Low-power remote water level gauge
The remote liquid level gauge does not require power supply and can remotely measure the water level. The product is equipped with a high - energy lithium battery pack, and the standby current is only 0.2mA. When using the "ultrasonic + submersible" dual liquid level gauge, the battery operating time exceeds 5 years, which greatly reduces the maintenance cost of users. It can also be connected to a waterproof camera to capture on - site pictures. The product has a powerful communication function, integrating 2G/4G communication modules. Even with a low - cost IoT card, the data can be reported to four central stations and eight primary and standby channels simultaneously. It also has functions such as automatic switching of primary and standby channels, additional alarm reporting, and SMS sending to ensure stable and reliable communication and no data loss. The product's fuselage has a waterproof rating of IP68, and the shell is made of anti - aging and corrosion - resistant polymer materials. It is especially suitable for applications such as on - line water level measurement in working manholes, pipelines, enclosed spaces, and rivers in remote areas. Intelligent echo signal processing technology ensures the stability and reliability of measurement values. The water level sensor is pre - calibrated before leaving the factory, and the factory calibration coefficient can be restored at any time. The built-in battery pack can provide power for more than 5 years (collect and report once per hour). Seamlessly switch between 2G and 4G according to the wireless intensity to ensure stable communication. It can be connected to a camera to capture the scene picture The protection level reaches IP68, and the components are fully potted, so they will not be damaged even if immersed in water for a long time.
