Endress and Hauser has announced its line of water sampling solutions for monitoring influent and effluent at water/wastewater treatment plants and in industrial process water applications.
Other applications include municipal, industrial and surface water sampling.
The product line includes the Liquistation CSF48 stationary unit and the Liquiport CSP44 portable unit.
The units accept 'hot plug and play' inputs from up to two Endress and Hauser Memosens digital sensors to measure parameters such as nitrates, conductivity, oxygen, pH, ORP, turbidity or suspended solids.
The same unit can be used to simultaneously measure multiple parameters just by changing sensor types.
Each sensor simply plugs into a unit and can be configured from the multilingual display using PC-like menus.
Each unit can store up to 100 programs and can run up to 24 programs at a time.
In addition to the two Memosens digital sensor inputs, base units come with two analogue inputs, two binary inputs, two binary outputs, backlit display, SD card and a CDI-interface.
The stationary unit can be supplied with 17 different bottle configurations, and the portable unit can be supplied with six different bottle configurations.
A base unit can be updated by the user in the field into a complete monitoring and sampling station.
Typical analogue inputs could be from a flowmeter, a rain gauge or any other measuring device with an analogue output.
Typical binary inputs could be pulses from a flowmeter where each pulse represents a certain volume.
For the stationary unit, options also include a choice of interchangeable sample pumping technologies: vacuum or peristaltic.
The portable unit is only available with a peristaltic pump.
The pumps are simple to maintain and require no tools for routine maintenance.
The peristaltic pump meets the EPA's recommended linear velocity of 2ft/s (0.6m/s) at up to 26.3ft (8m) head height.
The sample volume can be adjusted from 10-9,999ml.
Sampling can be programmed to occur based on time, flow or flow-paced time override.
The suction line can be rinsed up to three times.
Options are available for sampling from pressurised pipes.
Sample bottles are kept in temperature-controlled storage in a two-door housing for reliable temperature regulation.
Dual-bottle trays make it easy to retrieve, replace and transport samples to the lab.
Bottles are available in sizes from 1 litre to 30 litres, in plastic or glass.
All parts that transport liquid including the distribution arm, the dosing system and the distribution plate can be removed and cleaned without the need for additional tools.
The UL/CSA/CE-approved 24VDC power supply is standard; battery back-up is optional.
The compact cooling system provides cooling efficiency to reach EPA-recommended storage temperature of 4C (39F).
Sample temperature can also be monitored.
The modular cooling unit is easy to access due to its mounting location above the sample storage compartment.
Multiple housing materials are available to meet the requirements of demanding applications, while the cost-effective materials are used for standard applications.
