Discover the key differences between point level sensing and continuous level measurement — and how Whitman Controls’ L20, L90, L95, and L96 series help engineers choose the right technology for simple high/low alarms, real-time VFD control, leak detection, and safety-critical redundancy architectures.
Discover how to correctly match sensing technology — differential pressure, capacitance, float, or ultrasonic — to your pressurized tank’s media, crush pressure ratings, and mounting configuration, with a complete installation and safety guide using Whitman Controls’ L20, L40, L96, and Red Seal series instruments.
Discover how specific gravity directly determines float switch performance in low-density liquids like oils and solvents — and how Whitman Controls’ L20, L30, and L95 series are engineered to deliver reliable level detection down to a specific gravity of 0.70, including precise liquid interface detection between two immiscible fluids.
Discover how to match the right float material — Buna-N for petroleum and hydraulic oils, stainless steel for high-pressure and hygienic applications, or polypropylene for chemically aggressive lower-pressure systems — to ensure long-term buoyancy, compatibility, and reliability in your Whitman Controls liquid level switch.
Introduction This is a fun one, so we’ll get right into it. In early 2025, a design/build mechanical
There are many different ways to monitor liquid levels in industrial processes, each generally designed to serve a certain band of applications within specific industries. Only a few technologies might be considered to apply universally across most types of projects, with the best example of this being hydrostatic level measurement. In practically all process, manufacturing, agricultural, and utility facilities we’ve visited, there’s always at least one hydrostatic level sensor found somewhere on the property. In our opinion, hydrostatic level sensors are so popular due to their very attractive combination of high accuracy, simple sensing technology, competitive costs, and long-term stability. If you haven’t met hydrostatic level sensors before, let’s introduce you!
