Density Calculator QML51: Adaptable to Diverse Application Environments Through Various Sensor Options

Endress+Hauser’s Density calculator QML51 enables continuous inline measurement of density, reference density and concentration of liquids as well as media detection using proven vibronic measurement technology. The calculator operates with up to two Liquiphant vibronic sensors with integrated density electronics and compensates for temperature and pressure influences by integrating dedicated sensors. Its modularity makes it ideal for liquid applications in tanks and pipelines across a wide range of industries.


Benefits

  • Real-time inline density data replaces manual sampling and laboratory analysis
  • Proven vibronic technology ensures repeatable measurement results with minimal sensitivity to build-up
  • Modular connectivity with industry-specific Liquiphant vibronic sensors and two additional input channels optionally used for temperature and pressure sensors
  • Fast and guided commissioning via integrated web server with selectable, predefined concentration tables
  • Verification of sensor accuracy provides precise and stable measurement results

Applications

Thanks to industry-specific sensors, density calculator QML51 is suitable for diverse applications:

  • Chemical: Reliable measurement in aggressive media (e.g. concentration in batch reactor)
  • Mining, Minerals & Metals: Robust performance in abrasive media (e.g. lime milk concentration)
  • Food & Beverage: Accurate measurement in hygienic processes (e.g. media detection in soft drink production)
  • Life Sciences: Inline monitoring of media composition

Specifications

  • Measuring Principle: Vibration Liquids
  • Characteristic / Application: Density Computer Software offers modules for density, reference density, concentration of liquids and for intelligent medium detection.
  • Specialities: Configuration via webserver
  • Supply / Communication: 24 VDC
  • Ambient Temperature: -20…60°C (-4…140°F)
  • Communication: Modbus TCP 4-20mA with converter, OPC UA
  • Certificates / Approvals: ATEX, CSA, IECEx, NEPSI with ex barrier
  • Components: Protocol converter Modbus TCP to 4-20mA active barrier RN22

ADVANCED Motion Controls Takes Servo Drives to New Heights (and Depths) with FlexPro Extended Environment Product Line

Advanced Motion Controls is proud to announce the addition of six new CANopen servo drives with Extended Environment capabilities to their FlexPro line. These new drives join AMC’s existing EtherCAT Extended Environment FlexPro drives, making the FlexPro line the go-to solution for motion control applications in harsh environments.

Many motion control applications take place in conditions that are less than ideal, such as extreme temperatures, high and low pressures, shocks and vibrations, and contamination. Electronics, including servo drives, can malfunction or sustain permanent damage in these conditions.
