CLAMP-ON FLOWMETERS FOR TUNNEL AND ROAD DRAINAGE.
Tunnels and Road contstruction – Ultrasonic flowmeters are increasingly being used to check and monitor the water discharge in tunnels and on roads during (heavy) rainfall. Daily commuting and transportation should of course not be hindered by flooding.
All excess water must be pumped out of tunnels and roads as quickly as possible. Measuring instruments offer the solution. However, in an existing tunnel or road, the traffic should be hindered as little as possible when installing a measuring system. Breaking open the drain pipes to install a conventional – inline – flowmeter is not an attractive option.
