36.1.7 Stability
The stability parameter defines the period the transmitter bridges values without having valid
measurement events (e.g. in case of invalid level or flow velocity readings) available.
During this period the NivuFlow Mobile operates using the latest valid reading. If the specified
period is exceeded without detecting a correct value the transmitter goes back to reading “0”
considering the damping set. The transmitter does not store the values.
Input the value in steps of one second.
Default setting : 30 s
36.2 Setting Parameters in Menu h-Sensors
After setting the measurement place parameters, the level sensor(s) shall be defined and the
according measurement range(s) need to be determined.
The level sensor parameters can be set in the >h-sensors< submenu.
36.2.1 h-Sensor types
Fig. 36-7 Selection level sensor settings
You can find a choice of level sensors behind the button >h-Sensor types<.

Open parameter >h-Sensor types< and select the type of sensor connected to the
transmitter.
For the very most applications it is sufficient to select a level sensor.

In case of using more than one level sensor (e.g. i-Sensor and 2-wire level) check one
box for each sensor.
Sensor connected?
After finishing the parameter settings the missing or faulty programmed sensors are detect-
ed and the instrument issues an error message.
The number of the selected sensors is equal to the number of the individual level measure-
ment sensors over the entire measurement cross section. Only one level sensor can provide
a valid reading per measurement. The transmitter does not accept faulty and not reasonable
combinations.
A maximum of three different level sensors can be selected.
Adjust the sensor measurement ranges underneath the channel graph.
