Environmontel Ltd, an established flow-survey company based in Worcester, selected HydroLog4 as their sewer-flow survey information system for use by survey teams on short-term drainage-area surveys and other longer-term monitoring projects. The software was selected because it met the clients need to be able to import virtually any file format or parameter and also for the facilities to process flow from either stage-discharge or velocity-area (Doppler) based flow-meter devices.
