About Us

We develop and manufacture industrial flow and level monitoring instruments for measurement and control in water and wastewater treatment, industrial process automation and for environmental monitoring.

Greyline level instruments include ultrasonic level monitors and transmitters, tank level monitoring instruments, pump station level controllers, software and data loggers.

Greyline's ultrasonic flow products include portable meters for troubleshooting and surveys, Doppler flow meters with strap-on sensors, flow switches, open channel flow monitors and area-velocity flow meters.

FEATURED PRODUCTS

DFM 5.0 - Doppler Flow Meter

Measure flow from outside a pipe. The Greyline DFM 5.0 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.

DFS 5.1 - Doppler Flow Switch

Flow Switch With Non-Contacting Sensor; Control Flow from outside a pipe. Recommended for 'difficult liquids' including wastewater, cooling water, slurries, sludge, chemicals, viscous liquids and abrasives. The Greyline DFS 5.1 is ideal for pump protection or to activate flow/no-flow alarms.

FEATURED APPLICATIONS

Irrigation water flow measurement for open channels and partially filled pipes - Water and Wastewater - Pipes and Piping

Greyline AVFM Area-Velocity Flow Meters monitor and totalize irrigation water distributed through a network of canals, channels and pipelines in the United Irrigation District.

Area-velocity flowmeter for measuring sewage and stormwater flow - Water and Wastewater

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.
