Product overview
The VPFlowScope In-line 3/8" is a flow meter which measures flow rates of air and oxygen in 3-8
inch pipes. The actual flow rate and the total flow will be shown on the display in selectable units.
The Modbus and analog 4..20 mA output enables you to interface with 3rd party monitoring systems.

Quick start
This chapter contains the basic steps to start using your VPFlowScope In-line 3/8" flow meter.
Additional information on all subjects can be found in the next chapters.
1. Unpack
Unpack the box and check if all items are there and in good shape.
2. Apply power
Connect the unit to a DC power source (14 .. 24 VDC).
See chapter 9 Electrical connections
information.
3. Mechanical installation
Find the best point of installation for this product. Make sure that the process conditions are within
the specifications of the flow meter and the upstream and downstream straight pipe lengths are
respected.
For installation of the flow meter, the pipe needs to be cut.
Mount the flow meter between the pipe ends using Hylok SICMC-6-6G.
See chapter 6 Mechanical installation
for more detailed information.
4. Electrical installation
Connect a cable with 5 Pin M8 connector to the flow meter. The cable can be connected to a central
data acquisition / building management system or data logger via Modbus RTU or 4..20 mA.
Apply 14 .. 24 VDC to power up the device. Use a Class II power supply (less than 2 Amps).
See chapter 9 Electrical connections
5. Configuration
No configuration is required for proper measurement. Configure the Modbus address or the 4..20 mA
settings when they are used. These settings can be changed in the menu using the buttons.
Optionally the displayed units can be changed. By default they are set to:
Row 1: flow in ln/m
Row 2: total flow in l
Row 3: temperature in °C
It is possible to switch between 1, 2 or 3 parameters.
