A complete measuring system consists of:
1.
Code for
top mounted
models (each unit can be factory calibrated when specifi
c level differentials are specified separately
– specify actuating level(s) for either rising or falling level and operating S.G.)
2. Code for
modifi
ed
models or adders: put an "X" in front of the closest matching order code and specify the modifi
