Economical and practical

Used with a controller, you can independently monitor four sensors with convenience.

Non-magnetic sensing technique

Hach’s Impeller Flow sensors unique non-magnetic sensing technique is impervious to fouling from metal particles. The non-magnetic sensing technique reduces drag for superior low-flow and low-volume measurement accuracy.

Superior low-velocity performance

The forward-swept, six-bladed impeller has significantly better low-flow, low-velocity characteristics than conventional four-bladed impellers to provide higher measuring accuracy.

Wide rangeability

Variable frequency square wave signal
