A standard loop with a nominal volume of 100

L is included with the
ME valve. If you need a loop with a different volume, follow the
instructions below to make a loop. To calibrate the new loop, follow the
instructions that start on
page 89 .
To make a standard loop:
1. The table below indicates the tubing length for several standard loop
sizes. These values are approximations because tubing IDs vary.
After checking the table, cut a piece of tubing to the suggested length.
Be very careful to cut the end square to the axis of the tubing, with no
angle. Tubing that is poorly cut will cause fittings to leak.
2. Install a 10-32 PEEK bolt (P/N 043275) and a PEEK ferrule fitting
(P/N 043276) on both ends of the tubing.
To calibrate the standard loop:
1. Install a plug (P/N 042772) in one end of a black coupler
(P/N 042627). Install the coupler on one end of the standard loop.
2. Repeat Step 1 on the other end of the loop.
3. Weigh the loop, on an analytical balance, to the nearest 0.001gram.
Record the weight.
4. Remove the loop from the balance.
5. Remove the plugs from the couplers.
