Discrete Level Indicators: Switches To Keep Your Operation Afloat

a row of stainless steel floatsYou have liquid in containers, and you need to keep track of the liquid in those containers. You already know that liquid level measurements come in two types: continuous measurements that give on-going feedback about the level of the liquid being measured, and discrete measurements that give, essentially, a Yes or No answer to the question, "Is the liquid at this particular level?" But which technology type is the right one for you? Your liquids don’t require "up-to-the-minute" monitoring, you just need to know when "critical levels" are reached. Congratulations, you need a float switch!

Continuous Level Measurement: Magnets To Float Your Boat

Resistive Chain Level Sensor on Oil TankLet’s be honest with each other. (It’s ok, we’re all friends here, right?) When you think of continuous liquid level measurement, magnetic float level sensors aren’t the first thing you think of. And when you do think of them, your first instinct isn’t “Hey! That’s the perfect sensor technology for this job!”

It’s ok, you’re not alone. The excuses come easy: too much upfront effort to determine the length of the stem; no idea what kind of float to use; more expensive to transport; difficult to store and install. Yeah, we’ve heard them all.

But notice what doesn’t come to mind: maintenance, ease of use, reliability, and durability. That’s because you don’t have to worry about any of these issues with a magnetic float level sensor. They are simple to use, and highly durable, which translates to incredibly low maintenance and long-lasting reliability. Let’s take a closer look.

Liquid Level Sensor Technology Decision Tree

illuminated exclamation mark in a field of dark question marksHere it is, the week after Christmas, and you still haven’t gotten that special something for your process system. A liquid level sensor would be great, but you just aren’t sure what type of sensor would be best for you, uh, your process system.

Well, APG is here to help. No, we didn’t put together a comprehensive gift guide for your process system. But, we did manage to assemble this handy-dandy Liquid Level Sensor Technology Decision Tree. Answering each of these questions will help you identify the liquid level sensor technology that best fits the needs of your system.
