Description
PL701 wireless level sensor is an intelligent instrument with wireless communication function & SUPER LOW power consumption. with a advanced industrial MCU and a high quality pressure sensor, it integrates the GPRS network to realize the wireless transmission between filed equipment and server. This gauge will report the pressure 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.
Based on widely covered GPRS network, the PT701wireless pressure logger could detect real-time data of many monitoring sites INDEPENDENTLY within a large areas like detection for wellhead of coal plants, pipe network pressure of tap-water, water level of head-tank and environmental parameters of large scale and hydro-logical detection etc.
It is mainly used in fields like petroleum, coal, tap water and industrial automation controlling etc.
