Combined with a wide load range, this type of meter is used either for highly precise measurement of highly variable flow rates or as an alternative to the classic combination meters, with main and secondary meter.
In contrast to Woltman meters, the ETK-N/ETK-M does not require an inlet zone, since, as a single-jet meter, it is insensitive to swirling flows. Approved for horizontal installation position, this meter type is very flexible to use and can be an alternative in almost all areas of application of the classic combination meter.
