Flow limits

In the meter’s working area, i.e. from min. cut-off till far above qs, there is a linear connection between the water
volume flowing through and the water flow measured.

In practice the highest possible water flow through the meter will be limited by the pressure of the installation
pressure or of cavitation that has arisen as a consequence of a too low back pressure.

If the flow is lower than min. cut off or reversed,

MULTICAL

®

401 will not measure any flow.

The upper flow limit q

s

is according to EN 1434 the highest flow, at which the flow sensor may operate for short

periods of time (

<

1 h/day,

<

200 h/year) without exceeding the max. permissible error. MULTICAL

®

401

has no

functional limitations during this period, when the meter operates over q

p

. However, please note that high flow

velocities may cause cavitation, especially at low static pressures.

q

p

3…15 m³/h

Triangle

The sound path covers the
measuring pipe in a triangle and
is sent round from the
transducers in the measuring
pipe via reflectors.

q

p

0.6…1.5 m³/h

Parallel

The sound path is parallel to
the measuring pipe and is
sent from the transducers via
reflectors.
