MD-L270 wireless level gauge (powered by lithium battery) Introduction
The MD-L270 series wireless digital level gauge is a low-power wireless transmission level gauge independently developed by Shanghai Ming Control. It can be powered by battery or dual power supply + battery.
This series of products is based on the wireless digital pressure gauge, using a static pressure principle design, a liquid level measuring instrument with a variety of wireless transmission methods, including GPRS / LORa / NB-iot multiple transmission options .
This series of products adopt explosion-proof cast aluminum casing and 304 stainless steel joints, built-in high-precision liquid level sensor, LCD liquid crystal display, equipped with polyurethane cable and input liquid level probe, which is convenient and reliable to install and has good waterproof performance.
This series of products has a variety of auxiliary functions such as clearing, backlighting, switching, unit switching, low level alarm and so on.
This series of products have the sensor acquisition speed can be set, the frequency can be set, the high and low voltage alarm value can be set, the instant pressure alarm and other functions.
MD-L270 G is a wireless digital liquid level meter for GPRS transmission. With the mature GPRS network of China Mobile, the water level of the tank or the water level of the reservoir will be 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 has passed CE certification and intrinsically safe explosion-proof certification. Feature
