RS5 Micro-Helical Screw Flowmeter

Like its larger brothers in the RS series, the RS5 also excels with its exceptionally low pressure loss, high-precision, pulsation-free and gentle measurement of liquid and incredible resolution of up to 1.5 million pulses per Litre. With a measuring range 100 time lower than the RS40 model, 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 helical rotors principle it can also precisely measure highly viscous and critical media.
