When looking for the right measuring technology and the right product we basically divide measuring levels into three types of tasks:
- Is it continuous measurement or knowing when a limit is reached ?
- Measuring solids or liquids ?
- Contact-free measurement or in contact with the product ?
- Frequency sweep: The clever alternative to oscillating forks and the new way of monitoring levels
- Potentiometric: Level transmitters precisely measure homogeneous fluids
- Hydrostatic: Sensors measure filling levels, water columns and surface levels by measuring pressure gradients
- Ultrasonic: Contact-free measurement of any materials - reliable from a few centimeters to a few meters
- Capacitive: This technology penetrates non-conductive materials and so can detect what is behind non-metallic enclosures
- Conductive: Level switches detect conductive fluids rapidly, reliably and accurately


Gizmo Engineering creates unique, durable liquid level controls meant to simplify liquid level and timing. These solutions were developed in the electroplating industry where everything is continually exposed to acid and caustic mists and splashes.
Gizmo solutions utilize battery power extensively because its uninterruptible and faster to install. Low-power circuits give years of operation on a single battery.
Products include Tank, Drum and IBC alarms, Intrinsically Safe level controllers, alarm boxes, timers and power failure alarms
- Teflon float switches because they’re impervious to most chemicals.
- Float switches protected inside a “float guard”.
- Waterproof.
