DP Flow Meters

The Siemens SITRANS P320 is the first differential pressure transmitter on the market to feature remote safety handling. The instruments’ remote safety handling via SIMATIC PDM saves time during SIL commissioning: rather than manually attending to each individual device across a facility.

Benefits

• • Reduced commissioning time due to remote safety handling
  • Suitable for harsh conditions due to robust materials
  • User-friendly due to a clear and large display and diagnostic icons acc. to NAMUR NE107 and a quick start wizard
  • Maintenance cost reduction due to proof test interval up to 15 years
  • Fast reaction and optimized processes due to reduced response time
