ES-FLOW™ Low-Flow Ultrasonic Flow Meters / Controllers for Liquids Ultrasonic flow meter for low flow rates The innovative ES-FLOW™ Ultrasonic Liquid Flow Meter/Controller is designed for measuring volume flow ranges between 4 and 2-1500 ml/min with high precision, high linearity and low pressure drop using Ultrasonic Wave Technology in a small bore tube. Liquids can be measured independent of fluid density, temperature and viscosity. Therefore, recalibration per fluid is unnecessary as the instrument is able to detect the actual speed of sound of the measured liquid. With these features the ES-FLOW™ has many similarities with our Coriolis technology based instruments, which are very beneficial compared to Magnetic flow meters or other types of flow meters. With the ES-FLOW™ non-conductive liquids like hydrocarbons, demineralized water and oil-based additives can be measured. Improved ES-FLOW™ Mk II The know-how and experience gained in our specialized domain of developing and manufacturing flow meters have been used to improve the overall performance, hygienic design and accuracy of our ultrasonic flow measurement technology. The new and improved sensor technology meets the highest hygienic standards and is almost twice as accurate at the lower range, as the reading accuracy and the zero stability have been greatly improved. The ES-FLOW™ is available in two versions. The ES-103I is suitable for hygienic purposes, whereas the ES-113I can cover all other areas. The differences lie in certifications and the available process connections. The sensor technology and performance are similar. Designed and authorized for hygienic applications The ES-103I Mk II is designed for applications with the highest hygienic demands. This is achieved by using stainless steel materials and a straight sensor tube design. The acoustic actuators are positioned at the outer surface, meaning no obstacles or other kind of materials are within the flow path of sensor. The instrument is self-draining, easy to clean and contains zero dead volume. The exterior design is rated to IP66 as well as IP67. 3-A authorized EC 1935-2004 Stainless steel wetted parts, no elastomers CIP/SIP compatible Surface quality wetted parts Ra <0.8 µm Fields of application The ES-FLOW™ can be used for a wide variety of applications. Typical applications can be found in Food, Beverage & Pharma for measurement/ control of: natural additives, solvents, carbonated liquids, H2O2 sterilization, demineralized water and liquids with suspended particles. Ultrasonic Wave Technology The operation of Bronkhorst® ES-FLOW™ flow meters is based on the propagation of ultrasound waves inside a very small, straight sensor tube, without obstructions or dead spaces. At the outer surface of the sensor tube multiple transducer discs are located which create ultrasonic sound waves by radial oscillation. Every transducer can send and receive, therefore all up- and down-stream combinations are recorded and processed. By accurately measuring the time difference between the recordings (nanosecond range) the flow velocity and speed of sound is calculated. Knowing these parameters and the exact tube cross-section, the ES-FLOW™ is able to measure liquid volume flows in the range of 4 up to 2-1500 ml/min. The distinctive character of this flow meter is that it’s capable to measure the actual speed of sound, meaning that the technology is liquid independent and calibration per fluid is not necessary.

ES-FLOW™ model ES-103I ES-FLOW™ model ES-113I Hygienic Flow Controller for the Food & Beverage Market The integrated PID controller can be used to drive a control valve or pump, enabling users to establish a complete and compact control loop. In this application example the ES-FLOW™ is controlling a hygienic and 3-A authorized GEMÜ pneumatically operated diaphragm valve at a flowrate of 900 ml/min. This combination makes an excellent hygienic flow controller for a wide range of applications within the Food & Beverage market. This design is also very interesting for the process industry with challenging liquids (e.g. particles) as the risk of clogging is limited due to the hygienic design. Flow Meter Controlled Pumps Pumps are core components in a liquid system. Dosing or metering pumps are able to “measure” the flow of a liquid by positive displacement or rotations. Process conditions, such as temperature, air containment, back pressure and wear and tear, influence the “measured value”, and therefore the pump needs an additional device to make the required correction. The ES-FLOW™ offers the opportunity for direct pump steering. Based on the desired flowrate the ES-FLOW™ controls the speed of the pump to minimise the influence of process conditions and therefore ensures high accuracy and repeatability. Liquid Dosing Set, consisting of an ES-FLOW™ flow meter with integrated PID controller, directly driving a close-coupled pump Versatile multi-purpose instrument Digital, Analog or Fieldbus Communication Readout & control by display Customised I/O outputs: Analog control signals 0…10 Vdc, 0…20 mA controlling pumps or valves Pulse, Frequency or Alarm output Batch Dosing & Counter Functionalities One of the advantages of the ES-FLOW™ is that the instrument is equipped with an integrated counter, totalizer and batch dosing functionality. This dosing technology allows batch dosing of small amounts of liquid additives with only a minimum of tolerance. The firmware is equipped with a “learning function” to correct even the smallest tolerances automatically (e.g. during start-up of the instrument or change of supply batches). The setup is customised to fulfil all requirements of the production; it can easily be integrated in already existing processes and production lines. Moreover, with this batch dosing functionality the instrument can control shut-off valves, proportional valves and pumps. ES-FLOW™ flow meter with close-coupled valve; hygienic and 3-A authorized ES-FLOW™ model ES-103I with Tri-Clamp process connections Application example for candy production During the manufacturing of candy, additives such as colourings, flavourings and acids have to be added to a main stream. The latter is a hot, viscous mass that usually consists of water, sugar and glucose syrup. By using our ultrasonic volume flow meters, the dosing accuracy will be improved, and so is the quality control of the manufacturing process. The below solution consists of 4 ES-FLOW™ ultrasonic flow meters. One is used to measure the main flowrate as the other instruments measure/ control the flow of colouring, flavouring and acid. As these fluids are highly concentrated, only small amounts have to be added. These small amounts can be measured with the ultrasonic flow meter, as the measurement range is within 4 to 2-1500 ml/min with a precision of +/- 0.8% Rd. The overall performance and user friendly operation of the ES-FLOW™ instrument are the main reasons for choosing this device. Moreover, manufacturers of confectionery products using ES-FLOW™ devices, earned back their investments in flow meters by saving costly natural colouring and flavouring agents and large quantities of raw material. Before, when relying on volumetric dosing without flow measurement, errors in the production were detected at a rather late stage, resulting in entire batches of candy that had to be defined as 'second choice'. Using flow meters, poor quality - if any - will be detected in a much earlier stage.
