Trends in metering potable water

Abstract

Sustainable management of drinking water distribution systems requires information on the operating status of system components to identify the best operational management measures. The ability to acquire information on tank levels, pipeline flow and real-time pressure offers an efficient and cost-effective management perspective, and enables wider monitoring, which can improve (physical) security as well. The technology of measuring instruments for hydrodynamic variables, used to monitor potable water systems, differs in their independence from electronic data acquisition components and ability to connect to remote data communication systems. Advanced water measurement infrastructure is characterized by the ability to capture data with measurable errors from anywhere in the system, without restrictions on communication type. This paper deals with the measurement of hydrodynamic parameters and a proposal for water meter classification. It includes analysis of the main water meter and data tele-acquisition infrastructure. Several selection criteria are evaluated with respect to their ability to support mathematical hydraulic models and expert systems for water distribution system management.Key words: advanced metering infrastructure (AMI), internet of things (IOT), potable water, sustainable water management, water distribution system (WDS)

Investigation of linear models for control of water flow and temperature in a water supply system

“…For modeling, we use VisSim [25], which can be combined with the MATLAB program and is independent software. This program has the ability to optimize.…”

Practical pressure management for a gradual transition from intermittent to continuous water supply

“…Measuring instruments, real-time network monitoring, and control equipment were included to enable real-time knowledge (Maiolo et al 2019). The entrance to the sector was instrumented with: Arkon electromagnetic flowmeter with pulse output, starting flow of 0.5 m 3 /h maximum flow of 200 m 3 /h and +2% accuracy; a Bermad pressure regulating valve (PRV) and Pegasusþ pressure control system developed by HWM-Water Ltd (Cwmbran, UK) were installed to control upstream and downstream pressure/flow; two data loggers Multilog LX with two pressure and one flow channel developed by HWM-Water Ltd (Cwmbran, UK) were set in the most unfavorable points (high and low) within the sector to record the pressure/flow (Figure 2).…”
