The standard method for determining open channel flow is to measure the height or HEAD of the liquid as it passes over a weir or flume. Princo’s SmartSonic™ Open Channel Flowmeter transmitter has built-in programmed characterization for virtually every standard weir or flume. Incorporating unique Narrow Beam Technology, SmartSonic™ transmitters are very simple to install and start-up and can be supplied factory pre-calibrated. In addition, they are backed by our unique 10-year warranty. |
