Turbines gas meters are flow meters . The
flow of gas turns a turbine wheel and the
rotating speed of the turbine is propor-
tional to the linear speed of the gas . The
movement is mechanically transmitted to
the totaliser through the magnetic cou-
pling . Detailed characteristics are given in
Annex 1
