Hengesbach Magnetic-inductive Flow Meter Volumtec

Hengesbach Magnetic-inductive Flow Meter Volumtec is for the measurement / dosing of flow and Volume of all conductive liquids from 5 µS / cm designed with high hygienic requirements. Thanks to its compact, reduced and equally effective design, made entirely of stainless steel, as well The electrical features of the VOLUMTEC meet the demands of modern flow measurement at a high level.

Also for applications with small pulsating flows, e.g. in systems with piston pumps, that is VOLUMTEC can be used due to its special electronics, since the signal is smoothed.

The integrated monitoring processes of the entire measurement chain not only result in a reliable, but also a very precise measurement – officially confirmed by the European OIML certificate – and thus perform an essential Contribution to the monitoring and optimization of the production processes.

A special function enables initiation an inspection routine to document the process safety in a quality certificate. A rotatable display integrated as standard ensures not only during the commissioning phase constant observation of the measured values ​​and therefore the process, but also a quick and easy one Can be operated without opening the device.

Text messages and the flow profile are shown on the graphic display, this and the “Quick Start” – Menus are useful for commissioning. In inaccessible installations, the activation of the Bluetooth interface is positive, as is the case with the Change of parameters or their readability.
