NivuFlow Gauging
Van Walt’s aim is to keep flow gauging simple. To do this we now offer a flow gauging service where we will travel to your site and carry out flow gauging in your stream or pipe on your behalf. Once our site visit is complete, we will issue a full report which will include:- Location photos
- A profile of the bed
- The level of each sampled segment
- The velocity profile over 10 sampled segments
- The flow rate
- The area, hydraulic radius and wetted perimeter
- PDF and .CSV results
