WCS | Data Logger

The GSR and PSR data logger families measure and register different quantities such as pressure, level, flow, temperature... Power supply is adapted to the application site. It can be grid, battery or solar powered. According to their construction we distinguish compact loggers and loggers with dislocated electronics. Data transfer may be local, networked or wireless.

Data loggers GSR 120 NT and GSR 120NTG

The GSR 120 logger family consists of two data loggers: type GSR 120NT which measures and registers levels (or pressure) and temperatures and type GSR 120NTG, which in addition to level (pressure) and temperature measurements records also the conductivity of the media (water).

They are characterized by a compact stainless steel immersion housing, battery or external power supply, communication connection RS 485 and the possibility of connecting a GSM modem for wireless data transmission.

Data loggers GSR 130NT and GSR 130NTG

The GSR 130 logger family ist similar to GSR 120, but the GSR 130 logger measures and registers absolute level (pressure) and therefore needs no vented connection cable. The Data logger GSR 130 NT measures and registers level (pressure) and temperature, the GSR 130 NTG measures and registers level, temperature and also conductivity of the media (water).

The data logger is descended with an ordinary cable-rope at a suitable place in a well and fixed at the top. The data logger has to be taken out of the water for data transmission.

WCS | Water Loss Control System

In the transportation of water from sources to end consumers some water always gets lost.

Any significant deviation means an additional loss of water.
This means high costs because of expensive electricity used up to pump the water, the necessity find to new resources, pipelines are more burdened and last but not least the government has introduced sanctions - a fee on water loss.

The system consists of a data logger, an inductive flow meter and a pressure transmitter. The data is stored in the memory unit. With the help of a GSM modem the archived data (daily) or alarm information (when the set parameters are breached) can be sent wirelessly to a designated location.

With the analysis of information provided by individual data loggers deviations or differences in the flow and pressure can be detected at different time intervals ( at night, weekdays or on weekends ...)

Any significant deviation means an additional loss of water.

Depending on the data logger's location we can quickly response and find the area that has to be improved. The power supply can be adapted to the application location, the system can be grid, battery or solar powered. A quick and easy assembly provide good mobility of the system.

Application:

The measuring system allows measurements and registration of pressure, temperature and flow, as well as indication of water intrusion and unauthorized entry into the facility.

Power supply can be battery, 230 VAC grid or solar. Data from the data logger can be transferred to a PC locally or wireless (installed GSM modem).

Inductive flow meter:

mounting on the pipeline without flow interruption, connected to the data logger, battery, solar or grid powered, mechanical connectionG5/4, measurements of very low flows, robust construction
