The Greyline Instruments OCF 5.0 open channel flow meter is designed to continuously monitor, display, totalize and data log flow through any flume or weir. Featuring an ultrasonic sensor that mounts above the flowing water, the OCF 5.0 will not obstruct the flow nor be prone to fouling.

The OCF 5.0 is easy to set up and operate. Use the built-in Keypad/menu system to select your flume or weir from the menu and to choose the measurement unit. Flow reports including minimum, maximum, average and total daily flow can be viewed directly on the backlit LCD display. The OCF 5.0 also includes a built-in, 2-million point data logger and flow reporting system. Connect a flash memory stick to the flowmeter's USB output to download log files and then view your data in graph and table formats with 'Greyline Logger' software.

The Greyline Instruments OCF 5.0 open channel flow meter has an isolated 4-20mA output which can transmit flow data to remote chart recorders or displays. The two control relays (upgradeable to six) are programmable for level/flow alarm, and flow proportionate pulse (for samplers, chlorinators or remote totalizers). An Intrinsic Safety Barrier is optional for sensor and cable installation in hazardous rated locations. The separate, watertight electronics/display enclosure is mounted at a convenient location within 500ft (150m) of the sensor.
