WEBTEC FlowHUB Series, User Manual

English
All FlowHUB’s work on the same theory - the fluid flow is used to move a magnet which is mounted within a piston,
the distance moved is proportional to the flow rate. This movement is measured by a sensitive magnetic device. The
on-board electronics condition the signal and convert the linear movement to fluid flow. The FlowHUB also allows
unmeasured flow in the reverse direction - when reverse flow is present the display will show ‘
-EE-
’.
A temperature probe mounted in the main body provides an indication of the fluid temperature. Options on the FlowHUB
include, analogue output - either 4 - 20 mA or 0 - 5 volt, two programmable switches or both options fitted.
Note . If the current loop is open circuit then the left LED will illuminate either red or amber.
All FlowHUB’s are designed to work with oil at 21 cSt as standard. Special calibration is available over a custom flow
range or at a different viscosity, please contact sales to discuss your application.
