MD-L271 wireless level gauge (waterproof type) Introduction
The MD-L271 series of wireless level gauges was developed to meet the needs of the rainwater network/sewage pipe network for water level monitoring. It features high waterproof rating, built-in antenna and built-in lithium battery.
This series of products is a liquid level measuring instrument with a variety of wireless transmission methods, including GPRS / LORa / NB-iot multiple transmission options.
Built-in high-precision liquid level sensor, equipped with LCD liquid crystal display, equipped with polyurethane cable and input liquid level probe, easy to install and reliable, waterproof performance.
This series of products has a variety of auxiliary functions such as low level alarm, liquid level fluctuation alarm, Bluetooth configuration.
The MD-L271 G is a wireless digital level gauge for GPRS transmission. With the mature GPRS network of China Mobile, the water level of the site or the water level of the reservoir is uploaded to the cloud. Users can match IP addresses and other general parameters either on-site or remotely.
The MD-L270L is a wireless digital level gauge for LORA transmission. It is used with the LORA gateway and has the advantages of low power consumption, long transmission distance, strong signal penetration, and self-organizing network.
The MD-L270N is a wireless digital level gauge for NB-iot transmission. It uses NB-iot technology, which has low power consumption, high transmission efficiency and low tariff.
This series of products passed the protective performance test and low temperature resistance test. Features
