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.

Open Channel Flow Monitor
Global Water's FC200 Open Channel Flow Monitor is reliable and accurate for measuring and totalizing open channel flows for all flumes and weirs, as well as any gravity-type open-channel flows.  The flow monitor is pre-programmed with over 20 different flume and weir characteristics and can also be programmed for your unique application.  The unit measures water depth with Global Water's highly accurate pressure transducer and instantly calculates (for display and output) water flow and totalizer values for any depth-to-flow relationship in any engineering units.  The Open Channel Flow Monitor is easily set up in the field using a unique four-button programming system.

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 data recorder monitors and logs both flow rate and total flow for your records.  Data downloaded from the recorder can easily be opened in any PC spreadsheet program for analysis and graphic presentation.
