WARNING!
Sensor run-in periods
This can result in hazardous incorrect metering.
– Correct measuring and metering is only pos‐
sible if the sensor is working perfectly
– Observe the sensor operating instructions
– Calibrate the sensor after commissioning
WARNING!
Danger from hazardous substances!
Possible consequence: Fatal or very serious inju‐
ries.
Please ensure when handling hazardous sub‐
stances that you have read the latest safety data
sheets provided by the manufacture of the haz‐
ardous substance. The actions required are
described in the safety data sheet. Check the
safety data sheet regularly and replace, if neces‐
sary, as the hazard potential of a substance can be
re-evaluated at any time based on new findings.
The system operator is responsible for ensuring
that these safety data sheets are available and that
they are kept up to date, as well as for producing
an associated hazard assessment for the worksta‐
tions affected.
CAUTION!
– The sampling tap must be closed, otherwise
sample water can escape.
– The sample water should be free from air bub‐
bles to ensure reliable measurement and con‐
trol. Should the sample water carry air with it
as a result of the process, then suitable means
must be used to separate out the air.
– Please also observe the operating instructions
for controllers and fittings and any other units,
such as sensors, sample water pumps ...
Maximum permissible operating pressure: 1 bar at maximum 45 °C

1. Tighten all threaded connectors and check that the threaded
connectors are leak-tight.
2. Check the positions of all shut-off valves. The position of the
shut-off valves has to guarantee that the
DULCOTROL ® measuring/control station is tight and that
there is a flow of sample water.
