NEW - RS5 helical screw flow meter

With the innovative RS5 micro flow meter, measuring ranges from 0.25 ml/min to 1 l/min are possible. Its compact dimensions and low weight open up for many new application possibilities.

Like the larger models in the RS series, the RS5 also impresses with its low-resistance, high-precision, pulsation-free and gentle measurement of liquids with minimal pressure loss. With a measuring range that has been reduced by a factor of 100*, the RS5 sets new standards in precision measurement.

The newly developed sensor technology transforms even the smallest drop into high-resolution signals. The RS5 is ideal for applications with limited installation space or specific weight requirements, such as in plotter-like dispensing and handling equipment. It is perfect for bonding and potting electronic components. The RS5 can be used as an additional component for dosing pumps, including progressive cavity pumps, for actual value control. Thanks to the rotor principle, the RS5 can also precisely measure highly viscous and critical media.
