LIA 027
Instrument loop (local)
LIA 085
Instrument loop (located in central room)
LCV
Level control valve
Output signal
0.2 to 1.0 bar
Taper threads
Connect steel fittings together/ connect compression fitting to them
Parallel threads
Used on compression fittings to connect copper to copper
PTFE Tape
Used to achive an air tight seal on threads
Olive
Creates a seal on copper pipe using compression fitting. Never use PTFE tape to cure a leak.
Compression nut name
Wade couplings
PVC covered pipe use
Protects the pipe from general ware and tare from the environment.
Steel fittings use
Elbow(corner part), other connects up to 3 pipes together
Absolute scale
Uses a vacuum as it’s zero reference point
Gauge scale
Takes into account the atmospheric pressure as it’s a zero reference point
Process variables
Temperature, level
U tube calibration
Put a known pressure on it and see if it reads the same pressure
Calibration error
The difference between the measured value and what your actually putting in
Manometer range
The max amount of pressure before the liquid in the u tube comes out
Process lags
Distance, speed
.
