The MD-S270L series wireless digital level gauge is a low-power wireless transmission level gauge independently developed by Shanghai Mingkong, which can be powered by batteries.
This series of products is a liquid level measuring instrument designed based on the principle of static pressure on the basis of wireless digital pressure gauges, with multiple wireless transmission methods including 4G/LORa/NB iot.
This series of products adopts explosion-proof cast aluminum shell and 304 stainless steel joint, built-in high-precision liquid level sensor, equipped with LCD display screen, polyurethane cable and immersion liquid level probe, easy and reliable installation, and good waterproof performance.
This series of products has multiple auxiliary functions such as reset, backlight, power on/off, unit switching, and low liquid level alarm.
This series of products all have functions such as adjustable sensor acquisition speed, adjustable transmission frequency, adjustable high and low pressure alarm values, and real-time pressure alarm.
MD-S270L-G is a wireless digital liquid level gauge with 4G transmission. With China Mobile's mature 4G network, it can upload the water level of the on-site water tank or reservoir
To the cloud. Users can match IP addresses and other common parameters on-site or remotely.
MD-S270L-LR is a wireless digital liquid level gauge for LORa transmission, which is used in conjunction with LORa gateway. It has the advantages of low power consumption, long transmission distance, strong signal penetration, and self-organizing network.
MD-S270L-NB is a wireless digital liquid level gauge with NB iot transmission technology, which has the advantages of low power consumption, high transmission efficiency, and low cost.
This series of products has passed CE certification and intrinsic safety explosion-proof certification.
