Measurement Method - Pce Instruments Pce-Tds 200 Serie Bedienungsanleitung

5.1.2 Medium
The Medium menu allows you to select one of the standard media or to enter the sound velocity
and kinematic viscosity of a user-defined medium. The following standard media are available:
•
Water
•
Sea water
•
Oil
•
Crude oil
•
Methanol
•
Ethanol
•
Diesel
•
Gasoline
•
Petroleum
A user-defined medium is selected by entering the sound velocity and the kinematic viscosity of
the medium. To do this, select the menu item Custom. A dialogue for entering the sound velocity
opens. Here, each decimal place can be selected with the RIGHT/LEFT arrow keys and edited
with the UP/DOWN arrow keys.
Then confirm with the OK key. The dialogue changes so that you can enter the dynamic viscosity.
Enter the dynamic viscosity of your medium and confirm again with the OK key. The dialogue is
closed and the parameters are adopted.
5.1.3 Sensors
The flow sensors used are selected in the Sensors menu. The TDS-S1 sensors (outer diameter
20 ... 100 mm) and the TDS-M1 sensors (outer diameter 50 ... 700 mm) are available for selection.
5.1.4

Measurement method

In the Measurement method menu, the method for mounting the sensors is selected. The Z, V, N
and W methods are available for selection. A more detailed explanation of the measurement
methods can be found in chapter Fehler! Verweisquelle konnte nicht gefunden werden..
5.1.5 Temperature
The Temperature menu is used to enter the manual compensation temperature. This is used for
compensation of the sound velocity and the kinematic viscosity for the medium water (all other
media are not temperature compensated).
In addition, the thermocouple types and any offsets required for the two temperature measure-
ment channels are set in this menu (PCE-TDS 200+ only).
