As part of Bronkhorst’s volumetric liquid flow meters/controllers, the ES-FLOW ES-103I/ES-113I are designed for very low flow ranges. They operate on an innovative measuring principle, using ultrasound in a very small and straight tube. A broad range of liquids can be measured independently of fluid density, temperature and viscosity. The flow ranges are from 4 to 1500 ml/min. Due to the combination of a straight sensor tube with zero dead volume, self-drainability, orbital TIG-welding and hygienic connections, this flow meter can be used for hygienic applications.
For non-hygienic applications, the instruments can also be equipped with compression type fittings
Wetted parts are made of stainless steel, except for the rubber gaskets at the Triclamp or flange connections. The exterior design is compliant to IP67. They feature a user interface as a capacitive touchscreen with a TFT display to operate and readout the instrument. The flow meters can be connected to a dosing pump or a control valve to form a closed control loop. The electronic control function forms part of the normal circuitry in the meter.
