McLane Water Transfer Systems are designed to collect particulate matter, in-situ, in support of oceanographic research projects and environmental monitoring programs. The Phytoplankton Samplers (WTS 6-24-47FH and WTS 6-24-142FH) draw ambient water through filters on which suspended material is collected. Each PPS can collect up to 24 samples, autonomously following a user defined sampling schedule.

• WTS 6-24-142FH (Phytoplankton Sampler with 142mm filters)

The WTS 6-1-142LV series of oceanographic pumps draw ambient water through filters at flow rates from 2 liters per minute to 50 liters per minute and can pump more than 40 tons of seawater during a single cast. The LV pumps are designed for use from a hydro-wire and employ advance control algorithms to dynamically optimize flow rates as material accumulates on a filter. McLane WTS-LV pumps are the finest, most accurate, oceanographic pumps in the world today.

The WTS-EC, is configured to draw ambient water through 47 mm pre-filters followed by in-line extraction columns to allow the collection of radio-nucleides, organics, and trace metals from seawater. The pre-filters are identical to those used in the WTS-47FH and the extraction columns can be bypassed, permitting use as a WTS-FH.

The McLane firmware provided with each of these systems makes them easy to use, yet flexible and robust in support of your scientific goals. The operator has control over sampling schedules, start times, sample volumes, flow rates, time limits, and many other parameters. All members of the WTS family use the advanced control algorithms developed for the LV pumps. McLane is always available to assist and provide operational advice, such as proper matching of filter types and pumping flow rates for optimum performance. The user manuals (listed below) are comprehensive and include detailed photos and maintenance information.

Special Features

WTS hardware and software can be customized to meet user needs. For example, multiple intake WTS-FH/EC units can be used to acquire vertical concentration profiles in bottom boundary layers. The addition of external sensors permits action triggered sampling (ATWTS). We will work with you to develop a triggering algorithm based on a simple threshold mechanism, advanced time domain, frequency domain, or statistical techniques.

A fully interactive deployment option is available for the WTS-FH/EC product line. Sampling is triggered by a remote user dynamically interpreting and responding to the changing conditions at the site. Individual sample ports can be prepared in advance for biological, chemical, or other types of samples and used as needed by the investigators.

Our engineering expertise and high performance line of standard time-series oceanographic sampling products enables the scientist to collect the required samples in-situ. Call us today to discuss your project needs and how we can meet them.
