Page 8: Documentation
Bronkhorst® Application The combination of a straight sensor tube with zero dead volume, self-drainability and hygienic connections, makes the ES- FLOW especially suitable for hygienic applications. Examples of typical use are the measuring of food ingredients like flavourings or syrups, or measuring concentrates in CIP units. For non-hygienic applications, the instrument can be equipped with compression type fittings. -

Page 10: Customized I/O Options
Bronkhorst® 1.5.1 Customized I/O options ES-FLOW™ instruments offer various customized input/output functions through pin 5 of the M12 connector and through pin 2 of the M8 connector as an option. I/O options are factory installed as specified at ordering time, and cannot be changed manually. - Page 11 (controller enabled, see model key). · If the controller is enabled, the M8 connector can always be used to control a Bronkhorst® valve (through pin 3). · Although it is theoretically possible to have 3 controller options installed, no more than 1 signal should be used at any time.

Page 12: Installation
· Ambient temperature · Input and output signal Bronkhorst® instruments are pressure tested to 1.5 times the requested pressure rating and outboard leak tested to at least 2 * 10 mbar l/s Helium. The tested pressure is specified on the serial number label. If the serial number label is missing or if the specified pressure is insufficient, the instrument must not be used and should be returned to the factory. -
Page 13: Orientation
Its orientation can only be altered by repositioning the entire instrument. On models starting from MkII, the flow direction and display orientation can be adjusted at the factory, for which the instrument has to be returned.

Page 14: Electrical Connections
The device carries the CE-mark and is compliant with the concerning EMC requirements. However, EMC requirements can only be met using appropriate cables and connector/gland assemblies. Bronkhorst recommends the use of their standard cables. These cables have the right connectors and loose ends (if any) are marked to help prevent wrong connection. -
Page 15: Operation

Each communication protocol uses its own methods for communicating with instruments and accessing parameters. FLOW-BUS Digital Bronkhorst® instruments can be monitored and operated via RS-232 using the free FlowWare software tools for Windows. These tools provide a graphical interface to the ProPar protocol (used by FLOW-BUS), for monitoring and changing instrument parameters. -

Page 42: Controller
Controller The picture below shows a basic diagram of the PID controller algorithm (proportional, integral, derivative) used by digital Bronkhorst® instruments. The controller speed controls the overall performance of the controller algorithm. Basically, to adjust the controller response, only the controller speed needs to be changed. - Page 43 Bronkhorst® The control characteristics are optimized during production. These parameters should only be changed if absolutely necessary, and only by or under the supervision of trained service personnel. Controller Speed Type Access Range FlowDDE FLOW-BUS Modbus Float 0.2…5 114/30 0xF2F0…0xF2F1/62193…62194 This parameter sets the overall controller speed factor for the selected fluid set.

Page 44: Master/Slave Configuration (Flow-Bus)
Bronkhorst® 3.4.7 Master/slave configuration (FLOW-BUS) Normally, there is no communication between slave instruments in a fieldbus system. The FLOW-BUS protocol, however, provides a feature to set up a master/slave relationship between two instruments. The typical behavior of a slave instrument is to automatically set its own setpoint relative to the output (measurement value) of its master. -

Page 47: Default Control Mode
Adjusting zero point The zero point (the signal that corresponds to zero flow) of a Bronkhorst® flow meter/controller is factory adjusted at approximately 20 °C and atmospheric pressure, with the instrument in an upright position. If the ambient conditions or mounting position are significantly different, the instrument might detect a flow when actually there is none. -

Bronkhorst® 3.5.1 Autozero function The readout and control unit provides an automatic function for re-adjusting the zero-point of a flow meter, which automatically steps through the required parameter settings. This autozero function can be found in the Advanced section of the Settings menu: 1. -
Page 49: Maintenance
Inexpertly servicing instruments can lead to serious personal injury and/or damage to the instrument or the system it is used in. Servicing must therefore be performed by trained and qualified personnel. Contact your Bronkhorst representative for information about cleaning and calibration. Bronkhorst has a trained staff available. -
Page 50: Troubleshooting And Service
Energizing and de-energizing the equipment can indicate whether there is an electronic failure. After energizing, control behavior can be checked by applying fluid pressure. If you suspect leakage, do not disassemble the device for inspection, but contact your Bronkhorst representative for service or repairs. - Page 51 Check the system for leakage.
