This new model OCF 4.0 Open Channel Flow Monitor uses a non-contacting ultrasonic sensor to measure wastewater flow through flumes or weirs. It features a powerful, built-in data logger with on-screen flow reports plus Windows software to retrieve, display and graph flow reports in fully customizable formats.
Other OCF 4.0 features include isolated 4-20mA, 0-5V, USB and RS232 outputs, 3 control relays, a large flow rate display plus a 10-digit totalizer. Calibration and selection of flume or weir are made through the built-in 3-button keypad and user-friendly menu system. Your calibration set-up is password protected and flow data and totals are safely stored through power interruptions. Temperature compensation is automatic and accuracy is ±0.25%.
Options include intrinsically safe sensors, an enclosure heater, and 9-36VDC power input.
