Operation
The
ES-FLOW™
can be operated with the integrated readout and control unit, as well as
digitally, via RS232 or fieldbus (Modbus, FLOW-BUS, PROFIBUS DP or DeviceNet™), or in
analog mode. The readout and control unit has a capacitive touchscreen with a TFT
display. The fluid temperature can be read out as a secondary output. An on-board PID
controller can be used to drive a control valve or pump, establishing a complete, compact
control loop.
Multi-range
The
ES-FLOW™
offers multi-range functionality: factory calibrated ranges can be re-
ranged to a different full scale range. Because of the extremely high linearity of the sensor, this does not affect the original
accuracy specifications.
The instrument comes with a calibration certificate for all supported full scale ranges. The actual full scale of the instrument
is set to a value as ordered.

A full list of instrument parameters can be found in the Instruction manual RS232 interface (document no 9.17.027).
However, most Bronkhorst® instruments only support a limited set of parameters.
Be aware that some unsupported parameters may be ignored by the device or may even have harmful (side) effects if used.
