9.17.120A

Consult the applicable fieldbus manual for information about setting up and terminating a FLOW-BUS, Modbus or

PROFIBUS DP network.

3.7.5

Service port

The micro USB port provides an alternative way to operate the instrument via RS232. With a micro USB to USB2.0 adapter

cable, the instrument can be connected to a Windows computer. This enables RS232 operation with the use of the free

Bronkhorst® FlowWare software, even if the instrument is already being operated through one of the other interfaces

(analog, RS232 or fieldbus, if applicable).

3.8

Adjusting zero point

Due to the mechanical characteristics of its sensor tube, a (very small) offset signal is inherent to a mass flow

meter/controller. As a result of this zero-stability error, a flow may be detected when actually there is none.

The zero-stability error can be neutralized by adjusting the zero point of the instrument (the signal that corresponds to zero

flow). Immediately after zeroing, the zero-stability error is 0%. In ideal situations, i.e. when process conditions are constant,

the error will remain unchanged.

A certain tolerance around the zero point is allowable. Significant changes in ambient or process conditions, however, can

affect the zero-stability error to the extent that the instrument needs to be adapted to the new conditions, by re-adjusting

the zero point.

The zero point of a Bronkhorst® flow meter/controller is factory adjusted at approximately 20 °C and atmospheric pressure,

with the instrument positioned upright. If the ambient conditions or mounting orientation are significantly different,

zeroing a new instrument is recommended before using it for the first time.

The following factors affect the zero-stability error (in order of importance):

fluid temperature

ambient temperature

mounting orientation

(inlet) pressure

fluid density

fluid viscosity

vibrations from the environment

pressure fluctuations

Zeroing an instrument requires that:

the ambient conditions (temperature, pressure) match those of the operating environment of the instrument

the instrument is filled homogeneously with the operational media

there is absolutely no flow through the instrument; preferably, this is achieved by closing a valve immediately after the

outlet of the instrument (control valve, shut-off valve)

Blocking the flow through the instrument is absolutely essential; zeroing an instrument while there is still a flow will lead to

measurement errors.

Adjusting the zero point of an instrument can be done by the following methods:

manually (using the multifunctional switch)

digitally (via RS232 or fieldbus)

with the autozero function of a Bronkhorst® readout and control unit

Once started, the procedure takes approximately 40 seconds to complete (longer if the output signal is unstable), regardless

of the preferred method.
