Introduction & Application
PL701wireless water level monitor is an intelligent instrument with wireless communication function& super low power consumption design. with a advanced industrial MCU and a high quality level sensor, it integrates the LoraWAN network to realize the wireless transmission between filed equipment and Gateday.
This gauge will report the level data regularly based on the set interval, and the customer could track all real-time and historical records remotely on WEB pages. All of the uploaded data would be saved in database automatically for the convenience of further checking. Users could log in related URL by network-connected PC or Mobile to check data and do statistics and analysis for the data, then forming a report and data graph, which is featured as visual, accurate and high-efficient.
Cooperated with LoraWAN gateway, the PL701 wireless level logger could work anywhere, and it’s widely used in applications such as,tank level, water reservoir level, river lake level and hydro-logical monitoring. It is mainly used in fields like tap-water plant and hydroelectric power plant.
