Function
Please note
The flow cell module VariaSens C (Module name D02) can be used in
combination with membrane sensors for the measurement of free
chlorine, total chlorine, ozone and chlorine dioxide. It must be ensured
that only one of these disinfection agents is present in the water and that
the cross-sensitivity of the sensors is allowed for.
The following section describes the functional principle of the flow cell
module VariaSens C from the sample water inlet to the sample water out
-
let, see Image9 on page24:
Sample water inlet
The sample water supply is connected on the input side via the G1/2”
connection on the ball valve. The input pressure must be around 0.25 to
3.0 bar. To guarantee a constant flow, the minimum input pressure must
not be less than 0.25 bar. If the pressure is lower, an optional booster
pump must be used. If the admission pressure exceeds 3.0 bar, an
optional pressure reducing valve must be used.
Optional strainer
(W3T158721)
The sample water flows over the strainer, which prevents dirt particles
penetrating into the flow cell module.
Check valve housing
In the direction of flow, the sample water flows through the filter unit or
through the installed fine filter (only with membrane sensors) to the check
valve housing. The check valve ensures sample water is only in the
correct direction.
Fine filter
The fine filter is only used in conjunction with membrane sensors.
Multi-sensor
The multi-sensor monitors the correct flow following the float principle
with reed switch and records the temperature with a Pt1000 sensor.
Large-area sample water earth ground is via the stainless steel sensor
housing.
Flow control valve
The flow control valve ensures a flow of the sample water that is not
dependent on the operating pressure. The correct sample water flow of
33 l/h is preset, checked and documented at the factory. If the inlet pres
-
sure increase, the control valve moves to keep the flow constant, if the
inlet pressure drops, the control moves to keep the flow constant.
Cell body
The transparent cell body contains the sensors and the LED glow stick.
The sensors are installed in the location holes in the cell body cover with
standardized threaded connections or in special sensor holders. The
LED glow stick is installed in the cell body cover to visually monitor the
sensors and to signal messages and errors in color.
