Putting Transmitter into Operation
The following procedure explains how to sequence the valves in your flow measurement piping or
optional bypass manifold to ensure that your transmitter is not over-ranged and that seal liquid is
not lost. Refer to Figure 5 or Figure 6.
NOTE
Procedure assumes that Process shutoff valves are open.
1. Make sure that both upstream and downstream manifold valves are closed.
2. Make sure that bypass valve is open.
3. Slowly open upstream manifold valve.
4. Close bypass valve.
5. Slowly open downstream manifold valve.
Taking the Transmitter Out of Operation
The following procedure explains how to sequence the valves in your flow measurement piping or
optional bypass manifold to ensure that your transmitter is not over-ranged and that seal liquid is
not lost. Refer to Figure 5 or Figure 6.
NOTE
Procedure assumes that Process shutoff valves are open.
1. Close downstream manifold valve.
2. Close upstream manifold valve.
3. Open bypass valve.
4. Carefully open the vent screw to release any residual pressure before disconnecting
lines.

WARNING
When venting pressure from the transmitter, wear suitable protective equipment to
prevent possible injury from process material, temperature, or pressure.
