Water Quality Case Studies

Our systems have helped a variety of organizations reach their goals.

The following are just a few of these:

Campbell Scientific’s CR850 dataloggers are at the core of mea-

surement stations that monitor water quality in coal-mine runoff

at the West Coast of New Zealand. Automatic lime dosing raises

the pH of the Mangatini stream to ecologically viable conditions.

A Campbell automated monitoring and control system maintains

optimal dissolved-oxygen levels on Lee’s multiple-pond catfish

farm in Macon, Mississippi. Our equipment eliminated the need to

manually check dissolved-oxygen concentrations several times a

night. Alarms are sent via RF to a computer.

Campbell gear is used to monitor the cleanup of the Susie Mine

near Rimini, Montana. Our CR1000 datalogger acquires and stores

data from multiple sensors and transmits the data to a stationary

ground unit, from where it is sent to an Internet site. The sensors

measure temperature, pH, dissolved oxygen, and water flow.

For the New Zealand coal-mine, our equipment monitors turbidity,

water temperature, pH, water level, general weather, and present weather.

Sensors for Water Quality Measurements

Almost any water quality sensor, individual or multi-

parameter, may be used with the system, allowing

the system to be customized for each application. We

helped create the original SDI-12 standard, so you can

be sure our systems are SDI-12 compat-ible. In

addition, nearly all available flow, level, and

meteorological sensors can be measured, generally

without external signal conditioning.

Communications

The availability of multiple telecommunications and on-site

options for retrieving data also allows systems to be customized

to meet exact needs. Options include: voice-synthesized phone,

telephone, cellphone, satellite, radio, Ethernet, short haul, meteor

burst, coaxial cable, and storage module. Protocols supported

include SCADA, DNP3, and Modbus.

Systems can be programmed to send alarms or report site condi-

tions by calling out to computers, phones, radios, or pagers. Real-

time or historical data can be displayed or processed with

Campbell Scientific software. Data can also be exported as ASCII

files for fur-ther processing by spreadsheets, databases, or analysis

programs.
