Application Areas:
- Accurate monitoring of ultrapure water (WFI) flow in pharmaceutical companies
- Installation of flow meters without the need for production downtime or modification of existing piping
- High-precision flow measurement solutions that meet stringent industry hygiene standards
Background:
With the pharmaceutical industry’s continuous pursuit of quality and production efficiency, Kanghong Pharmaceutical is dedicated to the production of biologics and injectable drugs at its Chengdu facility. The company focuses on meeting strict quality standards, especially in the sterile production processes where ultrapure water (WFI) forms the foundation of every batch of medication. To ensure precise control over the production process, Kanghong needed to ensure that its WFI flow measurement system not only met accuracy requirements but also complied with the industry’s hygiene and safety standards.
Measurement Requirements:
WFI (Water for Injection) is a crucial basic liquid in the production process, requiring extremely high purity and low conductivity. To ensure precise control of water flow during production, Kanghong needed a flow meter that could continuously monitor the WFI flow. This system must be highly reliable and stable, capable of adapting to changing production conditions without contaminating or affecting the production environment.
The traditional flow meters previously used faced challenges with accuracy errors and pipe contamination, especially in pharmaceutical processes with strict hygiene requirements. To overcome these issues, the company decided to adopt a new, non-contact flow measurement technology.
Solution:
To meet the strict hygiene requirements and high precision demands, Kanghong chose an advanced clamp-on ultrasonic flow meter. This flow meter uses non-contact measurement technology and can be directly installed on the outside of pipes, eliminating the need for modifications to the existing piping system. The flow meter employs high-frequency ultrasonic technology to precisely calculate the flow rate by measuring changes in the ultrasonic signal as the fluid passes through the pipe, avoiding the contamination risks associated with traditional contact flow meters.
The clamp-on flow meter is especially suitable for monitoring the flow of ultrapure water (WFI). Its high precision and stability make it an ideal choice, capable of providing real-time flow data in sterile production environments while meeting the pharmaceutical industry’s equipment hygiene standards.
User Benefits:
By adopting the clamp-on ultrasonic flow meter, Kanghong significantly improved the accuracy of WFI flow monitoring and avoided the hygiene risks associated with traditional flow meters. The installation of the flow meter did not require any production downtime and could be fitted onto the existing piping system, eliminating the need for complex pipe modifications.
Since the device is non-contact, the customer does not need to worry about leakage or contamination issues caused by seals or connection points. Additionally, the intelligent design of the flow meter allows for quick startup without the need for additional technical training, meaning operators can immediately begin using the system. The dual-sensor design of the flow meter reduces installation space requirements, shortens installation time and costs, and improves overall production efficiency.
