BASIC FUNCTION o SYSTEM PARAMETER o CONFIGURATION
INSTALLATION
DIRECTION SENSOR
(6600)
Use this function to reverse the sign of the flow direction, if necessary.
! Note!
Ascertain the actual direction of fluid flow with reference to the direction indicated by
the arrow on the sensor (nameplate).
Options:
NORMAL (flow as indicated by the arrow)
INVERSE (flow opposite to direction indicated by the arrow)
Factory setting:
NORMAL
DENSITY DAMPING
(6602)
The density filter allows the sensitivity of the density measuring signal to be lowered with
respect to variations in the density of the fluid, e.g. with inhomogeneous liquids. The
damping acts on all functions and outputs of the measuring device.
User input:
max. 5-digit number, including unit: 0.00...100.00 s
Factory setting:
0.00 s
FLOW DAMPING
(6603)
Setting the filter depth of the digital filter. The sensitivity of the flow measurement signal
can be reduced with respect to interference peaks (e.g. in the event of a high solid
content, gas bubbles in the fluid etc.). The reaction time of the measuring device
increases with every increase in the filter setting. The damping acts on all functions and
outputs of the measuring device.
User input:
0...100 s
Factory setting:
Liquid: 0,00 s
Gas: 0,25 s
POSITIVE ZERO RETURN
(6605)
Use this function to interrupt evaluation of measured variables. This is necessary when a
piping system is being cleaned, for example.
This setting acts on all function and outputs of the measuring device.
Options:
OFF
ON (signal output is set to the “ZERO FLOW” value, temperature and density are still
output)
Factory setting:
OFF
