22 == 1.1 What is SW3L-NB NB-IoT Flow Sensor ==
23
24
25 The Dragino SW3L-NB is a (% style="color:blue" %)**NB-IoT Flow Sensor**(%%). It detects water flow volume and uplink to IoT server via NB-IoT network. User can use this to (% style="color:blue" %)**monitor the water usage for buildings**.
26
27 The SW3L-NB will send water flow volume every 20 minutes. It can also detect the (% style="color:blue" %)**water flow status and send Alarm**(%%), to avoid the waste for water usage such as broken toilet case.
28
29 SW3L-NB is designed for both indoor and outdoor use. It has a weatherproof enclosure and industrial level battery to (% style="color:blue" %)**work in low to high temperatures**.
30
31 SW3L-NB supports different uplink methods including (% style="color:blue" %)**MQTT, MQTTs, UDP & TCP**(%%) for different application requirement, and support uplinks to various IoT Servers.
32
33 SW3L-NB (% style="color:blue" %)**supports BLE configure **(%%)and(% style="color:blue" %)** OTA update**(%%) which make user easy to use.
34
35 SW3L-NB is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery**(%%), it is designed for long-term use up to several years.
36
37 SW3L-NB has optional built-in SIM card and default IoT server connection version. Which makes it works with simple configuration.

675
676 2) Does it change with temperature, temperature will affect its measurement
