Blue and White F-461

Flow Meter

The highly engineered design, and materials of construction of the F-460 and F-461 Series Variable Area Flowmeters, makes them well suited to applications where no metals can enter the fluid path (Ultra Pure), and for highly corrosive applications.

Global Water FP-101/FP-201

Handheld Stream Flow Meter

The Global Water Flow Probe is a highly accurate water velocity instrument for measuring flows in open channels and partially filled pipes. The water velocity probe consists of a protected water turbo prop positive displacement sensor coupled with an expandable probe handle ending in a digital readout display. The water flow meter incorporates true velocity averaging for the most accurate flow measurements. The Flow Probe is ideal for storm water runoff studies, sewer flow measurements, measuring flows in rivers and streams, and monitoring velocity in ditches and canals.

ISCO 4230

Bubble Flow Meter

Isco 4230 Bubbler Flow Meters use an internal air compressor to force a metered amount of air through a bubble line submerged in the flow channel. By measuring the pressure needed to force air bubbles out of the line, the flow level is accurately determined.

Measurement accuracy of the 4230 is not affected by wind, steam, foam or turbulence, nor by suspended solids and rapidly changing head heights that can cause problems for some bubbler flow meters. Because only the bubble tube contacts the flow, corrosive chemicals are not a problem. The 4230 also resists damage by lightning and debris, making it ideal for stormwater applications.
