Application Background Printer Friendly Version
Manufacturing plants, Public Utilities, Power Stations, Oil & Gas processing facilities and Sewerage plants all have some form of industrial outflow which needs to be measured and reported on.
Hydro Power companies need to measure the volume, temperature and quality of water passed back into the river after it has passed through the turbines.
Traditional coal or gas power stations have cooling water discharges which need to be monitored, to ensure the temperature being returned to a lake or reservoir is not above acceptable limits.
Sewerage plants must measure and record any effluent from sewer treatment plants which is being discharged back into the environment.
Measurements are typically flow, quality and temperature, and the measurement environments can be in pipes, or in outflow channels
For measurement of flow, there are several methods, an inside pipe or in channels mechanical propeller system to measure velocity and a separate instrument, for example a float and pulley system to measure depth. With velocity and depth, and with the shape and the width of the channel or pipe, the actual flow can be calculated.
Unidata offers a combined 6526 Starflow instrument which measures water depth using pressure sensor technology, and water velocity using ultrasonic technology and this small instrument can then be installed in an open channel or a closed pipe, either round or oval /
ovoid and the Starflow can determine the actual flow mathematically based on the entered channel definition.
For measurement of other parameters for water temperature, water quality for example electro conductivity (EC) , pH ( PH) , dissolved oxygen ( DO) can be measured with separate instruments.
In some instances turbidity of the water / outflow may also be measured..
The 6526H Starflow instrument would typically be installed at the base of the outflow channel using a mounting bracket and a concrete slab and the cable would be fed to a small enclosure at the side of the channel.
Consideration needs to be given to providing a power source. If primary power is available, then a small battery backed up power supply could be used. A small solar panel could be used, with a solar power recharge system, if there is no easily accessible primary power system. A small enclosure with a lithium battery pack could be added, and this would provide a completely independent power source for the measurement station for more than 2 years, depending on the instrument s chosen.
A Neon Remote Terminal, either cell phone based or satellite based could read the instruments, perhaps every 5 minutes, and then store the data and send the data up to a Neon Server every hour so the data can be displayed on a web browser anywhere in the world.
The data could also be scanned for any out of limit condition and activate an alarm and or send an email or a text message to the appropriate people to take any action following an out of limits condition.
While it is unlikely that there would be a requirement for intrinsic safe instruments in this application, the issue needs to be considered. For vented sewers, there is less requirement for intrinsic safe instruments. For closed sewers perhaps intrinsic safe is a requirement.
