7. UFVA
The equipment contains a reference volume, a flow directing valve (UFVA) and
electronics. The UF calibration station controls the directing valve by measuring low
level and high level of the reference volume and depending on the selected UF mode
the valve will become closed or opened when low or high level is detected.
Low Level fill up. The reference is filled just over the first level
transducer.
Low Level drain. The reference is emptied just below the first
Level transducer.
High Level fill up. The reference is filled to just over the second
level transducer.
High level drain. The reference is emptied just below the
second Level transducer.
