Self-Validating Systems

Self-validating ATEX-rated system for exacting on-line applications

The Manalytical ATEX Auto-Zero System provides high precision, on-line moisture analysis in applications where levels of contamination are greater than normal and routine servicing is impractical.

  • A cost-effective methodology to help mitigate the effects of contamination.
  • Reduces the necessity for operator interface and maintenance - 24 hour uninterrupted operation.
  • Extends the mean service interval of the System and reduces maintenance costs.
  • Ideal for Natural Gas and Petrochemical applications. For example: Offshore Platforms, FPSOs, Post-Glycol 'Contactor' Monitoring, LNG, Pipeline Drying, Natural Gas Storage & Distribution, Receiving Terminals (Custody Transfer) and LPG Container Transfer.
  • Customised Auto-Zero & Span Systems are also available. See pictures below.
