Description
1
Unit
Unit of the connected linear differential
pressure transmitter
2
Measuring range start
The start of the measuring range is defined
with this parameter.
3
Measuring range end
The end of the measuring range is defined
with this parameter.
4
Zero-point window
0.00 … 25.00 %
This parameter is used to set a range
around zero at which the measured value
is set to zero.

See section a) Characteristic curve: linear [Level 5].
NOTICE! The measuring range start must always be set to zero in the flow
measurement. Other values will lead to an error message.

System parameter:
Differential pressure of the differential pres-
sure sensor at the value defined by the
parameter
<Volume flow>

System parameter:
Flow rate at the value defined by the para-
meter
<dP Differential pressure>
.
The square rooted function (measuring range start and end) is automatically
calculated from the system parameters.
NOTICE! The value zero is not allowed for the parameter dP Differential
pressure sensor and leads to an error message.
