Woltman water meter with removable measurement mechanism, pulse emitter for remote reading
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 OR 1.6MPa.
Water temperature:
0.1℃~50℃ for cold water;
0.1℃~90℃ for hot water.
FEATURES:
--Measuring mechanism has three different types.
--Removable element structure, it is easy for installation and maintenance, register for universal use within this range detachable without Removing the meter from the pipeline;
--Dry-dial, Magnetic drive sensitive action, small pressure loss;
--Counter of roller-big central pointer type, easy reading;
--Vacuum sealed register ensures the dial keeps free from fog and keeps the reading clear in a long term service;
-Selected high quality materials for steady & reliable characteristic;
MAXIMUM PERMISSIBLE ERROR:
From transitional flow up to maximum flow both inclusive:
±2% for cold water.
±3% for hot water.
From minimum flow inclusive up to transitional flow: ±5%.
