Keywords: Anhui agricultural irrigation electromagnetic flow meter, JUJEA electromagnetic flow meter manufacturer, split-type flow meter for well water metering, IP68 waterproof electromagnetic flow meter
On July 8, 2025, a professional agricultural irrigation water treatment enterprise in Chuzhou, Anhui (serving nearly 10,000 mu of cultivated land) announced that all 60 electromagnetic flow meters covering more than 20 pump stations have been commissioned and put into use. The implementation of this project not only solves the long-standing problem of "flow meter rust and scrapping in rainy seasons" faced by the enterprise, but also realizes the intelligent management of irrigation water through a customized well water metering scheme. As a flow meter manufacturer with more than 10 years of experience in the electromagnetic flow meter field, JUJEA provides a replicable metering
solution for the agricultural irrigation industry in Anhui and even the whole country with its high-performance product parameters, fully sealed design and Internet of Things (IoT) technology.
I. Pain Points of Agricultural Irrigation in Anhui: Well Water Metering Dilemma in Rainy Environments
1.1 Core Customer Needs and Operating Condition Characteristics
This Anhui agricultural irrigation enterprise uses underground well water as the irrigation water source, and conveys water to the surrounding cultivated land through more than 20 pump stations. The water transmission pipeline of a single pump station is 2 kilometers long, which needs to meet the stable water supply demand of 500 m³ per hour. Due to the differences in the area of cultivated land covered by different pump stations, the pipe diameters include four specifications: DN200, DN250, DN300 and DN350, which put forward three requirements for electromagnetic flow meters: "diameter adaptability", "waterproof and anti-corrosion performance" and "metering accuracy":
Adapt to multi-diameter pipelines to ensure accurate metering under the flow rate of 500 m³/h;
Withstand the rainy summer climate in Anhui to avoid equipment damage caused by water accumulation in pump station wells;
Support remote monitoring to improve the operation and maintenance efficiency of more than 20 pump stations.
1.2 Previous Equipment Failure Cases: Limitations of Non-Customized Products
Before cooperating with JUJEA, the enterprise purchased electromagnetic flow meters of a certain brand and installed them in the pump station wells. However, since the
products were not customized for the "well water + humid water accumulation environment", serious problems occurred within just one month:
Insufficient protection level: The conventional IP65 protection cannot resist rainwater immersion. After water accumulates in the wells during the rainy season, rainwater seeps into the equipment, resulting in the complete rust and scrapping of 12 flow meters and the metering error of 23 flow meters exceeding 5%;
Poor corrosion resistance of materials: The ordinary stainless steel shell has not undergone special anti-corrosion treatment, and scales form after long-term contact with well water (containing trace minerals), which further affects the metering accuracy;
No remote monitoring: 5 pump stations once shut down at the same time due to flow meter failures, and the water consumption could only be estimated manually. Finally, the planted crops failed to germinate and grow normally, causing direct economic losses.
"When rainwater backflows and accumulates in heavy rain, the flow meters are soaked in the accumulated water. We have tried to install rain shields and apply anti-corrosion paint, but none of them can completely solve the problem," said Engineer Li, the technical director of the enterprise.
II. Solution from Water Treatment Flow Meter Manufacturer: Fully Sealed Split-Type Electromagnetic Flow Meter + Pump Station IoT System
In view of the "well water metering + humid water accumulation" working conditions of agricultural irrigation in Anhui, as a flow meter manufacturer, JUJEA has customized a combined solution of "fully sealed split-type electromagnetic flow meter + pump station IoT system" relying on its whole industrial chain advantages from core component R&D to complete machine assembly. The product parameters accurately match the customer's needs, as follows:
2.1 Core Product Parameters: Adapted to Anhui Well Water Irrigation Scenarios
| Parameter Category |
Specific Specifications |

2.2 Split-Type Design: Solving the Problem of Humid Installation Environment
The "split installation of sensor + converter" structure is adopted to specifically solve the humidity problem of pump station wells:
Sensor (including titanium electrodes and excitation coils): Installed on the pipeline in the well, in direct contact with well water. The IP68 protection and 316L stainless steel material ensure durability;
Converter (including display screen and operation panel): Installed in the dry control room of the pump station, connected to the sensor through a shielded twisted pair (with a maximum transmission distance of 100 meters);
Advantages: Prevents the converter from short-circuiting due to moisture. Staff can view data and adjust parameters without going down the well, improving the operation and maintenance efficiency by 60%.
2.3 Pump Station IoT System: Realizing Intelligent Management of More Than 20 Pump Stations
As an original factory, JUJEA has simultaneously matched the pump station IoT system for the customer, which has three core functions to meet the needs of centralized management of multiple pump stations:
Real-time monitoring: Check the real-time flow rate (e.g., 500 m³/h), cumulative water consumption and equipment temperature of more than 20 pump stations on the computer terminal/mobile APP;
Intelligent early warning: Send double alarms via SMS and APP when the flow rate exceeds 500 m³/h ±10% or equipment failure occurs;
Data traceability: Supports data storage and export to assist customers in optimizing irrigation schemes (e.g., adjusting the flow rate according to the water demand period of crops).
III. Project Implementation and Results: Long-Term Cooperation from Pilot to 60 Units
3.1 Service Advantages of the Original Factory: Full-Chain Guarantee for Project Advancement
As an original factory of electromagnetic flow meters, JUJEA provides "customization + visualization + rapid response" services from demand connection to project acceptance:
Production end: Customers can check the production progress of 60 flow meters in real time through the "visual factory system". Each piece of equipment is attached with a quality traceability QR code (which can check raw material inspection and factory test data);
Installation end: 6 technical engineers provide on-site guidance. For 3 pump stations in special locations, the installation brackets are adjusted on site to ensure accurate connection between the equipment and the 2-kilometer pipeline;
After-sales end: 24-hour response mechanism. For faults within the province, on-site maintenance is provided within 24 hours, and remote problems are troubleshooted within 1 hour.
3.2 Project Results: Triple Values of Water Saving, Cost Reduction and Efficiency Improvement
In March 2025, after the pilot installation of the first batch of 5 DN350 electromagnetic flow meters, they still operated stably after 2 moderate rains (with 0.8 meters of water accumulated in the wells), and the metering error was controlled within ±0.3%. Based on the pilot results, the customer purchased 55 more units later, realizing full coverage of more than 20 pump stations. As of July, after 3 months of use, the results are remarkable:
Water saving: Accurate metering has increased the utilization rate of irrigation water by 35%, saving about 120 m³ of water per mu of cultivated land per year;
Cost reduction: Equipment maintenance costs have been reduced by 50%, saving more than [amount omitted] in replacement/maintenance costs every year;
Efficiency improvement: The IoT system reduces the frequency of manual inspection and improves efficiency. The number of operation and maintenance personnel for more than 20 pump stations has been reduced from 8 to 3.
"JUJEA Flow Meter Manufacturer can not only produce multi-diameter flow meters quickly, but also customize waterproof schemes according to the customer's regional and rainy season working conditions, which is impossible for brands under the distributor model," Engineer Li commented during the project acceptance. "It only took 3 days to complete the protocol adaptation of the original control system, and we are very assured of such a response speed."
IV. JUJEA Flow Meter Manufacturer: Core Competitiveness of Electromagnetic Flow Meters for Agricultural Irrigation
