Flow Sampling System Product Description
Global Water's Flow Sampling System is a unique water monitoring package.  This package includes an easy-to-use lightweight composite water sampler, an open channel flow monitor, and a data recorder that includes software, allowing easy upload of data to a laptop, desktop, or PDA for transfer to spreadsheet programs.  For more information on supported PDAs click HERE.  This compact package is portable for field installation and fully customizable to meet your monitoring needs.

Composite Water Sampler
Global Water's flow-proportional composite water sampler is enclosed in a rugged, rainproof, lockable carrying container.  The composite water sampler includes a 2-gallon polyethylene wastewater sample bottle for collecting composite samples, a peristaltic sampling pump, a control panel (no programming required), and a rechargeable gel cell battery.  Also provided is a sample pickup hose and a battery charger.  Optional additions include glass sample bottles, refrigerated containers, portable ice containers and more.  Visit the WS700 Composite Sampler page for more information on the flow proportional composite water sampler.

Open Channel Flow Monitor
Global Water's FC220 Open Channel Flow Monitor is a reliable and accurate instrument for measuring and totalizing open channel flows for all flumes and weirs, as well as for any gravity-type open-channel flow application.  The flow meter measures water depth using any 4-20mA water level sensor's output including Global Water's highly accurate submersible pressure transducer or ultrasonic water level sensor and the flow meter's powerful microprocessor instantly calculates and displays water flow and totalizer values in user selectable units using one of several water flow calculation modes.  The Open Channel Flow Monitors have an 8-button keypad that easily guides you through the versatile setup menus.  Visit the FC220 Open Channel Flow Monitor page for more information.

Flow Data Recorder
Global Water's flow data recorder includes Windows-based and PDA software, which provides many useful features, such as real time monitoring, measurement interval and engineering unit selections, station ID, and sensor calibration.  The Global Water Software makes accessing stored data and setting options easy.  The flow sampling system monitors both flow rate and total flow recording flow rate and relay output pulses for your records.  Data downloaded from the recorder can easily be opened in any PC spreadsheet program for analysis and graphic presentation.  Visit the GL500 Datalogger page for more information.  NOTE: Model FSS100 flow sampling system does not include datalogger.

Bluetooth Capability
The AK1500 Bluetooth Adaptor was designed to eliminate the need for custom PDA cables to communicate between your PDA and the flow sampling system's data recorder.  The adaptor connects to the FSS300 flow sampling system's data recorder serial port using the same interface cable provided with the software-cable kit.  The interface operates from a single 9 volt battery and is turned on automatically when the cable connects the flow sampling system and Bluetooth adapter.  Because the Bluetooth module consumes power when turned on, it is recommended that the cable be disconnected from the flow sampling system when not in use.  A red LED shows the power status and is on continuously while the adaptor is plugged into the flow sampling system.  There is also a blue LED that shows the status of the Bluetooth connection.
