This type of water meter also can be used for a remote reading transmission system as equipped with a built-in sensor.
APPLICATION: To totalize the total volume of cold (hot) water passing through the pipeline.
WORKING CONDITION:
The max.admissible water pressure: 1.0MPa.
Water temperature: 0.1℃~50℃.
FEATURES:
--The water meters of this series were especially designed to give a reliable measurement of waters carrying also solid particles。
--Head lose of the meters are negligible, enabling efficient operation to be maintained where only a limited head of water is available。
--The body and cap flange are coated by an epoxy varnish treatment to insure better anticorrosive effect during long service time; Capsulated counter can give clear reading even when the water is not very clean; Reed contact for remote reading can supplied upon request。
--The self-cleaning propeller of three blade design avoids clogging by grass or other solid particles held in the water。
--The measuring mechanism is robust in construction with few moving parts subject to wear, and can be easily removed for inspection and maintenance。 --The meters are very suitable for irrigated water and can be employed also for intermittent or seasonal services.
Maximum permissible error:
From Transitional flow up to Maximum flow both  inclusive: ± 2%;
From Minimum flow inclusive up to Transitional flow :± 5%。
