H-ADFM - Horizontal Acoustic Doppler Flow Meter (ADCP)
- Advanced Flow Measurement Performance The most precise and accurate choice for metering sites in very large pipes and open channels
- Revolutionary Flow Meter Has set new standards for flow measurement in wide channels and enabled doppler technology for open channels in applications of 10ft or greater
Overview
The H-ADFM is a revolutionary flow meter that has set new standards for flow measurement accuracy in wide channels and has made pulse doppler technology available for open channel applications with a width of 10ft or greater. The H-ADFM mounts on the side of a channel which allows easy access for maintenance. It measures the horizontal distribution of velocity within the flow, across the channel, using pulse doppler velocity profiling technology. Horizontal profiling increased information on the flow conditions and velocity structure that can not be provided from a single point surface measurement
The H-ADFM is the most versatile and most accurate flow meter available for metering sites in open channels and very large pipes including chlorine contact basins and other applications with rapidly changing, non-uniform, near zero, zero , reversed or backwatered flow conditions.The H-ADFM sensors can also be 'stacked' to provide horizontal profiles at multiple depths in the flow, providing superior data quality and increased accuracy eve in difficult hydraulic conditions.
