Description

VSE EF Ecoflow Aluminium Flow Meter works in accordance with the same displacement principle as the VS, and measures 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 hot melt. 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.

VSE EF Ecoflow Aluminium Flow Meter Optional:

LCD flow display with analog 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 or any other electronic readout. The VSE EF ecoflow is an economical alternative to the VSI series for applications that require lower accuracy, temperature, and pressure.
