Main Flow Meter Technologies
Variable Area (Rotameters)
Mechanical rotameters use a float moving in a tapered tube to measure volumetric flow. Available in inline, panel-mount, or saddle-mount formats, they feature durable, corrosion-resistant materials with direct-reading scales
Paddlewheel Flow Meters
Digital paddlewheel meters provide fast response flow rate and total display. Their LCD offers up to four decimal places, and they support flow rate alarms and analog outputs for automation.
Ultrasonic Flow Meters
Blue‑White’s ultrasonic meters accurately measure chemical feed flows as low as 10 mL/min. These non-mechanical meters are suitable for inline installation and offer isolated 4–20 mA outputs for system integration.
Typical Applications
-
Chemical feed metering in water and wastewater
