NT UF 811 CO GB (c) / March 2014 

6.1 Principle 

Each Uf 811 includes a miniature PLC. This PLC allows Ultraflux to easily install additional features for this 
flow meter. 

On request, Ultraflux can quickly integrate a new feature for your Uf 811. 

 

6.2 Application example 

 

6.2.1

 

Water temperature calculation 

The water temperature can be determined from its celerity (via a calculation). 

You will find in the appendix the polynomial used to determine the temperature of the water based on the 

celerity measured by our flow meters. 
The function engine allows us to carry out this calculation internally in the flow meter.
