VSE EF Ecoflow Aluminium Gear Flow Meter As a cost-effective and lightweight alternative to the VS volume sensor, we have launched the VSE EF eco-flow series onto the market. The VSE EF eco-flow aluminum flow meter uses the same gearwheel pairs as in the VS. The rotation of the flow meter gear wheels is sensed by a non-contact magnetoresistive pickup, amplified and emitted as pulses.
The passing of each gear tooth produces a pulse corresponding to a precise positively displaced measured volume. The pulse output can be produced as PNP or NPN signals. The frequency is proportional to the momentary flow.
