The new, compact ES-FLOW™ Ultrasonic Flow Meter/Controller Series ES-113C was designed for the OEM market to measure or dose low volume flows with high precision, high linearity and low pressure drop. Liquid flows from 2 up to 1500 ml/min can be measured using ultrasound in a small bore tube. This technology is independent of fluid density, temperature and viscosity. The instrument therefore does not require recalibration when switching fluids.

Thanks to the combination of a straight sensor tube with zero dead volume and transducers positioned at the outer surface, the flow meter is self-draining and easy to clean. Wetted parts are made of stainless steel, the exterior design is rated to IP66/IP67. The on-board PID controller can be used to drive a control valve or pump. This enables users to establish a complete, compact control loop. Moreover, the instrument features various fieldbus options, customizable I/O functions and temperature as secondary output.

Typical applications for the new low-flow liquid flow meters and controllers can be found in Food, Beverage & Pharma (e.g. additives, sterilization), Medical and Chemical (e.g. for dialysis, catalysts, reagents) and many other markets which require precision fluid handling e.g. fuel consumption measurement and dosing of colorants or lubricants in many industries.
