Most of our flowmeters have a library of standard flowmeter programmed into them. If the liquid to be measured is not in the list there are two things that can be done:

  1. Choose Water from the menu. This might seem unhelpful, but water has a good average set of values for the three main parameters that the flowmeter needs. Using water for a non-water based application may not be perfect, but can provide a setup that will allow the device to measure. N.B. river water, waste water, sewage water etc. are all Water; It is only the solid content that varies.
  2. If more accurate data is desired for the media parameters, select User from the drop-down list. The flowmeter will then ask for three sets of data:
    – Kinematic viscosity in mm²/s
    – Density in kg/m³
    – Medium C speed in m/s

The C-velocity of the medium is often an unknown data. In fact, it is the conduction speed of a liquid to ultrasound. There is an overview of non-standard media in the back of the manual for this purpose. If the data is not found there, please contact us for technical support and advice.

Please note that any manually entered liquid information is only applicable at that temperature.
