Invetia MT723 – Case Study Flow and pressure monitoring in water distribution networks

Project Purpose: Monitoring flow and pressure in the main nodes of water distribution networks,

including detection losses

Beneficiary: Water Company Somes SA Cluj-Napoca

Locations: Cities Cluj, Zalau, Dej, Gherla, Huedin, Dej, Jibou, Cehu Silvaniei, Simleu Silvaniei

Value Investment: 377.444 Euro

The solution implemented: To monitor flows and pressures in water distribution networks we used

telemetry system with self-contained battery, composed of datalogger Inventia MT723,

electromagnetic flowmeters Hydreka Hydrins2 with local display, pressure sensors Huba Control

DT511 0-10 Bar.

Information taken from monitoring points are transmitted to the regional dispatch. In these

regional dispatch were used software packages SCADA Siemens SIMATIC WinCC 7.0.

Measurement Points: 52 locations

Regional Dispatch: 4 (Cluj, Huedin, Gherla, Dej)

Data taken from measurement points: instantaneous flow, flow totalizer positive, negative and

total, low water alarm, alarm exceeding maximum flow, pressure, maximum pressure exceeding

alarm, low battery alarm, GPRS communication status

Regional Dispatch: For each city are presented in SCADA application synoptic maps with

positioning of each measurement point, and by accessing its displays information on that point.

Data are collected from measuring points hourly (the time period is configurable by the customer)

Based on data collected from datalogger we can display in Regional Dispatch the list of alarm,

reports for different time, graphic evolution of the parameters you want.

Local data can be downloaded directly from datalogger to a laptop via USB connection.

Instant Data from measurement points :

Warning messages: When defined threshold is exceeded for flow and pressure, no voltage, lack of

water in pipe, SMS messages are automatically transmitted by persons directly involved in

operating of water distribution system (intervention team, head of department, ...)
