Actaris rotary meters are used when very accurate measurement is required in circumstances where the gas flow can be low or irregular. Because of its volumetric principle, the Delta meter's metrology is not influenced by installation conditions. Consequently, it can be used to build very compact stations without installing a straight pipe inlet in front of the meter. Delta meters are approved for fiscal use.
