Transcription

1 Technical Information Liquistation CSF22 Automatic stationary sampler for liquid media Integrated multiparameter controller with Modbus RS485 communication Application Liquistation CSF22 is a stationary sampler designed for the fully automated sampling, defined distribution, and temperature-controlled storage of liquid media. The standard product version has one 0/4 to 20 ma analog input, one binary input and one binary output. The sampler is designed for use in the following indoor applications: Municipal and industrial sewage treatment plants Laboratories and Water Conservancy Boards Monitoring of liquid media in industrial processes Your benefits Rugged and reliable: Refrigerator with 304x housing Reliable sample temperature regulation Optimal air circulation in the lower enclosure Simple and easy to use: Swift menu guidance, navigator and large display Bottle tray for easy sample transportation Parts carrying medium are easy to disassemble, making cleaning and maintenance simple Flexible: User friendly programs ranging from simple time programs to event programs Functionality can be extended by connecting different input parameters Communicative: Integrated data logger for recording measured values Service interface for data transmission Modbus RS485 communication Safe: Automatic diagnostic monitoring Optional battery backup system ensures uninterrupted operation in the event of power failure TI00473C/07/EN/

2 Function system design Liquistation CSF22 sampler A complete sampling unit comprises: Liquistation CSF22, with the following depending on the version ordered: Controller with display, soft keys and navigator Peristaltic pump for sampling Plastic (PE) sample bottles for sample preservation Sample compartment temperature control for safe sample storage Suction line with suction strainer or filter Example of a Liquistation CSF22 a Bottle distribution 6 Power supply 2 Distribution arm 7 Peristaltic pump 3 Medium detetection and suction-line connection 8 Door lock 4 Signal connection 9 Refrigerator display 5 Controller 2 Endress+Hauser

3 Mode of operation Sampling steps with a peristaltic pump a Sampling takes place in three steps: 1. Purge/rinse The peristaltic pump runs in reverse and forces liquid back to the sampling point. 2. Intake The peristaltic pump runs forward and draws in liquid. Once the liquid detection system detects the sample, the pump is controlled by the flow and the specified sample volume is calculated automatically. 3. Purge The pump runs in reverse again and forces the liquid 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: Liquid is initially drawn in until the liquid detection system reacts, then the pump switches and forces the liquid back to the sampling point. This process can be repeated a maximum of three times. The sample is then taken as described Pump tubing Pump rollers Liquid detection system (patented) Peristaltic pump a The pump rollers deform the tubing, thereby causing a negative pressure and the suction effect. The liquid 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-calibrating software guarantees that the sample volume remains constant. Endress+Hauser 3

5 Sampling control a. Flow curve b. Time proportional sampling: Constant time constant volume (CTCV) A constant sampling volume is taken at steady intervals. c. Flow proportional sampling: Variable time constant volume (VTCV) A constant sampling volume is taken at variable intervals. d. Flow proportional sampling/time override: Constant time variable volume (CTVV) A variable sampling volume is taken at steady intervals. e. Event-controlled sampling: Sampling is triggered by an event. 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 analog input and binary input in the standard version of the product. Customized text is entered to ensure the correct assignment of the inputs in the memory. a Intake speed with different suction lines ft/s m/s Intake speed in m/s at suction heights in m (vertical lift) 1 Intake speed as per Ö 5893 (Austrian standard) 2 Intake speed as per EN 25667, ISO m ft a Endress+Hauser 5

6 Sample distribution CSF22 offers a range of bottle combinations and distribution versions. The sequencial version can be changed or replaced easily without the need for special tools. In addition, the software makes it possible to configure individual bottles and bottle groups as well as assign them to change based on a programmed event. Note! The composite version can not be upgraded to sequencial. Bottle groups and distribution version depending on the order version: CSF22-**1** CSF22-**2** CSF-**3** 20 liter, PE direct distribution 1 2 liter, PE direct distribution 12 1 liter, PE direct distribution 24 Sample preservation The sample bottles are located in the sample compartment made of stainless steel. All parts that transport liquid can be removed and cleaned easily without the need for additional tools. Sample bottles a Sample temperature regulation The temperature of the sample compartment can be adjusted using the controller. The factory setting is 4 C (39 F). The current temperature is shown on the display. Display of cooling system a Endress+Hauser
