6.4 Operating mode

The parameters for the different operating modes are described in the following table.

Operating mode /

(order code)

Description Additional parameters required Parameter setting

Liquid Volume / NL1 Actual volume flow of the liquid

medium

— —

Liquid Volume

(temperature

compensated) / NL2

Standard volume flow in the

normal condition

Measuring medium temperature

With internal temperature sensor.

No information required, the measured value

from the temperature sensor is used.

Default setting for the temperature value:

Device Setup / Plant/Customized /

Compensation Setting -> Preset Int.Temp

Reference temperature in the normal

condition

Device Setup / Plant/Customized /

Compensation Setting -> Ref. Temperature

Volume expansion coefficient Device Setup / Plant/Customized /

Compensation Setting -> Volume Exp.Coef.

Liquid Mass (no

adjustment) / NL3

Liquid mass flow, based on direct

determination of the operating

density via analog input, HART

input or default setting.

Operating density

2) 3)

Via analog input:

Input/Output / Field Input / Analog In Value ->

Density

Via HART input:

Input/Output / Field Input / Hart In Value ->

Density

Default setting for the density:

Device Setup / Plant/Customized /

Compensation Setting -> Preset Density

Liquid Mass (density

adjustment) / NL3

Fluid mass flow, based on

reference density and density

expansion coefficient in the

normal condition

Measuring medium temperature

With internal temperature sensor.

No information required, the measured value

from the temperature sensor is used.

Default setting for the temperature value:

Device Setup / Plant/Customized /

Compensation Setting -> Preset Int.Temp

Reference temperature in the normal

condition

Device Setup / Plant/Customized /

Compensation Setting -> Ref. Temperature

Density expansion coefficient Device Setup / Plant/Customized /

Compensation Setting -> Density Exp.Coef.

Reference density in the normal condition Device Setup / Plant/Customized /

Compensation Setting -> Ref. Density

1) The highest priority of the device is to record the operating temperature.

2) The highest priority of the device is to record the density via the analog input, as long as the analog input is activated as a density input. If the analog input is not

available as a density input, the system attempts to record the density via the HART input. If both the analog input and the HART input are deactivated as a density

input, the system uses the default density value.

3) The connection via the analog input or HART input is described in the chapter titled „Electrical connections“ on page 21.
