...

The importance of measurements and recordings on stormwater treatment facilities

is constantly growing. It is not only authorities who demand proofs and protocols on

impoundage events and overflow volumes; such data moreover represent an

important planning basis for the expansion of previous settlement areas.

In Germany e.g. there are currently around 24.000 stormwater overflow tanks and storage

sewers in use (status as of 01.10.2007). According to the Water Act, operators are

responsible for the correct operation of such facilities.

To prevent water pollution and to ensure environmental protection, these plants (such as

municipal wastewater treatment plants, sewerage systems, stormwater treatment plants

and industrial wastewater treatment plants) need to be checked regularly. Moreover

operators are obliged to create protocols on several operational data.

Using high-quality measurement systems alone is not enough when it comes to

ensuring plausible and accurate results.

Having gained 25 years of experience with planning and configuring the best

possible measurements and transmission systems for stormwater treatment plants,

our engineers and technicians are capable of providing professional and reliable

solutions.

NIVUS - your expert for measurement solutions on stormwater overflow tanks

Tank in main connectionMeasuring tank impoundage and tank overflow

EVENTLOG

Devices:

Level measurement: 2 ultrasonic sensors or

pressure measurements

Data/Transmission: data logger/GPRS

Logging: software-independent,

D2W Internet platform

Modern data logging does not need to be expensive...

As a worldwide leading developer, manufacturer and supplier of measurement

systems for the water industry, NIVUS offers a range of products which allow cost-

efficient, economic and reliable recording and logging of measurement data even

without being dependent on public electricity networks.

The market reveals large price differences regarding overall costs particularly if

facilities need retrofitting or smaller tanks are not yet equipped with appropriate

logging systems

Data transmission and server utilization more cost-effective than DSL connection.Given a 5-minute recording interval, two transmission events per day and two error

messages via SMS (high priority) per month the total costs are less than 10 Euro/month.

NIVUS event logging - reliable and convenient

EVENTLOG

Event-relevant data are transmitted via

GPRS from the outpost to the D2W

Internet portal where they are saved

reliably.

It is here where outposts are managed

and data are evaluated, calculated and

logged. Users have secure access to

their data and logs without the need for

particular PC software. Using an Internet

explorer it is possible to directly print out

or to save the data on PC/Laptop.

Create data logs with just a few clicks
