Open channel monitoring and measuring equipment from Bell Flow Systems utilise the area-velocity measurement technique, providing a continuous or time-sample measurement of water flow. The Mainstream high performance series are designed for users wanting to measure water velocity, level and flow in open channel and partially-filled pipe applications.
Mainstream products available include; AV-Flow Transmitter, Velocity Transmitter, Compact fixed AV-Flowmeter, Premier fixed AV-Flowmeter and the Portable AV-Flowmeter. This range of meters are relatively quick and simple to install without the requirement of a flume or weir and offer a high level of sensitivity ensuring suitability for various flow measurement applications.
Featuring a variety of outputs including 4-20mA signal, scaleable pulse output and GPRS data transmission options. The meters include a bi-directional velocity range for forward and reverse velocities of 10mm/s to 5m/s. ATEX hazardous area sensors are optionally available.
