Doppler Flow Meters

Doppler flow meters are a starting point for difficult-liquid applications where suspended solids or bubbles can support a Doppler measurement approach. Daly Middle East lists Pulsar clamp-on and portable Doppler options for relevant full-pipe applications, including wastewater, slurries and challenging industrial liquids.Selection depends on the liquid condition, whether the pipe remains full, pipe material and size, external access and whether the need is a temporary survey or a fixed monitoring point. Browse the listed DFM 6.1, PDFM 6.1, FlowPulse and related products below, then compare them in the ultrasonic flow meter selection guide.For sizing, provide the liquid description, solids or aeration condition, pipe details, flow range, site photographs and the display, data or control output required.PORTABLE OR FIXED: a portable Doppler model can be relevant for checks, commissioning and surveys. A fixed Doppler instrument or sensor may be better suited where ongoing monitoring is required. Confirm the measurement duration, local display or data requirement and the interface to any control or monitoring system.RELATED ROUTES: for clean liquids, compare transit-time options before selecting Doppler. For open channels or partially full pipes, review the area-velocity and open-channel range instead. The listed product cards provide the model pages; the enquiry should include site photographs and the actual process conditions.
