Low-Flow Ultrasonic Flow Meters for Liquids

The innovative ES-FLOW ES-112C Ultrasonic Liquid Flow Meter/Controller is designed for measuring volume flow ranges between 0,4 and 200 ml/min with high precision, high linearity and low pressure drop using Ultrasonic Wave Technology in a small bore tube. Liquids can be measured independent of fluid density, temperature and viscosity, therefore recalibration per fluid is unnecessary. The flow meter has a straight sensor tube design with the actuators positioned at the outer surface. Therefore, the instrument is easy to clean. All wetted parts are made of stainless steel and PEEK, build in an aluminium housing. The on-board PID controller can be used to drive a control valve or pump, enabling users to establish a complete, compact control loop.

Bronkhorst® ES-FLOW series are equipped with a digital pc-board, offering high accuracy, excellent temperature stability and fast response. The main digital pc-board contains all of the general functions needed for measurement and control. In addition to the standard RS232 output the instruments also offer analog I/O. As an option, an on-board interface can be mounted to provide CANopen®, DeviceNet™, EtherCAT®, PROFIBUS DP, PROFINET, Modbus RTU, ASCII or TCP/IP, EtherNet/IP, POWERLINK or FLOW-BUS protocols.
