Webinar - Improving Safety in Pharma Applications

Join Burkert and Pharmaceutical Manufacturing Magazine for this pharmaceutical application focused webinar - Available Now: On-Demand


This informative webinar focuses on applications within the pharmaceutical industry such as WFI (water for injection) and CIP (clean in place) processes. Practical examples will show how the SAW technology can be used to gain filling time, improve quality and reduce maintenance efforts.

The audience will get to know how this new technology meets the highest hygienic standards. Since there is no sensor element in the tube, this design guarantees that the liquid is not contaminated and the device supports hygienic cleaning processes. In addition, the flow sensor is able to measure several parameters (i.e. flow, temperature, density of the liquid) and detect any bubbles in the liquid at the same time. Best practice examples from our customers in the pharmaceutical industry will show participants how they could use such a new technology to improve the safety in their own production.

We will also introduce a new flow measurement technology that improves the safety of flow measurement in the pharma industry. Compared to conventional solutions the SAW (Surface Acoustic Wave) technology offers very precise measurements and highest levels of hygiene to improve the safety of the production, reducing time and space needed for installation and measuring several parameters at the same time.

Q&A Responses from the Improving safety in pharmaceutical production with hygienic flow measurement Webinar event:

Will there be a remote display?

For both FLOWave “L” (Control Head SE98) and FLOWave “S” (Control Head SE91), we currently do not have remote device versions.  With that said, Burkert sells a variety of transmitters and controllers which can serve as a remote display.

Along those same lines, Burkert offers an optional Wi-Fi module for FLOWave, Type ME31, which would allow for wireless transmission to router via IP address for remote monitoring


What is the turndown ration (min/max)?

Recommendations for minimum and maximum flow have been developed for each size based upon target flow velocities.  Refer to Section 5.2 on page 20 of the Type 8098 Datasheet (


Can FLOWave be used for Clean Steam?

Unfortunately, no.  FLOWave is only effective at measuring flow of homogenous liquids. 

With that said, FLOWave would be perfect for measuring the flow and conductivity (calculated internally) of the incoming feed water (i.e. WFI, PW)


Will there be FLOWave’s for smaller sizes?

FLOWave is currently available in sizes ¾” (DN15), 1” (DN25), 1-1/2” (DN40) and 2” (DN50)

Burkert recently launched sizes 3/8” (DN8) and ½”, with manufacturing ramping up to full capacity by Q1-2021. 

Larger sizes 2-1/2” (DN65) and 3” (DN80) will be launched prior to end of 2020. 


Can SAW Technology be used for single-use flow measurement applications (multiple questions on SUT)?

While a single use (disposable) version of FLOWave has not been developed, FLOWave can absolutely be used in single use systems, although it will require CIP / SIP as would with any other stainless steel component.


Can FLOWave measure / calculate “true” density (not just the density factor)?

No, FLOWave does not provide a true, mass-based density of the fluidic medium.  The Density Factor (dimensionless) is used to detect minute changes in the concentration of the fluid.  This is why FLOWave is perfectly suited for applications such as Clean-in-Place.

The good news is that Burkert is developing a true density, or mass-based FLOWave device, expected sometime in 2021.


Can FLOWave handle two-phase flow?  Vapor-liquid and/or Liquid-Liquid?

Unfortunately, no.  FLOWave is only effective at measuring flow of homogenous liquids with minimal entrapped gas. 

How susceptible is FLOWave to vibration near pump discharge, and the introduction of bubbles?

In terms of measurement repeatability and accuracy, FLOWave is not impacted by vibration in piping systems.  Obviously, any mechanical vibration will have negative long term effects on any piece of equipment it impacts.  

In relation to entrapped air (i.e. bubbles), the higher the amount of bubbles the larger impact to the measurement accuracy of FLOWave.  On a positive note, this is also why FLOWave is very good at detecting entrapped air or bubbles as a result of cavitation and poor flow conditions. 


What are the advantages of FLOWave compared to conventional Doppler ultrasonic flow meters?

The mechanical design of the FLOWave sensor element / housing – straight, full-bore flow path with zero sensors or components in contact with the fluid – is the most hygienic design on the market today.  Other flow sensors, such as ultrasonic types, utilize sensing elements in contact with the fluidic medium (in the flow path) resulting in pressure drop, flow restriction and possibility of contamination.  In terms of clamp-on ultrasonic flow meters, although not contacting the fluid, the potential for damage and/or misalignment given the location on the outside of the pipe poses a risk of inaccurate measurements. 

In terms of electronics & automation – FLOWave offers significant advantages in comparison to other brands.  These advantages include:

  • Industry 4.0 “smart” device for decentralized control on a device-to-device level
  • Intuitive user-friendly interface – multi-position backlit LED provides the user full access, setup and diagnostic capabilities at the device
  • Available with Industrial Ethernet communication capability – Ethernet/IP, PROFINET and Modbus TCP  
  • IP65/67 Rating, meets all CE and PED requirements, UL listed (USA & Canada), Certification of Compliance ASME BPE, ATEX available
