Bronkhorst® Warranty Bronkhorst® products are warranted against defects in material and workmanship for a period of three years from the date of shipment, provided they are used in accordance with the ordering specifications and not subject to abuse or physical damage.
Bronkhorst High-Tech B.V. cannot be held liable for any damage resulting from improper use or use for other than the intended purpose. Product description The ES-FLOW™ is a precise and compact volume flow meter with control function for liquids, based on a novel ultrasonic technology. Measuring principle Measuring is done in a straight tube, without obstructions or dead spaces.
The ES-FLOW™ comes with all necessary information for basic operation and maintenance. This section lists all documentation that is relevant to the ES-FLOW™. Some documents are not necessarily part of the scope of delivery, but can be provided on request. Documents with a check mark in the column labeled 'www' can be downloaded from http://www.bronkhorst.com/en/downloads.
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.
· 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 product label. If the product label is missing or if the specified pressure is insufficient, the instrument must not be used and should be returned to the factory.
Fluidic connections The FLOW arrow on the measuring tube indicates the normal flow direction. For normal use, install the ES-FLOW™ in the process line, in accordance with the direction of the FLOW arrow. For bi-directional measuring, install the instrument in the direction where the highest flow will be measured (if applicable).
Bronkhorst® Communication interface Check if the default network settings match the configuration of the fieldbus system (if applicable). If necessary, the default settings can be overruled by changing the appropriate parameters (see Network configuration). Instruction Manual ES-FLOW™ 9.17.116B...
For controllers, give setpoint = 100% or use special Control mode = 8 (valve fully open), to ensure getting the highest possible flow rate. Control mode 8 bypasses the PID controller, which is particularly useful when having the ES-FLOW™ set to a low capacity flow range. User interface The screen representations in this section are for illustration purposes only.

The Controller sub menu is only available if the control function of the instrument is enabled. This setting is part of the instrument configuration at the factory. Because controlling characteristics are optimized during manufacture, Bronkhorst strongly advises not to change these parameters. If changing controller settings is absolutely necessary, it should be performed by or under supervision of trained service personnel only.
3.3.3.3 Counter Bronkhorst® flow meters have a built-in counter function, which can be used to monitor and/or control the amount of media flowing through the instrument. The flow can be stopped or changed when a certain limit is reached. Until the counter is reset, the counter setpoint overrules the regular setpoint.

FLOW-BUS In a FLOW-BUS system, instrument configuration and operation can be done using the free Bronkhorst® FlowWare tools. These tools provide a graphical interface to the ProPar protocol (used by FLOW-BUS), for monitoring and changing instrument settings. Digital communication between the instrument and the client software (e.g. FlowPlot, FlowTune™) is handled by FlowDDE, a Dynamic Data Exchange server (DDE), the core component of the FlowWare software.

Maintenance General No regular maintenance is required if the ES-FLOW is operated properly, with clean media, compatible with the wetted materials, avoiding pressure and thermal shocks and vibrations. Units may be purged with a clean, dry and inert gas. In case of severe contamination, cleaning the inside of the device may be required. After cleaning, the instrument has to be re-calibrated.
