Low-Flow Ultrasonic Flow Meters for Liquids
ES-FLOW™ model ES-113I Liquid Flow Meters (LFMs) are suited for precise measurement of volume flow ranges between 2 and 1500 ml/min. The LFM consists of a innovative ultrasonic flow sensor and an IP66/IP67 protected measuring head with bright LCD display and capacitive touchscreen for adjustment of the settings e.g. for flow indication, alarm, totalisation and control (if applicable). The electronics include a PID controller for optional flow control by means of a separately mounted control valve or pump. ES-FLOW™ model ES-113I has orbitally welded compression type connections, making this instrument suitable for operating pressures up to 100 bar.
Bronkhorst® ES-FLOW™ series are equipped with advanced electronics, 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.
The second generation of the ES-FLOW series, is indicated by suffix MkII.
ES-FLOW model ES-103I liquid flow meters with Tri-Clamps can be delivered with 3-A certificate. Bronkhorst can also supply the Manufacturer Declaration for EC Regulation Nos. 1935/2004 and 2023/2006 (Food Contact Materials). ES-103I can be combined with a GEMÜ 650 pneumatic diaphragm valve to make it an excellent hygienic flow controller for a wide range of applications within the Food & Beverage market. The GEMÜ valve is also 3-A authorised.
