We develop, manufacture and market industrial flow and level monitoring instruments including ultrasonic level transmitters, flow meters and open channel flow meters. Greyline’s primary market is environmental - especially water and wastewater treatment systems. Customers include industry and municipalities. Modern research facilities at Greyline include closed pipe and open channel flow systems. With years of steady growth, Greyline products are sold and supported worldwide.

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

Greyline - Model OCF 5.0 - Open Channel Flow Monitor

Continuously monitor, display, totalize and data log flow through any flume or weir. The OCF 5.0 includes a non-contacting ultrasonic sensor that mounts just 8' (203.2 mm) above the flowing water. It is accurate (±0.25%) and reliable. There is no obstruction to flow and no fouling. Use the built-in Keypad/menu system to select your flume or weir from the Menu and to choose measurement units (gallons, liters etc.).

Greyline - Model AVFM 5.0 - Area-Velocity Flow Monitor

Monitor flow through open channels, partially full sewer pipes and surcharged pipes without a flume or weir. Ideal for stormwater, combined effluent, raw sewage, irrigation water and streams. Calibration is simple: enter the pipe diameter or channel shape and the AVFM 5.0 computes the flow volume and displays the flow rate. Measure forward and reverse flow and calibrate to channels of any shape.

FEATURED APPLICATIONS

Pump station level controllers for pump staton call outs

Town operators were plagued by high level alarm call outs at two new sewage lift stations. Read how they used Greyline`s hybrid ultrasonic level controllers with dual sensor capability to put an end to level alarms.

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.
