- +9
- Entry-level models with 1 kg/m³ accuracy
- Excellent price-performance ratio
- All-in-one instrument in a compact design
- Works even for aggressive liquids
The L-Dens inline density meters are more than just state-of-the-art measuring instruments – they’re the result of over 40 years of practical experience in process density measurement. The L-Dens 7000 series combines high accuracy and a compact design, making it the first choice for precise density and concentration measurements. Thanks to the modular system and the wide range of integration options, these instruments can be easily integrated into measurement systems or production equipment.
The L-Dens 3300 inline density meters are budget-friendly entry-level models. The instruments are designed as a stand-alone unit, so there are no additional costs.
Key features
Accurate and reliable even under changing process conditions
- Get highly accurate density and concentration measurements with a compact design
- Use the most powerful inline density meter series in its class
- Ensure high product quality, optimize energy and raw material consumption, and maximize production capacity
Inline density meters, optimized for every industry
- Use the instruments, which are built with different oscillator materials, to measure non-corrosive and aggressive liquids, even in hazardous environments
- Meet the requirements of a wide variety of applications in virtually all industries, including the chemical, beverage, petroleum, pharmaceutical, and ethanol industries
Maintenance-free, minimal integration costs
- Use inline density meters that don’t need maintenance or consumables
- Adapt the modular instruments to your respective installation requirements, and keep your integration costs low
- Access a range of Anton Paar accessories for inline, bypass, or tank installation
- Benefit from small pumps that have been integrated into the instrument. These are controlled by the density meter, which means extremely fluctuating flow rates – or tank installation – pose no problem
- Use these integrated pumps in hazardous areas with our new Inline Pump 300 Ex d
Easy to commission, easy to operate
- Connect the inline density meters to the powerful mPDS 5 evaluation unit or combine them with the smart transmitter Pico 3000
- Access a variety of communication protocols depending on your requirements
- Get started quickly: instruments arrive factory-adjusted and preconfigured so you get correct instrument settings and application formulas from the get-go
Comprehensive application know-how
- Rely on our comprehensive database to help you best measure the concentration of your liquid
- Draw on our industry expertise:
- If your application isn’t in our database, we’ll develop a formula just for you
- We’ll suggest the measuring method (density, sound velocity, or refractive index) that’s most suitable for your concentration measurement
L-Dens 3300: An entry-level model for all industries
- Get 3-digit accuracy at an excellent price-performance ratio with these inline density meters
- Stay flexible with integrated applications
- Measure non-corrosive liquids, like cleaning fluids, as well as aggressive liquids, such as sulfuric acid, with a stainless steel or glass oscillator
- Use the L-Dens 3300 in every industry
