On September 12, 2025, the UK Municipal Sanitation Group completed commissioning of its Jujea DN40 turbine flowmeters, which were mass-produced for its sprinkler trucks, and officially entered daily operation. This flowmeter, combining high-precision measurement, compact size, and easy operation, accurately solves the challenge of calculating daily water consumption on sprinkler trucks. Its wide-temperature design and durable construction, adapted to the UK's changing climate, make it a preferred
solution for mobile water metering in the municipal sanitation sector. As a company specializing in the research and development and manufacturing of flow metering equipment, Jujea specializes in manufacturing high-quality flow
products for flow measurement and control, offering customized products and comprehensive service.
1. Pain Points in UK Municipal Water Sprinkler Metering: The Dual Demands of Mobile Operations and Precise Management
1.1 Understanding the Customer's Core Needs and Solving Their Flow Measurement Problems
This UK municipal sanitation group is responsible for road cleaning and landscaping irrigation in London and surrounding areas. Its core needs focused on:
Accurately measure each sprinkler's daily environmental water consumption to enable digital management of water resource consumption, in line with the UK municipal "water conservation and emission reduction" policy;
The equipment needed to be adaptable to the bumpy conditions of mobile sprinkler trucks, be compact and space-saving, and easy to install, without compromising daily operational efficiency;
-
Withstand the UK's complex climate (summer highs of 32°C, winter lows of -10°C, and frequent rain and humidity) and the high-pressure environment of the vehicle's pipes, ensuring stable operation year-round.
Examining the operating conditions, the sprinkler truck's main pipe is DN40 in diameter and is fully supplied with environmental water (containing a small amount of road debris and non-corrosive). The traditional metering method previously used had significant shortcomings and could not meet the needs of refined management. 1.2 Traditional flow meters have low adaptability and cannot achieve both accuracy and durability.
Prior to the collaboration, the group had trialed two traditional metering solutions, both of which were eliminated due to insufficient performance:
-
Mechanical water meters: These were bulky (over 15cm in diameter) and easily damaged by vibration when installed in the main pipe beneath the sprinkler truck. Within a month, 12 meters experienced meter jamming, increasing the metering error from ±3% to ±12%. Furthermore, they lacked a function to reset accumulated flow, requiring manual recording of daily statistics.
-
Conventional electronic flow meters: Their accuracy was only ±2%, failing to meet the municipal standard of ±1%. Furthermore, they only supported AC220V power supply, requiring the installation of an additional on-board inverter, which not only increased costs but also posed a risk of circuit failure. During the trial, inverter failures caused three sprinkler trucks to stop operating. "The municipal government has strict requirements for data accuracy. Traditional equipment is either inaccurate or not durable, making water consumption statistics a constant management challenge for us," the Operations Director explained during a communication. After learning about Jujea's turbine flowmeter case study on Google's independent website, he contacted us and immediately initiated a collaborative effort to address this pain point.
2.Customized Parameters and Scenario Adaptation for the DN40 Turbine Flowmeter
As a manufacturer, Jujea, leveraging its proprietary R&D production line and parametric design capabilities, customized a DN40 turbine flowmeter solution tailored to the operating conditions of sprinkler trucks. From core performance to functional design, it's precisely tailored to mobile operation scenarios:
2.1 Turbine Flowmeter: Triple Advantages of Accuracy, Durability, and Convenience
Parameter Category |
Specific specifications |
Advantages |
|
Basic measurement parameters
|
Diameter DN40, flow range 2~20m³/h (suitable for single-channel flow of sprinkler trucks), measurement accuracy ±0.5% |
Meets UK municipal ±1% measurement standards, ensuring accurate and reliable data |
Power supply and signal |
Dual power supply mode (3.6V lithium battery / DC24V), supports pulse / 4~20mA / RS485 signal output |
Adapt to the sprinkler truck's onboard power supply; RS485 signal can be connected to the platform to achieve automatic data upload
|
Installation and pressure bearing |
Flange connection (compatible with British standard pipe interface), pressure level 2.5MPa |
A single unit can be installed in 10 minutes, and its 2.5MPa pressure-bearing capacity can withstand high pressure from vehicle-mounted pipelines without the risk of leakage.
|
Material and environmental adaptation |
Valve body material: SS304 (corrosion-resistant and impact-resistant), operating temperature: -20~80℃, protection level: IP65 |
Resistant to the UK's rainy and humid environment, the SS304 material resists impurities and wear, and the wide temperature design adapts to the temperature difference between winter and summer
|
2.2 The manufacturer covers every step from R&D to delivery.
As a direct manufacturer of turbine flowmeters, Jujea's core competitiveness lies in its deep understanding of product quality and customer needs:
-
Customized R&D: Targeting the mobility of sprinkler trucks, the flowmeter's internal structure is optimized, reducing its overall volume to just one-quarter that of traditional mechanical water meters, allowing it to fit seamlessly into the confined space beneath the main pipe beneath the truck.
-
Strict quality control: The SS304 valve body utilizes a precision forging process, and the internal turbine undergoes tens of thousands of dynamic balancing tests to ensure stable metering in turbulent environments. Each unit undergoes triple testing before shipment: high pressure (2.5MPa), high and low temperature cycling (-20°C to 80°C), and waterproof immersion (IP65 standard), achieving a 100% pass rate.
3.Flow monitoring provides data-driven management, addressing the challenges of inefficient municipal operations.
Since the first batch of 30 Jujea DN40 turbine flowmeters went into operation on September 12, 2025, the municipal sanitation management efficiency has significantly improved:
Metering accuracy meets standards: After one month of operation, the error in daily water consumption statistics has remained stable within ±0.15 m³. Data is automatically uploaded to the platform via RS485 signals, eliminating the need for manual recording.
Reduced operation and maintenance costs: The SS304 material and anti-vibration design have reduced the device damage rate from 12 units per month to 0. The lithium battery power supply eliminates the cost of inverters, reducing the cost per device by 20%.
Improved policy compliance: Accurate water consumption data helped the group successfully pass the municipal government's "water conservation and emission reduction" assessment.
"Jujea's turbine flowmeter not only solves our metering problems but also meets the city's management needs," said the company's procurement manager during project acceptance. The company has already recommended Jujea products to municipal sanitation departments in other cities. IV. Jujea Leverages Manufacturer Experience to Solve Customer Problems
