MEASUREMENT OF FLOW IN THE TANK

Based on the Terms of Reference for the Development of the Reconstruction Project of the local water supply system Međudražje in the settlement Međudražje - MZ Zavalje - City of Bihać, Center for Design and Consulting d.o.o. Banja Luka hired us to perform a 48-hour flow measurement at a pre-determined measuring point in the reservoir.

As part of the project task, among other things, it was necessary to measure the flow in order to see and assess the abundance of springs and available water, for the settlement Međudražje, and at the entrance to the reservoir from the spring.

In order to fully understand the condition of the source and the capacities currently available in the distribution of drinking water, the measurement was performed with an ultrasonic portable flow meter AQF 2000.

The ultrasonic flow meter is installed on the LŽ 80mm pipeline and programmed for a measurement interval of 1 min in a time period of 48 hours.

After the measurement, a report was made with accompanying photo documentation, a measurement diagram and an overview of the minimum, maximum and average flow at the inlet to the tank.

Flow and pressure measurement

As part of the continuation of the conceptual solution of the problem of water supply from the spring on the water supply system of the forestry Gorica in Šipovo, flow measurement and pressure control were performed.

By measuring the flow of water on the two catchments from which the said water supply system is supplied, the available quantities were determined, ie their yield.

By visiting and visually inspecting the part of the indented pipeline 100 mm from the catchment to and behind the connection point, the problems that need to be eliminated in the next period in order for the system to be functional were also determined.

By recording the height elevations of the pipeline, for which there has been no documentation of this type so far, and by making a longitudinal profile, a plan of necessary repairs will be made. In addition to the rehabilitation of existing facilities, as well as the replacement of certain fittings and valves in line shafts and overflow chambers, it will be necessary to build some additional facilities, in order to put the network in the length of about 6 km into operation.

Pressure measurement with control was also performed on the air valve which has the function of reducing the pressure towards the chamber-tank Čardak.
