Bronkhorst High-Tech BV the leaders in Mass Flow Meter / Mass Flow Controller technology for gases and liquids, Pressure Controllers and Evaporation Systems.
A few years ago, Bronkhorst expanded its portfolio of liquid flow meters and controllers with a range of ultrasonic flow meters. We interviewed Erwin Eekelder, Product Manager, and Jethro Molenaar, Area Sales Manager at Bronkhorst Nederland, to review the various scenarios in which our ES-FLOW ultrasonic flow meter is now being used for measuring and dosing small quantities of fluids.
Nowadays, the ES-FLOW flow meter is used in many different industries. Our main customer markets are the food, beverage, pharmaceutical, analytics and chemical markets. In this blog, Erwin and Jethro share the top 3 applications for our ultrasonic flow meter.
We developed our ultrasonic flow meter series to allow low volumes – between 2 and 1500 ml/min – to be measured and controlled with high precision, high linearity and low pressure loss. This is achieved by using ultrasonic sound waves in a sensor with a small tube diameter.
We discovered that users prefer this ultrasonic flow meter over other measurement and control technologies because of the following features:
Our goal is to create a highly accurate, liquid independent line of flow meters meeting the highest hygienic standards to serve the needs of our customers,
expecially for applications were low flow solutions are important.
One of our customers in the pharma industry has combined 16 ultrasonic flow meters with pumps. Jethro: 'In this particular application, our ES-FLOW flow meter is used in research into new medicines. The fact that this flow meter is fluid independent and can directly control a pump, made it very useful for dosing the many different fluids being used. While it was being installed, we were asked whether the read-out display could perhaps be positioned vertically. This prompted the development of a swivel display.'
One of our customers in the confectionery market asked Jethro’s support for a dosing solution to dose flavours and fragrances. The idea was to use the ultrasonic flow meter to control a plunger pump and to dose the natural flavours and fragrances.
When combining the flow meter with a plunger pump, higher accuracy and repeatability can be achieved and this results in less waste of the - often expensive - flavours and fragrances during the process. This way, you will get a more consistent quality and fewer rejects, which will reduce your raw material costs.
This customer case, together with similar ones, taught us the importance of having a flow meter meeting the highest hygienic standards. The ES-FLOW design is based on a straight tube with no dead volume, which makes this flow meter suitable for hygienic applications. Recently we received the 3-A authorisation for this flow meter.
High velocity oxy fuel (HVOF) coatings involve the vaporisation and mixing of a fuel with oxygen within the combustion area. The mixture is ignited under controlled temperatures and pressures, producing a flame with supersonic speed. Substances are then injected into this flame and propelled towards the substrate to form the coating. This ensures materials even better to withstand high temperatures, erosion, wear and other conditions to which they are exposed.
In this application, an ultrasonic flow meter can be used to ensure a highly consistent kerosene flow during the process. Even though when aluminium particles are included, it does not have to interfere the performance of the ES-FLOW.
Erwin: “At the moment we are working on further expansion of the product line by adding more models with lower- and higher flow ranges. Besides that, we are working on a design without a display.”
Jethro: “I think every fluid application is different. However, with the extensive product live we have – thermal, Coriolis and ultrasonic flow meters – we can offer the customer a solution for practically any scenario. We can customize it completely!''
