RANSMITTERS
There are five transmitters in the T
RIFECTA
system. Two of the transmitters are measuring
differential pressure of each of the Laser-Cyls. This is to provide a measure of liquid level. The
other three transmitters are pressure transmitters. The five transmitters are used to provide
pressure and liquid level information to the PLC for controlling purposes. T

ALVES
The system has many line relief valves. These relief valves protect against the accidental
closing of two valves with trapped liquid between them. The line relief valves are installed on
“candy-canes” to help keep the valve at warmer temperatures. T
