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 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,...

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...

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...
