Operating Instructions

Technical data Micropilot FWR30
24 Endress+Hauser
• No signals are analyzed within the blocking distance (BD)
For this reason, the blocking distance can be used to suppress interference signals (e.g.
from condensate) near the antenna
• Factory setting: 0 mm
• The blocking distance (BD) can be defined in the cloud or set automatically
The setting is made in the blocking distance parameter
The following formula is used for the automatic setting:
Empty tank - full tank - 100 mm (3.94 in) = blocking distance (min. 0 mm)
14.1.5 Operable flow range
The sensitivity of the sensor can be configured using a "sensitivity parameter" (high,
medium, low).
14.2 Output
14.2.1 Output signal
Cellular radio NB-IoT, LTE-M with 2G fallback
• 2G GPRS/EDGE
• 4G LTE-M1 (LTE Cat-M1)
• 4G LTE-NB1 (NB-IoT)
The cellular radio signal is selected automatically by the device. The selection depends on
availability. The priority is 4G (LTE-M1 or LTE-NB1). If neither of the two cellular radio
signals is available, the 2G (GPRS or EDGE) cellular radio signal is selected.
Transmission interval
15 minutes to 24 hours.
The battery life depends on the transmission interval.
14.2.2 Protocol-specific data
The FWR30 uses
• internet protocol TCP/IP and the secure transport layer TLS (v1.2)
• application layer protocol HTTPS
14.3 Environment
14.3.1 Ambient temperature range
–20 to +60 °C (–4 to +140 °F)
14.3.2 Storage temperature
–20 to +60 °C (–4 to +140 °F)
Battery discharge is at its lowest if the battery is stored at temperatures from
0 to +30 °C (+32 to +86 °F).
14.3.3 Humidity
0 to 95%
