Application:

The Deltabar S differential pressure transmitter are
suitable for:
• Flow measurement (volume or mass flow) in conjunction with primary elements in gase, steam and liquids
• Level, volume or mass measurement in liquids • Differential pressure monitoring, e.g. across filters and pumps
• Corrosive or abrasive applications using unique ceramic sensor technology (PMD70). For example, DP
measurement across a filter with abrasive product
• High temperatures up to 662°F (350°C) with remote diaphragm seals (FMD78)
