Gizmo Engineering started in 1998 when the founder needed a liquid level alarm to monitor chemical drums. At the time, no such product existed, and so he built the world’s first drum level alarm or the ‘Drumalarm”™ liquid level alarm.   It was born in the electroplating industry where everything is continually exposed to acid and caustic mists and splashes. There is still nothing else like it, and nobody who knows more about them.


Over the years we have perfected the family of liquid level alarm systems to survive this environment – and yours. Along the way, we developed many other controls with the same ethos. We have continued to blaze our own path, creating many previously unknown products. What started with a single device has blossomed into an extensive line of products – all of them robust, simple to install and minimum or no maintenance needed. They will help you gain control over your industrial processes from liquid level, to temperature, timing, pH and more. Here is an overview of our products on our line card.

9V battery

We prefer battery power because it’s uninterruptible, safe, and fast and easy to install.  To take advantage of this, we have developed low-power circuits to give years of operation on a single battery.  However we provide line-powered devices too when needed.

Better than it has to be.

  • Everything waterproof.
  • Everything corrosion proof.
  • Float switches protected inside a float guard.
Custom PCB

Unique products to meet previously unmet needs. Where necessary, we develop our own circuits to create some products. The goal is to make products to help to simplify control over your processes.


In addition to selling products through our website, we also have other sales channels such as our distributors, and for select products, e-commerce sites like Amazon.  We are proud of the 5-star feedback ratings we maintain at all of them. We are so confident, we offer a 2 year unconditional guarantee on our products.
