Flow Metering – Where Non-Contact Really is Proving to be ‘No-Maintenance’

Although open channel flow meters have existed for 100’s of years none were able to offer the promise of zero maintenance and long term reliability, combined with
ease of installation and use. Since its introduction in 1999 the Flo-Dar instrument from Flowline has remained the only non-contact area velocity flowmeter available and has now evolved
into several different systems that cover a wide range of applications and industries.
Initially developed and manufactured in the USA and launched after more than five years of research and testing by manufacturers Marsh McBirney, the system was their response to the problems
associated with “conventional” wetted type flow sensors, which until that time, were the principal method used in area / velocity metering.
