Product Specification

VPFlowScope DP Compressed Air Flow Meters Description
The VPFlowScope DP measures mass flow, temperature and pressure simultaneously and is optimized for wet compressed air measurements. The patented design has a bright blue LCD display which provides real-time information that, in combination with the built-in data logger, enables you to make recordings for certain periods of time. In turn, you can use our VPStudio software to process this data and print reports for real-time measurements.

VPFlowScope DP Compressed Air Flow Meters Features and benefits
• For wet compressed air
• Three sensors in one instrument
• Standard Modbus and 4 … 20 mA
• Bi-directional

VPFlowScope DP Compressed Air Flow Meters Applications
• Air audits
• Compressor efficiency monitoring
• Air treatment equipment (drier/filter) monitoring
