New differential pressure meter with remote data transmission

Media 7 von SAMSON
|   Produits

The Media 7 is suitable for liquids, gases and vapors, in particular for cryogenic gases, such as argon, oxygen and nitrogen.

The operating modes are adjustable as required:

  • Filling level measurement (with operating pressure) in stationary pressure vessels and transportation vehicles
  • Differential pressure measurement between flow and return flow pipe as well as pressure drop measurement across valves and filters

Special features

  • Microprocessor-controlled transmitter with digital interface
  • Modular design: simple to install or exchange optional additional functions by inserting option modules (four slots in the device)
  • Cabled data transmission or optional remote data transmission over the integrated GSM module
  • Measuring ranges between 0 to 160 mbar and 0 to 3600 mbar
  • Nominal pressure PN 60
  • Internal absolute pressure sensor
  • Modular power supply unit with standby power supply (SPS)
  • 4” backlit graphics display
  • Configuration and programming using the TROVIS-VIEW software
  • Easy operation using capacitive keys
  • Start-up wizard
  • Volume and mass measurements in any type of vessel using a calculation or a freely programmable characteristic
  • Zero and span adjustment activated by key without influencing each other

Media 7 logs all the monitored parameters continuously and transfers them to SAM TANK MANAGEMENT. As a result, an extensive source of data is provided for further analysis. These analyses offer considerable advantages and help save costs. Advantages include:

    • Improvement of delivery scheduling and routes
    • Creation of cost-efficient delivery plans
    • Better utilization of truck capacities
    • Analysis of tank farm sizing
    • Monitoring of maximum filling and avoidance of product loss
    • Monitoring of pressures and analysis of vacuum insulation
    • Avoidance of unnecessary costs incurred due to empty tanks
    • Monitoring of plant states, e.g. overloading of vaporizers
    • Immediate notification in the event of device malfunctions
    • Effective maintenance planning
