Liquiport benefits
Simple and user-friendly menu-guided operation with "Quick-Setup" for rapid commissioning. This unit has one User Mode Standard, up to 8 are optional. A User mode is a preprogrammed location or configuration.
Four main programs are available.
A program can be triggered due to the following criteria:
Time The sample is taken after a preset time.
Quantity The sample is taken after a predetermined measured flow quantity.
Ext. signal The sample is taken when an external signal is active on a digital input.
Flow The sample is taken after a preset time. The sample taken is always proportional to the measured flow rate.
Several criteria can be defined at a time. There is an OR connection among the defined criteria. In other words, once a switching criterion is met, the assigned switching program is executed.
Sampler compartment can be sealed locked and carried separately for easy and safe sample transportation.
Communicative Data Management and RS232 interface for configuring and for data transmission.
Internal Data Logger
The Liquiport 2000 sampler has an internal data logger in which the following measured values can be stored:
Analogue signal (example: flow signal)
Sampling protocol (sample volume, bottle filling times, results).
As an option, the Liquiport has an additional RS232 connection socket for a multi-parameter probe.
The following multiparameter probes can be connected to this connection socket, MultiSens C600, YSI 600R, YSI 600 XL, YSI 600 XLM, YSI 6920, YSI 6820, YSI 6600. The minimum scan rate of the internal data logger is 1 second for the analogue signal and 1 minute for the multi-parameter probe measurements. The contents of the internal data logger can be read out to a PC using
Liquid Handling and Medium Detection System
The medium detection system controls the electronic volume calculation. The medium detection system has a maintenance free ceramic membrane pressure sensor at the heart of the system. The pressure sensor detects the difference between a full and empty pump tube.
The advantages - Intelligent: the suction height is automatically detected and does not have to be configured. Sampling takes place in three steps. Rinsing the suction line: the sampling liquid is sucked in until the medium detection system is triggered. Then the pump runs backwards and pushes the liquid back to the sampling point. The rinsing process can be repeated up to three times. Sucking the sampling liquid: the sampling liquid is sucked from the sampling point to the sampler and the sample volume is calculated electronically. Emptying the suction line: after sampling, the liquid left over in the suction line is pumped back to the sampling point.
You can easily calibrate the sample volume and a three lobe peristaltic pump offers the maximum lift possible.
