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

Klinger Used throughout North America in a vast range of industries, the Davis / Klinger Magnetic Level Gauge is particularly suited to applications where hazardous liquids or gases are in use. All of these instruments are made to order and our engineers will provide expert guidance on the design and manufacture of the Magnetic Level Gauges for specific applications. Davis Magnetic Level Gauges provide immediate and accurate response to level changes, giving clear and sharp legibility over the full range of the liquid level. Local and remote display and point switching are available. Robust, shockproof and completely sealed for safety. Magnetic Level Gauges are particularly suited for dangerous or toxic fluids. Ideal for liquid interface applications with a powerful omni-directional magnet system contained within a non-pressured float design.

A leading manufacturer in the field of industrial sensor and automation technology. Their innovative product range includes the entire measuring chain from sensors to automation solutions for temperature, pressure, liquid analysis, flow rate, filling level, and humidity.

• MAERA S26 Level probes for continuous level measurement in liquids using a Piezoresistive silicon sensor.
• Offering high overload resistance which is particularly stable in the long term, dependable, and temperature resistant. The level probes are manufactured entirely from stainless steel and are resistant to a large range of mediums. Ideal for level measurement in storage tanks or reservoirs, drinking water applications, gray water recycling and tanks containing diesel/heating oil.

If the fluid level in your equipment is critical to its operation or output, you need a company with years of expertise in liquid level sensing design.

Liquid level sensors and switches provide high-reliability monitoring and detection of a wide range of fluid media. Requirements can range anywhere from the sensing of cooking oil, to hydraulic fluids, to diesel fuel tanks (gas level indicator), to water and wastewater, to biohazards, to even deionized or potable water. To effectively address such a wide variety of measurement challenges, Gems offers a broad range of contact, non-contact and non-intrusive liquid level sensors and switches. These are available in multiple technology types, including:

• Magnetic reed switch-based floats - Conductivity
• Solid-state electro-optical - Capacitive
• Ultrasonic - Piezo-resonant

Multiple liquid level sensing technologies may also be incorporated within a single application.
