Mass flow volumetric flow

Mass flow and volumetric flow

Measuring mass flow has clear advantages over measuring volumetric flow. Learn about both measurement principles and how on how to convert one unit into the other.

Mass flow and calculations

There are a few things to take into account when comparing flow meters’ results. In this article read more about the principle of mass flow, what to be careful about and how to calculate with mass flow.

VPFlowScope M with bi-directional option

AN4 Bi-directional flow measurement

The VPFlowScope product line has unique bi-directional measurement capabilities. But when do you use them and what are the benefits? Find out all about it in the application note.

VPFlowScope M with alarms

AN12 Alarm output of VPFlowScope M

The VPFlowScope M features an alarm option for condition monitoring. It can be configured with VPStudio. Upper, lower or a combination of these boundaries can be set as a condition level.

VPFlowScope and Modbus

AN11 Modbus networks

The VPFlowScope product line communicates via RS485 (Modbus RTU). In this application note we cover more detailed information on common Modbus issues and how to get it right.

Pipe measurements

The VPFlowScope M, Probe and DP all measure velocity. To provide output in volume flow like m3n/hr or SCFM, you need to configure the inner pipe diameter into the VPFlowScope.
