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 PTFM 1.0 - Portable Transit Time Flow Meter

Recommended for fluids like water, glycol, oils and chemicals. Use it for calibrations, troubleshooting, flow surveys and as a temporary transmitter to replace inline flowmeters. The PTFM 1.0 ultrasonic transducers strap-on the outside of pipes from ½' to 48' (12 to 1200 mm) diameter. The ultrasonic signal works through common pipe materials including carbon steel, stainless steel, ductile iron, cast iron, PVC, PVDF, fiberglass, copper, ...

FEATURED APPLICATIONS

Water accountability portable monitoring for solving flow rate mystery

The Glen Walter Sewage Collection System was built to service 1080 customers in 1989. At the time the population was 850 but by 1995 the sewage treatment plant had already reached capacity. Shawn Killoran took over the Operations Manger position in 1999 and, along with the Mayor and Council, he immediately had concerns about the excess flow.

Non-contacting solution for plugged off flow meters in the oil patch

Wax and solids build-up were plugging off pipes and in-line flowmeters at this oil battery site in Alberta. Read how Petrobakken Energy solved the problem by switching to Greyline DFM 5.0 Doppler Flow Meters with non-contacting ultrasonic sensors.
