Page 13: Model Key
Bronkhorst® Model key The model key on the serial number label contains information about the technical properties of the product as ordered. The actual properties of your instrument can be retrieved from the diagram below. 3.3.1 Customized I/O options ES-FLOW™ 1xxC instruments offer various customized input/output functions through pin 5 of the... - Page 14 Bronkhorst® Code Description B1V* 4…20 mA sourcing output, controller Analog signal for pump or external valve steering (control signal only). When the controller output is used for pump or external valve steering (mass flow meters only), make sure to set parameter Valve maximum to 0.3 [A]. For mass flow controllers, the controller output is limited to a value below 20 mA, due to the maximum valve current restriction.
- Page 15 (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 16: Installation
Bronkhorst® Installation Mounting For stable fixation to a rigid and stable surface or construction, use the threaded mounting holes in the rear of the instrument housing (see product overview). Consult the dimensional drawing for the exact size and locations. 4.1.1 Location Gas bubbles in the liquid can lead to measuring errors. -
Page 17: Electrical Connections
Route cables as closely as possible alongside metal structures or components. · Ensure all electrical components are grounded to earth. When in doubt about the shielding of your cabling and/or electrical connections, contact your Bronkhorst representative. Always turn off electrical power before connecting or disconnecting equipment electrically. Fieldbus connection Never power the instrument simultaneously from two different power sources (e.g. -

Page 19: Default Valve State
Bronkhorst® 5.4.2 Default valve state When a controlling instrument is not powered or cannot communicate with the fieldbus network (if applicable), all electrical valves operated by the instrument (whether integrated or external) automatically return to their default state. The default state is closed for 'normally closed' valves (n/c) and fully open for 'normally open' valves (n/o). -

Page 22: Disabling Multifunctional Switch
Adjusting zero point Zero-stability The zero point of a Bronkhorst® flow meter/controller (the measurement signal that indicates the absence of a flow) is factory adjusted with water at approximately 20 °C and atmospheric pressure (ambient conditions), with the instrument positioned upright. Under normal circumstances, the zero point will remain stable. However, in rare cases (for example due to strong fluctuations in temperature and/or pressure), the instrument might develop a slight deviation of the measured value from the zero point, causing it to detect a flow when in reality there is none. -
Page 23: Manual Procedure
Bronkhorst® Prerequisites Zeroing an instrument requires that: · the ambient conditions (temperature, pressure) match those of the operating environment of the instrument. · the instrument is filled homogeneously and pressurized with the operational media, according to the typical process conditions. -

Bronkhorst® Digital communication RS-232 communication 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, for monitoring and editing parameter values. The FlowWare toolkit provides functionality for monitoring and operating digital instruments (FlowSuite, FlowPlot), selection of the active fluid and configuration of the fieldbus connection (if applicable). -

Modbus address blocks are two bytes big. Larger data types use up to 8 subsequent address blocks, resulting in a maximum variable length of 16 bytes. Values longer than the maximum length are truncated. For more detailed information about setting up a Modbus network with Bronkhorst® instruments, consult the Modbus manual (see Documentation). -

Page 33: Controller
Controller The picture below is a simplified visualization 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 34 Bronkhorst® The algorithm is based upon the difference between the setpoint and the measured value (called the error value). The correction signal to eliminate the error is assembled from 3 components (giving the algorithm its name): · The P-action (proportional) multiplies the error value by a constant factor, to adjust the measure towards the (new) setpoint.
