ES-FLOW models
Our ES-FLOW volume flow meters offer liquid independent measurement of low volume flow rates. The instruments operate on a innovative measuring principle, using ultrasound in a very small, straight tube. A wide range of liquids can be measured independent of fluid density, temperature and viscosity.
