The sensor measures the density of liquids during the process itself – no need to go to the laboratory. Thanks to a sub-millimeter measuring channel, the properties and quality of a liquid can be precisely monitored even in confined spaces.

Application examples:

• Determination of the mass of liquids: If the density is measured in addition to volumetric flow measurement in orifices, turbines or displacement devices, the mass can be calculated from it.
• Monitoring and control of the quality of fuel mixtures such as E10 or biodiesel.

The DLO-M2_ex sensor for use in hazardous areas according to ATEX: II1G and IECEx: Zone 0 measures the density of liquids and gases in a microelectromechanical system (MEMS system). Thanks to the measurement in the MEMS system, the sensor is only 30 x 83 x 15 mm³ small and can be installed even in tight spaces. The high-precision measurement results are immediately available, allowing continuous measurement during the running process.

Application examples:

• As a supplement to volumetric measurement during aircraft refuelling.
• Monitoring of the delivered and received density of the fuel in tank trucks.
• Concentration measurement of methane/carbon dioxide mixture in biogas production..

Monitor gases and gas mixtures during the process in the smallest of spaces and with minimal quantities of the medium. The sensor not only measures density, but also temperature and pressure – for precise monitoring of product quality and as a basis for determining the concentration of binary gas mixtures.

Application examples:

• Monitoring of welding gas mixtures: To ensure a reliable weld seam, the gases must be mixed in the correct ratio. Gas density data can be used to monitor the gas mixture.
• Monitoring of gas mixtures for food packaging: Density data can be used to monitor the gas mixture for salad or meat packages. This replaces spot checks and reduces losses.
• Testing of clean gases: Gas cylinders can get mixed up. Density data shows whether the correct gas cylinder is in use.

The VLO-M2_ex sensor for use in hazardous areas according to ATEX: II1G and IECEx: Zone 0 measures the density and viscosity of liquids in a microelectromechanical system (MEMS system). Within the MEMS system, the liquid is directed to an omega-shaped microchannel, the so-called omega chip. This tiny silicon tube – it is hardly thicker than a hair – is set into oscillation for the measurement. The density of the medium can be derived from the natural frequency of this oscillation: the denser the medium, the lower the oscillation.

Application examples:

• As a supplement to volumetric measurement during aircraft refuelling.
• Monitoring of the delivered and received density of the fuel in tank trucks.

The FLT-M1 flow sensor has been designed to determine the mass flow of liquids and gases. This is done with a mini Coriolis measuring system with an S-shaped measuring tube and a temperature sensor.

The flow sensor is installed directly in a flow pipe via a manufacturer-specific connection. If medium flows through the flow sensor, the measured value information is generated with the aid of Coriolis forces. The measured values are fed to the higher-level system via a Modbus TTL.

Application examples:

• Quality improvement: High-precision monitoring/dosing of the components
• Optimizing the use of resources
