Last month, we received a phone call from Mr. Wang, a service provider in a certain province (privacy details omitted). He wanted to conduct a survey for a provincial geological research institute to measure the groundwater velocity and flow direction within their jurisdiction.
Our communication with Mr. Wang went very smoothly. During the call, we roughly discussed the project situation, and when we sent the quotation, he immediately agreed.
At first, I didn’t know why, because usually clients would try to negotiate the price during the quotation stage. But Mr. Wang accepted it right away. Later, I found out that it was because the provincial Environmental Protection Bureau had specifically designated the use of AIMOLI’s AML920 Groundwater Velocity and Flow Direction Meter for the survey, so the service provider had to procure it according to the plan.
Due to the presence of cracks and voids in underground soil and bedrock, water flows from high-pressure areas to low-pressure areas under pressure.
During this process, fine soil particles are carried away first.
If the water pressure increases further and is sufficient to move coarser particles, seepage intensifies and larger sand and gravel are transported.
Accidents can potentially occur in this process, though in reality it is much more complex. Therefore, determining the groundwater velocity and flow direction is crucial for better accident prevention.
Our first site visit was to a wastewater treatment plant, where the monitoring well was about 40 meters deep and the water inside was quite turbid. After communicating with the on-site supervisor, we learned that they had previously contacted several other manufacturers of groundwater velocity and flow direction meters.
However, when these manufacturers arrived at the site, they all shook their heads in despair and left.
Some of their equipment had a lifting range of only 10 meters, unable to even reach the water surface, while others could only measure the mid-water layer. In such turbid conditions, their instruments simply could not work.
After reporting the situation to their superiors, they were instructed to use our AML920 Groundwater Velocity and Flow Direction Meter.
AIMOLI’s AML920 can measure well depths of up to 1,000 meters—so a mere 40-meter well is a piece of cake.
Moreover, we can measure not only the mid-water layer but also clear and turbid water layers, something competitors cannot achieve.
At the site, when our AML920 probe was lowered into the well, the movement of suspended particles in the water and the flow direction became clearly visible. Using our surface controller, we accurately calculated the water’s velocity.
Upon seeing the test data, Director Liu from the geological research institute gave us a thumbs-up and said, “AIMOLI is incredible! You are a brand that Chinese people can be proud of!”
Six Key Advantages of the AML920 Groundwater Velocity and Flow Direction Meter Compared to Leading International Brands:
- Proprietary tracer agent for measuring the velocity and flow direction of water at any turbidity level—no one has achieved this in the past three years.
- Wireless control via smartphone or tablet; imported meters only have a display, making us unmatched domestically and internationally.
- Ability to observe downward and perform 360-degree panoramic observation at a single water level—something neither imported nor domestic meters can do simultaneously.
- Special protective film prevents cross-contamination between different underground water layers, which competitors lack.
- Cables with built-in meter markings allow a single operation to complete the test, reducing the need for extra instruments and extra steps compared to competitors.
- The lifting pump allows manual and automatic switching; even a small girl can operate it, which competitors cannot achieve.
