Van Walt Ltd | World-class equipment for environmental professionals

New! Flow gauging made simple

Van Walt’s aim is to keep flow gauging simple. We now offer a flow gauging service where we travel to your site and carry out flow gauging in your stream, and issue a report after each site visit. Max, fully trained in the use of the NivuFlow Stick will be your friendly face on site for gauging and site surveys.
