About Gizmo Engineering

Gizmo Engineering creates durable alarms and controls to simplify control of industrial processes. 

In 1998, an our founder needed a way to monitor chemical level in drums. Since no product existed, he built the world’s first drum level alarm.  It was born in the electroplating industry where everything is continually exposed to acid and caustic mists and splashes. Over the years we have perfected the family of liquid level alarms 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 generally no maintenance needed. They will help you gain control over your industrial processes from liquid level, to temperature, timing, and beyond.

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.  Low-power circuits give years of operation on a single battery.  However we provide line-powered devices too.

Better than it is has to be…

  • Everything waterproof.
  • 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.
