Standard Measurement

The units for the cyclical and acyclical data can be set here. All parameters accessible to the PLC will be transmitted or received by the specified unit.

The refresh time is the minimum time needed to update a measurement value. The refresh time has no effect on the damping of the measured values. The refresh time of the temperature values is a constant but the refresh time of the other measurement values can be adapted to the process:

A very short refresh time is needed if the process requires quick volume flow rate measurement updates, for example for very short dosing.
A long refresh time is sufficient if for example there are slow flow rate changes in the process.

3 refresh time modes are available:

To get as accurate measurements of the volume flow rate, the mass flow rate or the liquid velocity as possible, you can activate the compensation of the kinematic viscosity (in mm

2

/s). The following kinematic viscosity compensations are available:

For water or a liquid whose viscosity u (in mm

2

/s) varies with the temperature T (in °C) like the viscosity of water and in the same range as water. Default setting. The related equation is:

The viscosity compensation value can be selected from Water, Constant, Linear, Quadratic, Inverse Quadratic
