Low-Flow Ultrasonic Flow Meters for Liquids

ES-FLOW™ model ES-103I Liquid Flow Meters (LFMs) are suited for precise measurement of volume flow ranges between 2 and 1500 ml/min at operating pressures up to 10 bar. 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-103I has orbitally welded TriClamp flanges for hygienic applications.

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 PROFIBUS DP, PROFINET, CANopen®, DeviceNet™, Modbus RTU/ASCII or FLOW-BUS protocols.

November 2020, launch of ES-FLOW MkII generation

With the introduction of the second generation of our ES-FLOW series, indicated by suffix MkII, Bronkhorst realised some important improvements and new options. Here are the main MkII-highlights:

  • Hygienic Standards 3-A
    The ES-103I MkII with Tri-Clamp flanges is authorized by 3-A, meeting the highest hygienic standards.
  • Hygienic Flow Controller
    Combining the ES-FLOW flow meter with a GEMÜ 650 pneumatic diaphragm valve makes an excellent hygienic flow controller for a wide range of applications within the Food & Beverage market. The GEMÜ valve is also 3-A authorized.
  • EC Regulation Nos. 1935/2004 and 2023/2006 (Food Contact Materials)
    By meeting the requirements, Bronkhorst can provide a Manufacturer Declaration for these regulations.
  • Improved accuracy and rangeability
  • Additional functionalities and EtherNet fieldbus options
