WaterQuality Monitoring System Product Description
Global Waters WQMS Water Quality MonitoringSystem allows you to monitor multiple water quality parameters with a fullyintegrated, easy to use, economical system. The standard Water QualityMonitoring System includes our multichannel datalogger (featuring 7 analogchannels and 2 digital channels for data recording) and four of our rugged 4-20mA water quality sensors for measuring water temperature, pH, conductivity, anddissolved oxygen. To customize the Water Quality Monitoring System foryour application, you can select up to three more analog sensors and up to twodigital sensors to monitor additional parameters such as turbidity, ORP, waterlevel, wind speed/direction, rainfall, and more.
Smart Water Quality Data Recorder
The Water Quality Monitoring Systems water quality data recorder features 7analog channels, 2 pulse channels, and USB and serial communication ports. The durable and powerful datalogger is enclosed within a sturdy weatherproofcase. The Water Quality Monitoring System’s datalogger will operate forseveral months before its internal 12VDC battery requires recharging. Formore information on the Water Quality Monitoring System’s GL500-7-2 click HERE.
Powerful PC and PDA Software
The WQMS Water Quality Monitoring System includes Windows-based Global LoggerII software, which makes accessing stored data and setting options easy. The software provides many useful features, such as real time readout,measurement interval and engineering unit selection, station ID setting, andsensor calibration. The WQMS Water Quality Monitoring System also includesWindows CE based PDA software for simple data collection in the field. Data downloaded from the recorder can easily be opened in any PC spreadsheetprogram for analysis and graphic presentation. NOTE: The Palm operatingsystem is NOT supported. For more information on supported PDAs click HERE.
Rugged Water Quality MonitoringSystem Sensors
The WQMS Water Quality Monitoring System comes standard with four rugged andreliable 4-20 mA water quality sensors, including our water temperature sensor,pH sensor, conductivity sensor (with a 0 to 5000µS range standard), anddissolved oxygen sensor. Each sensor is mounted on 25′ of marine-gradecable, with lengths up to 500′ available by special order. The sensorselectronics are completely encapsulated in marine-grade epoxy within a stainlesssteel housing. Each sensor outputs a 4-20 mA signal. For moreinformation on the WQ101, WQ201, WQ301, and WQ401 go to our water qualitysensors.
Remote Communication Options
To add remote communication capabilities, select the GL500-Mod Modem Package fortelephone modem communications (see Options) or the RM100for radio communications. We also offer solar panels and a batterycharger to support your WQMS installation. See the Optionssection below for additional information.
Customize for Your Application
To customize your WQMS, you can select up to three additional analog sensors andtwo digital sensors from Global Waters line of rugged water quality, weather,level, and flow sensors. Please see Options belowand the sensors in the water quality and weather section of our catalog foradditional information. If you require a unique water quality monitoringsystem to meet the needs of your specific application, Global Water can workwith you to design a factory-integrated custom system. Please contactGlobal Water regarding this option.
