Installation
Flowtube Resistance
1. Check the following loops with power off and wires disconnected.
Record the readings in the open position of the table.
2. Check with the flowtube filled with a process fluid. Use the initial
reading because the value will increase with time.
If performing these checks and making any necessary adjustments to
your system does not solve the problem, or for specific instructions on
making these adjustments, see Table 5-1 on page 5-2 and Table 5-2 on
page 5-3 or contact your Rosemount service representative.
