM grabs attention with a bright flashing LED and a loud beeper when liquid level is too high or too low. Easy to
install. Easy to adjust the depth in tank. Stop overfilled or empty tanks for good!
Better Tank Level Control...
- Always on duty because it uses uninteruptible battery power. Lasts for years.
- Loud warbling tone cuts through the loudest industrial noise.
- Rugged. Built for rough, wet and corrosive environments.
- A functional check is simple - just loosen the cord grip and lift the Tank Alarm out.
- Reliable float switch is protected inside a pipe.
- Safe. 9 volt circuit in a waterproof enclosure.
- No wetted metal parts.
- Choice of power. Battery, 12VDC, 24VDC or AC power option.
THE TANK LEVEL ALARM prevents overfilling. Easy to install as its battery powered. No wires, no electricians needed. Lithium
battery included lasts for years.
- 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. further discussion.
- Easy to adjust the depth of the Tank Level Alarms - just loosen the nut and slide the level alarm to the correct depth. Adapters
for any mounting situation. (2" NPT, bolt-on flange, bulkhead feedthrough etc.
- Float is protected inside a pipe. This feature protects the level float so it can't be damaged. Screw-on float guard allows
inspection of the float. Optional sreened float guard keeps solids, debris or insects out so they don't foul the float.
- Weatherproof enclosure - NEMA 4X (IP65). High-visiblity beacon LED is clearly visible outdoors.
- Any Depth. Standard level alarm depths available up to 5 ft. Custom depths have been made 20 feet deep.
- Optional circuit board allows different behaviors in addition to testing the circuit such as silencing the buzzer while allowing
the LED to continue flashing, a snooze alarm to silence the buzzer temporarily, shutoff mode for filling tanks so the LED and
buzzer both turn off until the next fill-up, and low battery monitoring. This is the "silencing button" option.
- Different models
- The PVC tank level alarms have a polypropylene float protected in a PVC pipe, and the screen material is
polypropylene. (TH-10)
- Polypropylene models (ex. TH-PP) have all polypropylene parts including piping.
- PVDF (Kynar) models have a reversible float.
- Stainless steel tank level alarms on this page.
- Everything Included - Every unit includes a threaded bushing to adapt the 1" NPT threads for the cord grip to 2" NPT.
