FEATURE

The MD-S275L Smart Wireless Digital Level Transmitter is a battery-powered, wirelessly communicating outdoor digital level meter. It features IP67 protection and can be used long-term in outdoor pressure pipelines. Powered by a lithium battery (with an external power version available), combined with low-power design, it can meet 2~3 years of normal battery life requirements. It supports mainstream wireless communication methods including 4G, NB, LoRa, and LoRaWAN. Parameters can be configured and firmware upgraded via on-site Bluetooth APP and the remote 'DaLanMao' (Big Lazy Cat) platform, reducing difficulty for construction and maintenance personnel. The mode of scheduled data upload + immediate alarm data upload ensures higher alarm timeliness.
