Twin Turbine Gas Meter ETTM-by Measurement Systems and Group.

MUMBAI, India - April 22, 2013 - PRLog -- The performance of the two turbine wheels is continuously compared to each other by the diagnostics. This is similar to the serial comparison of two separate meters, a process commonly applied in European border stations.

ETTM Twin Turbine Gas Meter ETTM with a MFMLPLC Flow computer as remote index, gives full real time diagnostics and alarming as well as absolute accuracy by auto corrections such as curve linearization.

ETTM Twin Turbine Gas Meter ETTM with an electronic Index also gives significant diagnostics and alarming functions. Due to the unpowered counting system (PCS), battery life time of the index is 15 years with just one AA cell. Replacing the battery will not cause any loss of data.
