PIOX S70x 10 Measurement of Concentration and Mass Flow Rate
96 UMPIOX_S7V4-6-3EN, 2018-10-10
10.1.2 Mass Flow Rate Measurement (Optional)
If the transmitter has the option Mass Flow, the mass flow rate is available as an additional physical quantity.
The operating density of the medium in dependence on the concentration and temperature is calculated by means of an
algorithm:
ρ = f(K, T)
The mass flow rate is calculated from the operating density and the volumetric flow rate:
= · ρ

10.2 Activation of Concentration and Mass Flow Rate Measurement
Measurement of the concentration or the mass flow rate (optional) has to be activated:
10.3 Setting the Parameters
• Enter the pipe parameters. Press ENTER.
For the input of the pipe parameters see section 9.1
• Enter the medium parameters. Press ENTER.
For the input of the medium parameters see section 9.2.
• Enter the transducer parameters.
For the input of the transducer parameters see section 9.3.
ρ – operating density
K – concentration
T – temperature
– mass flow rate
– volume flow rate
