Insertion ultrasonic flowmeter
Keywords: jujea ultrasonic flowmeter, insertion flowmeter, DN500 carbon steel pipe flowmeter, water flow measurement, Brazilian flowmeter project
In the field of industrial flow measurement, large-diameter carbon steel pipes, rusty surfaces, and the need for accurate water flow data together pose a huge challenge. In October 2025, professional flowmeter manufacturer jujea, with its insertion ultrasonic flowmeter, successfully provided a customized solution for a Brazilian customer who had difficulties in measuring water flow in a DN500 carbon steel pipe, overcoming the obstacles caused by rust and ensuring measurement accuracy.
How did the Brazilian customer choose a flowmeter?
This Brazilian customer is engaged in industrial water supply and distribution. Accurate measurement of water flow in a DN500 carbon steel pipe is crucial to its production and resource management. However, several problems arose in the initial measurement attempt:
(1) Pipeline and medium characteristics
The pipe involved was DN500 and made of carbon steel. Due to time and environmental factors, the inner and outer surfaces of the pipe were rusted. The measuring medium is water, which is clear in itself, but it has to flow through this rusty pipe.
(2) Limitations of external probes Initially
The customer tried to use an external ultrasonic flowmeter probe. However, the rust on the carbon steel pipe seriously affected the transmission of ultrasonic waves. The rust layer formed an uneven and discontinuous surface, which caused ultrasonic signal scattering, irregular reflection and significant attenuation. As a result, the measurement accuracy was far from satisfactory, the error was high, and it was impossible to provide reliable flow data for production scheduling and resource allocation.
(3) Specific requirements of the project
The customer had clear and specific requirements for the flowmeter: - It should be suitable for DN500 pipes to accurately measure water flow. - The installation method should be plug-in, because the external probe was not effective due to rust. - All necessary connectors for welding to the pipe must be included. - The flowmeter should support RS485 communication using MODBUS-RTU protocol for seamless integration with the customer's existing control system. - It needs to be airlifted to Brazil to ensure timely delivery.

3. Flow measurement project implementation and results
(1) Installation and debugging
After receiving the JUJEA plug-in ultrasonic flow meter, the customer’s technical team proceeded to install it. The process went very smoothly:
First, the designated location of the DN500 carbon steel pipe was prepared and the custom-made connector was securely welded.
Then, the insertion probe was inserted into the pipe through the connector. The design of the probe ensured a tight seal to prevent water leaks.
Finally, the flow meter's transmitter was connected to the power supply and the customer's control system. JUJEA's technical support team provided remote guidance throughout the commissioning process, helping the customer set the relevant parameters and verifying the communication via RS485 using the MODBUS-RTU protocol.
(2) Significant results
Since the successful installation and commissioning of the JUJEA insertion ultrasonic flow meter, the customer has achieved significant results:
Accurate measurement: Provided the customer with reliable water flow data. The measurement data enabled the customer to optimize water use, reduce waste, and improve production efficiency.
Stable operation: Even in the rusty DN500 carbon steel pipe, the insertion probe ensured stable transmission of the ultrasonic signal. The flow meter continued to operate without measurement errors or equipment failures caused by rust on the pipe surface. - Seamless System Integration: RS485 communication using the MODBUS-RTU protocol enables flow meter data to be seamlessly integrated into the customer's control system. The customer can now monitor water flow in real time, set alarms for abnormal flow conditions, and generate detailed flow reports for analysis.
Cost-Effectiveness: By solving measurement problems with a cost-effective insertion flow meter, the customer avoided the need to replace expensive pipes or use a more complex and costly measurement system. The total cost, including the flow meter and air freight, was within the customer's budget and offered excellent value for money.
