Micropilot FWR30 Technical data
Hauser 21
14 Technical data
14.1 Input
14.1.1 Measured variable
Measured process variables
• Level: 0 to 15 m (0 to 49 ft)
• Ambient temperature: –20 to +60 °C (–4 to +140 °F) with an accuracy of ± 2 °C (4 °F)
• Position: Angle of device to the horizontal
Range: 0 to 90°
14.1.2 Measuring range
0 to 15 m (0 to 49 ft)
Level in mm = tank empty - distance to level surface
Level in % = (tank empty - distance to level surface / tank full ⋅ 100 %
14.1.3 Blocking distance
Factory setting: 0
14.1.4 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
• 1 hour to 24 hours
• 15-minute interval possible (shorter intervals affect the battery life)
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
