MEASUREMENT ON WATER SUPPLY SYSTEMS
If there is a significant percentage of losses on the system in terms of non-revenue water made up of several aspects, they are the driver of all other financial losses. Loss means the need for increased water production, which emphasizes the greater amount of electricity consumed, higher maintenance costs, increased costs in the process of purification or production of drinking water.
In a comprehensive analysis, the basic and starting point is, as Leonardo da Vinci once said, "Before any work, first take a measurement." In order to be able to realistically see the situation on one water supply system, it is necessary, in addition to the number of consumers, to know the basic parameters of water supply, the amount of delivered water, as well as minimum and maximum pressures in all altitude supply zones.
In addition to consulting services that include condition analysis, loss reduction plans, network zoning, our team is at your disposal for comprehensive measurements on your plumbing systems. With the equipment of renowned manufacturers that guarantee accuracy in measurement, if necessary and to the extent, we can perform:
- Water flow measurement on pipelines and installations
- Measurement of flow and temperature on hot water pipes
- Pressure measurement on pipelines and connections
- Measurement of noise on pipelines
- Routing of metal pipes and cables
Flow measurement, in addition to already existing measurement points, can also be performed at temporary measurement points that are determined for the purpose of more comprehensive measurement, i.e. measurement of DMA zones and their subzones. Measurements can of course also be performed in pumping plants and tank spaces, with certain conditions that must be met in order for the accuracy of the measurement to be as precise as possible, i.e. within the limit of the permitted tolerance. Flow measurement on hot water pipes is done with hot water probes, which are certified for temperatures over 125 °C, as well as temperature measurement with hot water probes.
Hot water flow measurement data, as well as temperature values on the supply and return heat pipes, as well as the amount of delivered heat energy, can be used to create a study on energy efficiency or calculate the percentage of heat energy losses on the heat pipes.
Pressure measurement can be performed on underground as well as above-ground hydrants on pipelines, as well as on plumbing installations of various profiles. The pressure measurement range ranges from 0.00 bar to 30.00 bar.
All these measurements can be performed at various measurement intervals from 1 sec to 1 h, all according to customer requirements or project needs. The memory capacities of measuring instruments are large and meet the needs of storing measured data continuously for up to a month of measurement with a minimum interval of 1 sec.
Pressure measurement for 24 hours at any location, with creation of a certified report Elaborate measurements, we provide as a service to all consulting and design bureaus. The preparation of the Elaborate, which contains a sketch of the location of the pressure logger measurement site, as well as a diagram of 24-hour pressure measurement and a table of average pressure values, is carried out for the purposes of obtaining urban-technical conditions for the construction of residential and commercial buildings, i.e. for the calculation of fire sprinkler systems (Fire sprinkler system).
Noise measurements on pipelines and installations are performed in order to obtain a clearer picture of the state of the water supply network where the meters are installed. Therefore, the basis of these measurements is to look at the condition in a very fast and efficient way and determine potential fault locations based on the recorded noise.
For all performed measurements, a diagram, tabular overview or software presentation of the obtained results is performed. If necessary, ie according to the contractual obligations based on the Project, a more detailed analysis of measurement results is performed and based on it, the following steps are determined in terms of inspection and control of the network, and research of losses in the water supply system.
TRACING OF METAL PIPES AND CABLES
In our work so far, we have encountered many times a problem where our clients are not able to present us with the location of the installations. In order to be able to do the work, it was necessary to use measuring equipment and instruments for the detection of underground metal installations, as well as electrical and ppt installations. We have a metal pipe and cable detector Radiodetection RD 400 LCTx that we use in all the projects we work on, in order to get the most accurate data. With the device, it is possible to trace metal installations as well as electrical installations under voltage, as well as PTT infrastructure. Successful routing is achieved for underground installations located up to a depth of 2m, regardless of the type of ground surface.
