The Flow Switch RIV600 have high visibility on each side and a clear reading of the scale.
Thanks to the conformation of the cone, at regular increases of flowrate match movements equally regular of the shutter (linear progression).

RIV600 series can be equipped od one or 2 alarm sensors at reed contact, possibly supplemented by red LED (green on demand) for a signaling field of the presence or absence of the flowrate predetermined.
