Bronkhorst presents its new generation of ES-Flow ultrasonic flowmeters for low flow rates of water, additives and other liquid substances. The improved flowmeters measure volume flow from 2 to 1500 ml / min with even greater accuracy, high linearity and low pressure drop, using ultrasound in a small diameter tube.
The instruments are liquid independent, thanks to a unique measurement principle that takes the actual speed of sound into account in flow calculations. Thanks to the combination of a straight tube with zero dead volume, the flowmeter is self-draining. The flowmeter consisting of orbital welds with sanitary flanges is CIP or SIP cleanable and now meets 3-A sanitary standards for hygienic applications.
The wetted parts are made of stainless steel, and the exterior design is IP67 rated. The user interface is a capacitive touch screen with TFT display for reading measurements and operating the instrument.
For remote operation, Bronkhorst has added various Ethernet-based fieldbuses to the list of analog and digital communication options already available. The integrated PID control card can be used to drive a control valve or pump, allowing users to establish a compact and complete control loop.
The new regulators and flowmeters for low liquid flow rates are used in processes in the food, pharmaceutical (e.g. additives, sterilization of packaging), medical, chemical (e.g.: catalysts, reagents) and other sectors. in other markets that require handling fluids, for example, for measuring fuel consumption and dosing hydrocarbons, demineralized water, dyes or lubricants in different industries.
