Description
General
This Electronic digital meter features a turbine
measurement system, designed for precise
measuring of low viscosity fluids. It is divided into
two using macrogroups:
1. With body made of inconductive plastic
material of light color, designed to be used with
water/urea solution.
2. With body made of conductive plastic material
of dark color (assessed resistance: 50 ohm),
designed to be used with DIESEL FUEL,
WATER and windscreen fluids.
The circuit board can be rotated with respect to
its housing, thus allowing easy display reading in
any position. The circuit board housing, easily
accessible, is enclosed by a plastic cover sealed
through a rubber guard acting as a gasket as well.
The whole unit can be easily removed by
unscrewing the 4 screws securing the circuit board
and the cover.(Fig.2)
Turbine Measurement System
The turbine is placed inside a hole through the
body of 8424, fitted with threaded inlet and outlet.
The body of 8424 is made of a plastic material that
allows several types of threads with relevant
combinations. 8424 has two rubber guards which
are designed to act as gaskets thus reducing the
number of its components.
The liquids compatible with 8424 must be at low
viscosity, namely: Diesel fuel, Water, Water/urea
solution, Kerosene, Windscreen, Petrol.
