We have developed and we are producing our own softwer for online monitoring of water levels. Transfer of data is provided by GSM and GPRS modules. For registration of water level we are using different kinds of sensors.

All measurement results and collected data are fast processed with high quality according to WMO and BHP standards. We have specialized programs and well educated staff for data processing. All processed data are stored into our own data base HIS 2000 Hidroing.

In Republic of Croatia most of built instruments are produced in Seba and OTT factory. Other stations have HMV and HMV-S instruments made in Croatia. Some of stations are equipped with instruments that have sensors which turn hydrostatic pressure into water level. For online monitoring various sensors are used (digital or analog). For checking accurancy of instruments, next to instrument we have to incorporate a level gauge with standard partition of 2 cm. That is the most valid way to check instrument accurancy.

At chosen microlocation we incorporate level gauge. Mostly, we use vertical or sidelong level gauges. Vertical level gauges are emaled and have standard partition of 2 cm. Sidelong level gauges are hand made by our subcontractors.

To make a flow curve, we perform hydrological measurements. They are mostly done with current meter for flow velocity and if needed with method using outrigger or vessel. We have numerous current meter for flow velocity and all other equipment for all measurements (even complexed like Dunav, Sava, Drava, Kupa). Our current meters for flow velocity are made in SEBA and OTT. We are also performing sampling of waste waters from industries in collaboration with authorized laboratories. Simultaneously we measure water flow.
