Flow measurement is a critical parameter in many processes using gases or liquids, particularly where safety is paramount due to the flow rate or type of fluid. It is also essential to measure flow where it impacts the quality of the final product; the right fluid must be at the correct point in the process at the right time.
Flow meters are the solution employed by the processing industry for flow measurement, and there is a whole range of devices on the market, each designed with a specific application in mind. Unfortunately, many of the available flow meters also have drawbacks. The FLOWave flow meter from Bürkert overcomes many of these drawbacks. We take a closer look at the advantages of Bürkert FLOWave flow meters and how they are being used across the industry.
What is the Bürkert FLOWave, and how does it work?
The innovative flow meter from Bürkert uses technology developed for other industries, such as mobile phones, geophysics and televisions. The Bürkert FLOWave Flowmeter uses the patented Surface Acoustic Waves (SAW) technology, which enables a sensor to measure mass and mechanical properties. This flow measurement technique is based on wave propagation, similar to that seen in seismic activity, whereby they start from a single point and spread along a surface of a solid material.
Designed for use with liquid media, the FLOWave flow meter can be used regardless of whether fluids are immobile, flowing quickly, or are seeing variable flow rates. The measurement of volume flow is accurate to a precision of ±0.4% of the measured valve. As well as flow measurement, the Bürkert FLOWave also measures temperature, reducing the need for an additional sensor in a PUR system.
Advantages of the Bürkert FLOWave
The key advantage of the FLOWave flow meter is that because of the SAW process employed as the flow measurement technique; the sensors are placed on the outside of the measurement tube. This means that there are no installed fittings or constrictions inside the tube where the liquid passes through, as well as no empty spaces in the measurement tube. Additionally, no contact is made between the sensor elements and the medium, so that the liquid cannot impact the sensors in any way other than that intended, and the sensor elements will not contaminate the liquid. The Bürkert FLOWave will be identical to every other straight pipe within the system, and the internal finish can be made to match those of the rest of the system to ensure consistency. The overall effect of these design features is that the Bürkert FLOWave is incredibly hygienic, perfect for food and drink or pharmaceutical applications. The key benefits of the design of the Bürkert FLOWave are:
- It is more hygienic than other flow measurement options
- It does not interfere with critical cleaning processes, including CIP and SIP
- It doesn’t create pressure drops within the system
- It can be mounted in any position, horizontal or vertical
- It consumes much less energy than other flowmeters
- It provides temperature readings as well as volumetric flow measurement
- It is easy to install, and weighing only 4kg can be done by an individual
The FLOWave flow meter from Bürkert is game-changing, particularly in industries where accuracy is essential, and cleanliness is critical. An ideal solution for pharmaceutical, food, drink and cosmetic sectors, this flow measurement solution is not only ultra-hygienic but enables complete connectivity through digital interfaces.
