Begin from measuring mode
As the line is drained and prior to steam cleaning, density reading will fall below 0.5g/cm3.
When this happens the converter will read zero flow and no more pulses will be sent from the
pulse output. The current output registering temperature will function as normal. When the line
is refilled and density exceeds 0.6g/cm3, measurement will restart.
When this function becomes active then the standby indicator on the display becomes lit. All
displays for mass flow, density, temperature etc. work as normal. However, if functions 1 or 2
above are selected then the mass flow (and hence volume flow) will be zero and will be
displayed as shown below.

STANDBY.
5.11 Standby function (Fct. 1.1.4. and 3.1.4.)
The instrument may be switched to a 'STANDBY' state. Once in this state, all outputs go to their
off state and the mass totaliser is frozen. The main display will have the STANDBY indicator set
and will display either the frozen totaliser or just STANDBY.

Input maximum density of 5.0g/cm3.
This value is set high as only low fluid
density are of interest in this case.
NOTE : The max. value in this case will set a
hysteresis of 0.1g/cm3
