WI-50~300E/A (cold water)
 

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:
--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;
--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;
--It can measure dirty water. The universality of the measuring mechanism is great.
--Negotiability ability is wide. Accuracy in measurement is exact.

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%.
