VSE EF Ecoflow Aluminium Flow Meter

As a cost-effective and lightweight alternative to the VS volume sensor, we have launched the VSE EF ecoflow series onto the market. The VSE EF ecoflow aluminium flow meter uses the same gearwheel pairs as in the VS.

The flow meters work in accordance with the same displacement principle as the VS, and measure viscous media as an inline device. The pulse frequency is proportional to the speed of the measuring unit wheels driven by the volumetric flow. The pulse evaluation is carried out using VSE evaluation electronics or any other evaluation device. The flow meters are ideal for low pressure hydraulics, lubrication systems, spray coatings, and with the high temperature option, also for hotmelt. Based on the same meshing gear principle as the VSE series VSI and VHM, the VSE EF ecoflow sensor measures viscous media, however as in-line-device.

Optional:

LCD flow display with analogue output and two limit values, mounted on the flow meter. The impulse frequency is proportional to the revolutions of the gear wheels, which are driven by the volume stream.

The impulse processing is made by means of VSE made or any other electronical readout. The VSE EF ecoflow is a economical alternative to the VSI series for applications that require lower accuracy, temperature and pressure.
