The Greyline DFM 5.1 is designed for 'difficult liquids' that would damage regular flow meters - wastewater, slurries, sludge, chemicals, viscous liquids and abrasives. There is no obstruction to flow and no pressure drop. The non-intrusive, clamp-on ultrasonic sensor fits any pipe 1/2' (12.5 mm) Inside Diameter or larger. The electronics/display enclosure can be mounted nearby.

FEATURED APPLICATIONS

Area-velocity flowmeter for measuring sewage and stormwater flow

Greyline AVFM Area-Velocity Flow Meters are installed thoughout the country by Teletronic Denmark to monitor municipal sewage and stormwater. Application photos and descriptions illustrate flow monitoring in manholes and open channels.
