List of determined measurement values

Sensor values

The following measurement values are recorded via the Modbus client interface (RS485) and the 2 universal inputs. Depending on the sensor type (distance or pressure) selected during configuration, the measured value is interpreted either as a distance value in metres or as a pressure value in bar.

Modbus measurement value 1-3 [m] or [bar]
Measurement value read directly from the Modbus sensor
Universal input raw value 1-2 [mA]
Raw value recorded on the universal input
Universal input measurement value 1-2 [m] or [bar]
Measurement value calculated from the raw value (mA), taking scaling, offset and trimming into account

 

Calculated level values

The following level values are calculated from the sensor values, taking the mounting height into account:

Sub level 1-2 [m]
Calculated level taking mouning height into account

If "Absolute pressure compensated" mode is selected in the configuration, two pressure sensors are required to calculate the level. Both the atmospheric pressure and the pressure within the medium are required.

Main level [mV]
Sub level that provides the higher-quality measurement at the time of recording.

A threshold value can be set to determine which sub level should be used for the respective section of the level range to be measured. This allows you to combine the advantages of both measurement methods when using a hydrostatic sensor in conjunction with a radar sensor. If the sensor used for the active sub level fails, the system automatically switches to the other sub level, regardless of the threshold value. As both sub levels are continuously recorded in parallel, there is no interruption to the recorded main water level data.

 

Internal measurement values

In addition to the measurement values provided by the external sensors and the calculated level values, the following internal measurement values are determined:

GSM [dBm]
Mobile network signal strength
Input Voltage [V]
Voltage provided by the PV module
Battery Voltage [V]
Current voltage of the rechargeable buffer battery
State of Charge [%]
State of Charge of the rechargeable buffer battery
Internal Temperature [°C]
Internal device temperature of the Lizzox Pure Flood
Internal Humidity [%]
Humidity in the housing of the Lizzox Pure Flood
Load [mAs]
Energy consumption between tow recordings
Runtime [Days]
Estimated remaining device lifetime with unchanged configuration
Output Vsens
Sensor supply voltage saved in the configuration at the time of measurement
Output Ext3V3
