Bronkhorst presents their new generation of ES-FLOW™ Ultrasonic Flow Meters for low flow rates of water, additives and other liquid substances.
The improved flow meters measure volume flow from 2 up to 1500 ml/min with even higher precision, high linearity and low pressure drop, using ultrasound in a small-bore tube. The instruments are liquid-independent, thanks to the unique measuring principle in which the actual sound velocity is accounted for in the flow calculations. Thanks to the combination of a straight sensor tube with zero dead volume the flow meter is self-draining.
The flow meter with orbital TIG-welded flanges is CIP cleanable, and now meets 3-A sanitary standards for hygienic applications. Wetted parts are made of stainless steel, the exterior design is rated to IP66 or IP67. The local user interface is a capacitive touchscreen with a TFT display to operate and readout the instrument. For remote operation, Bronkhorst added a variety of Ethernet based fieldbuses to the already available range of analogue and digital communication options. The on-board PID controller can be used to drive a control valve or pump, enabling users to establish a complete, compact control loop. Hygienic Flow Control configuration. Typical applications for the new low-flow liquid flow meters and controllers can be found in Food, Beverage & Pharma (e.g. additives, sterilization of packages), Medical and Chemical (e.g. catalysts, reagents) and many other markets which require precision fluid handling e.g. fuel consumption measurement and dosing of hydrocarbons, demineralised water, colorants or lubricants in many industries.
