1 Sampling steps with a peristaltic pump
Sampling takes place in three steps:
1. Rinse
The peristaltic pump runs in reverse and forces medium back to the sampling point.
2. Intake
The peristaltic pump runs forward and draws in medium. If the medium detection system
detects the sample, the pump is controlled by the flow and the specified sample volume is
calculated automatically.
3. Drain
The pump runs in reverse again and forces the medium back to the sampling point.
One advantage this system offers for obtaining a representative sample is the possibility of rinsing
the suction line several times: Medium is initially drawn in until the medium detection system reacts,
then the pump switches and forces the medium back to the sampling point. This process can be
repeated a maximum of three times. The sample is then taken as described.

3 Pump rollers
4 Medium detection system (patented)
The pump rollers deform the hose, thereby causing a negative pressure and the suction effect. The
medium detection system is based on a pressure sensor which detects the difference between a pipe
that is filled and not filled. Thanks to a patented process for automatically detecting the suction
height, the user does not have to enter the suction height or suction line length. The self-learning
software guarantees that the sample volume remains constant. An optional safety switch integrated
in the pump housing immediately switches off the pump when the pump is opened (recommended if
third-party staff are performing maintenance work).

Sample distribution
Sample preservation
The Liquiport 2010 CSP44 allows flexible configuration of the sample distribution. Users can define
individual bottles and bottle groups as they wish for the main, switchover and event programs.
A distribution arm transfers the sample liquid into the individual bottles. in addition to a 20-liter
composite container made of PE, there are different bottle distributions available. The distribution
versions can be replaced easily and without the need for tools.
The sample bottles are located in the sample compartment. This is fitted with a seamless plastic dish
to ensure easy cleaning. All parts that transport medium (distribution arm, dosing system...) can be
removed and cleaned easily without the need for tools.

a. Flow curve
b. Time-proportional sampling (CTCV)
A constant sample volume (e.g. 50 ml) is taken
at regular intervals (e.g. every 5 minutes).
c. Volume-proportional sampling (VTCV)
A constant sample volume is taken at variable
intervals (depending on the inflow volume).
Time override can be enabled in an
advanced program. This allows long,
flow-controlled sample intervals to be
interrupted if the flow rate is low. A
time-controlled sample is collected.
d. Flow-proportional sampling (CTVV)
A variable sample volume (the sample volume
depends on the flow rate) is taken at regular
intervals (e.g. every 10 min).
Only in version with peristaltic pump.
e. Event-controlled sampling
Sampling is triggered by an event (e.g. pH limit
value). Sampling can be time-paced, volumepaced or flow-paced, or single samples can be
taken.
Intake speed with different suction lines
Single and multiple samples can also be grouped in a program in addition to the sampling methods
listed. Furthermore, the software allows interval sampling, switchover and event functions. The
latter permit up to 24 subprograms to be active simultaneously for a variety of applications. A
sampling table makes it possible for users to program the bottle assignment, time interval and
sample volume. Signals for external control can be connected via 2 analog inputs and 2 binary inputs
in the standard version of the product. Customized text is entered to ensure the correct assignment
of the inputs in the memory.

Sampler housing
Pay attention to the installation conditions in the "Installation" section and the information on the
materials of the different housing types in the "Mechanical construction" section.
NOTICE
The plastic material polystyrene VO can discolor if exposed directly to sunlight.
In the case of stainless steel housings, the frame around the window can discolor if exposed directly
to sunlight.
The plastic material ASA+PC V0 is recommended for outdoor installations where a sun guard is
‣
not used. The discoloring does not affect the function and operation of the device.

Dependability
MEMO SENS
Liquiport CSP44
Reliability
Memosens technology
Memosens makes your measuring point safer and more reliable:
• Non-contact, digital signal transmission enables optimum galvanic isolation
• No contact corrosion
• Completely watertight
• Laboratory sensor calibration possible, thus increasing measured value availability
• Predictive maintenance thanks to recording of sensor data, e.g.:
• Total hours of operation
• Hours of operation with very high or very low measured values
• Hours of operation at high temperatures
• Number of steam sterilizations
• Sensor condition
A0024356
Sensor check system (SCS)
The sensor check system (SCS) monitors the high impedance of the pH glass. An alarm is triggered if
a minimum impedance value is undershot or a maximum impedance is exceeded.
• Glass breakage is the main reason for a drop in high impedance values.
• The causes of increasing impedance values are:
• Dry sensor
• Worn pH glass membrane
Process check system (PCS)
The process check system (PCS) checks the measuring signal for stagnation. An alarm is triggered if
the measuring signal does not change over a certain period (several measured values).
The main causes of stagnating measured values are:
• Sensor fouled or outside the medium
• Sensor defective
• Process error (e.g. through control system)
Sensor condition check (SCC)
This function monitors the electrode condition and the degree of electrode aging. The status is
indicated by the messages "SCC electrode condition bad" or "SCC electrode condition OK". The
electrode condition is updated after every calibration.
Maintainability
Modular design
The modular sampler can be easily adapted to suit your needs:
Retrofit extension modules for new or extended range of functions, e.g. current outputs and relays
Memory
• Independent, integrated ring memories (FIFO) or stack memories for recording:
• An analog value (e.g. flow, pH value, conductivity)
• Events (e.g. power failure)
• Sample statistics (e.g. sampling volume, filling times, bottle assignment)
• Program memory: max. 100 programs
• Data logbooks:
• Adjustable scan time: 1 to 3600 s (1 h)
• Max. 8 data logbooks
• 150,000 entries per logbook
• Graphic display (load curves) or numerical list
• Calibration logbook: max. 75 entries
• Hardware logbook:
• Hardware configuration and modifications
• Max. 125 entries

Mathematical functions (virtual process values)
In addition to "real" process values, which are provided by connected physical sensors or analog
inputs, mathematical functions can be used to calculate a maximum of 6 "virtual" process values.
The "virtual" process values can be:
• Output via a current output or a fieldbus
• Used as a regulating control variable
• Assigned as a measured variable to a limit contactor
• Used as a measured variable to trigger cleaning
• Displayed in user-defined measuring menus
The following mathematical functions are possible:
• Calculation of pH from two conductivity values according to VGB Standard 405, e.g. in boiler
feedwater
• Difference between two measured values from different sources, e.g. to monitor membranes
• Differential conductivity, e.g. to monitor the efficiency of ion exchangers
• Degassed conductivity, e.g. for process controls in power plants
• Redundancy to monitor two or three redundant sensors
• rH calculation from the measured values of a pH and an ORP sensor
