FLOW INDICATOR-TOTALIZER WALL-MOUNT VERSION
8025 flow display, 2 totalizers, enclosure IP65
2.2 Design and Measuring Principle
Design
The flow indicator totalizer compactly
combines a flow sensor and an electronic
board with display in in a splash-proof
plastic IP65 enclosure.
The sensor part consists of a transducer
and an open-cell paddle-wheel.
The electronic component converts the
measured signal and displays the actual
value and the totalized amounts.
The wall-mount version consists of a
transducer with display in a splash-proof
plastic IP65 enclosure.
The associated flow sensor is type 8020/
8030 with coil.

Measuring Principle
When liquid flows through the pipe, the
paddle-wheel is set in rotation producing a
measuring frequency in the transducer
(coil), which is proportional to the flow.
The frequency modulated induced voltage
is proportional to the flow velocity of the
fluid. A conversion coefficient, specific to
each pipe (size and material) enables the
conversion of this frequency into flowrate.
This coefficient (Factor-K in pulse/liter) is
available in the instruction manual of the
insertion fitting (S020).
The electronic is supplied with two 9 VDC
batteries.
The flow indicator totalizer can measure a
flow rate as from 0.5 m/s (1.6 ft/s).
