Array measuring Option VN

Average velocity in a flow channel is calculated as

per

DIN EN 12599

, namely by performing measuring

operations at particular array points in a cross-sec-

tion vertical to the pipe axis (see Manual 3.5.5). To

ensure that all individual values are logged in

standardized form a menu combination

Array

measuring

specially conceived for flow sensors

(m/s) is provided.

the 1st menu

the channel data and a measuring point designation are en-

tered. If a memory connector with SD-card is available, channel data already

acquired selected with

PROG

FIRST

NEXT

and can be loaded from an existing

file by means of

LOAD

Channel type with k-factor,

dimensions

, and

number of holes

are all prescribed by the chan-

nel; the

number of measuring depths

and

grav-

ity lines are used to calculate

the actual meas-

uring depths

(3.5.5).

Entering the averaging duration in seconds ensures uniform data acquisition per

point by averaging over a fixed time. If the averaging duration is deleted, its start

and stop are prescribed by the measuring duration.

To select the

2nd menu

press key(s)

►

F >

It is thus possible to acquire all measuring points

from the 1st hole right through to the last hole at

all precalculated depths. The measuring operation

is initiated by pressing the

<MEAS>

key; then each

point is acquired one after the other

with

<START>

key. Any point can subsequently be

reselected for correction by means of the cursor

keys.
