Installation with standard safety line
Step 1.
1. Keep the ball valve closed!
2. Insert the compression fitting in ball valve. Use
Teflon tape or liquid sealant.
Step 2.
1. Insert the VPFlowScope probe until it hits the
ball valve. The probe remains in the compression
fitting.
2. Attach the safety line to the pipe.
3. Hook the safety line to the ring of the
VPFlowScope probe. Make sure that the line is
tight.
Step 3.
1. Keep your hand on top of the VPFlowScope
probe.
When you install the VPFlowScope
probe into a pressurized system you are about
to experience temporary leakage and force trying
to push out the VPFlowScope probe from the
compression fitting. When the safety system is
correctly installed this is part of the normal
installation procedure.
2. Open the ball valve slowly and push the
VPFlowScope probe gently downwards.
3. The probe tip should be in the center of the
pipe
4. Tighten the compression fitting
Step 4.
Optionally pull tight the safety line. When
adjusting the safety line, make sure you secure
the VPFlowScope otherwise during adjustment.
This can fox example be done by applying force
by hand on top of the instruments or with a
secondary safety line
1. Unlock the safety line
2. Pull tight the safety line and lock the safety
line again
3. Align the flow direction. Alignment by the eye
is sufficient
