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.
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.
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.
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.
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.
Guideline installation distance
It’s very important to select the right installation point for your flowmeter. A symmetric, fully developed turbulent flow profile is what is needed for accurate flow measurement.
