9.1.3

Input of fluid parameters

Fluid temperature

The fluid temperature is used:

– at the beginning of the measurement for the interpolation of the sound speed and therefore for the calculation of the

recommended transducer distance

– during the measurement for the interpolation of the density and the viscosity of the fluid

This value is only used, if the temperature is not measured. The value has to be within the operating temperature of the
transducers.
• Enter the fluid temperature. In case of a temperature range, enter the average fluid temperature.

• Press ENTER.

9.1.4

Other parameters

Extension cable

In case the transducer cable is extended (e.g., between junction box and transmitter), enter the length of the extension ca-
ble.
• Select the menu item

Extension cable

in the program branch

Parameters

.

• Enter the length of the extension cable.
• Press ENTER.

Measurement settings

• Select the program branch

Options

.

• Press ENTER.

• Select the channel for which a physical quantity has to be

entered (here:

Channel A)

• Press ENTER.
This display will not be indicated if the transmitter has only
one measuring channel.
• Select
