ES-FLOW™ are Volumetric Liquid Flow Meters for very low flow ranges. 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.
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. Wetted parts are made of stainless steel, except for the rubber gaskets at the Triclamp or flange connections. The exterior design is according to IP66 as well as IP67. For non-hygienic applications, the instruments can also be equipped with compression type fittings.
The user interface is a capacitive touchscreen with a TFT display to operate and readout the instrument.
The liquid flow meter 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.
