Last week, Mr. Wang, the general manager of a subway infrastructure project in City A in southern China, made a special trip to the AIMOLI factory for an on-site inspection. They wanted to purchase our AIMOLI AML920 groundwater velocity and direction meter<\/a>.<\/p>\n\n\n\n

In southern China, AIMOLI already has numerous groundwater monitoring<\/a> application cases in projects such as subways, railways, and karst caves. Mr. Wang was attracted by our subway project in City B.<\/strong><\/p>\n\n\n\n

The difficulties Mr. Wang is facing are very similar to those of the subway project in City B: the surrounding geographical factors such as mountains and seawater create a very complex groundwater flow field, and it is also necessary to monitor the impact force of post-rain runoff and the intrusion pressure of seawater.<\/p>\n\n\n\n

If traditional equipment is used to monitor groundwater velocity and direction, there are three main problems:<\/strong><\/p>\n\n\n\n

    \n
  1. High workload and high cost. Traditional groundwater velocity and direction measurement generally relies on methods such as multi-hole tests, tracer dosing, and water level difference calculations, which are labor-intensive, costly in terms of manpower, and time-consuming.<\/li>\n<\/ol>\n\n\n\n

    Our AIMOLI AML920 groundwater velocity and direction meter eliminates the need for multiple wells, acquiring three-dimensional vector data of groundwater from a single well. <\/strong>This significantly reduces costs for our clients, a feat unmatched by competitors.<\/p>\n\n\n\n

      \n
    1. High difficulty and inaccuracy. Traditional groundwater velocity and direction measurement typically employs thermal pulse and ordinary particle tracer methods. The thermal pulse method is significantly affected by water pressure, limiting its application to water levels below 100 meters, and suffers from inaccuracies. Ordinary particle tracer methods are only suitable for water bodies that are not excessively clear or turbid. Furthermore, global competitors in traditional groundwater velocity and direction measurement are still largely reliant on two-dimensional planar data.<\/li>\n<\/ol>\n\n\n\n

      However, the surrounding geological conditions of this subway project, including mountains and seawater, create a harsh environment and a highly complex groundwater flow field. The varying clarity and turbidity of the groundwater directly impact the accuracy of velocity and direction measurements, making traditional methods prone to inaccuracies.<\/p>\n\n\n\n

      Our AIMOLI AML groundwater velocity and direction meter employs a three-dimensional vector algorithm, a generation ahead of traditional two-dimensional planar data.<\/strong><\/p>\n\n\n\n

      Furthermore, we utilize particle tracer measurement technology, ensuring accurate measurements regardless of the groundwater’s clarity or turbidity, and allowing visualization of water flow to guarantee the accuracy of the assessment data.<\/p>\n\n\n\n

      More importantly, our AML920 groundwater velocity and direction meter boasts an IP68 protection rating, a 316 series stainless steel probe, and corrosion resistance, enabling continuous operation in harsh environments. <\/strong>It provides real-time monitoring of the impact of engineering projects on the groundwater flow field, transmitting data via BeiDou + 4G dual-mode for real-time project tracking.<\/p>\n\n\n\n

      Even the Ministry of Justice and the Ministry of Ecology and Environment have listed our AIMOLI AML920 groundwater velocity and direction meter as an essential instrument for judicial assessment of soil and groundwater environmental damage.<\/p>\n\n\n\n

        \n
      1. Limited data, insufficient to meet requirements. Traditional groundwater velocity and direction meters provide limited data, while Mr. Wang’s subway project in City A has more stringent requirements, demanding more data, which is insufficient to meet the needs of traditional meters. Conducting additional measurements would incur significant time and financial costs.<\/li>\n<\/ol>\n\n\n\n

        Our AIMOLI AML920 groundwater velocity and direction meter comes standard with six parameters: velocity, direction, water level, water temperature, top-down view, and 360\u00b0 surround view of the well. It can also be expanded with parameters such as pH, conductivity, dissolved oxygen, turbidity, oxidation-reduction potential, qualitative analysis of characteristic pollutants, and identification of new pollutants including nitrogen oxides, organic matter, and heavy metals in groundwater. Customization is also available for special needs.<\/p>\n\n\n\n

        We can do almost everything Mr. Wang has thought of, and even things he hasn’t thought of.<\/strong><\/p>\n\n\n\n

        After visiting AIMOLI, Mr. Wang said that he had visited three manufacturers, but only the AIMOLI AML920 groundwater velocity and direction meter gave him the most confidence.<\/p>\n\n\n\n

        AIMOLI environmental meters, accurate to the point that competitors are worried!<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"
