DETACHABLE HORIZONTAL WOLTMANN WATER METER

Classification:


Keyword: Water Meters

 

Detailed


DESCRIPTION

The detachable horizontal woltmann water meter belongs to one of the speed water meters. It uses the water flow to drive the impeller to rotate, and displays the water consumption on the indicating device after transmission by the reduction gear. Compared with the traditional water meter, the detachable horizontal woltmann water meter has the characteristics of small pressure loss and large flow capacity, and is suitable for water measurement in large diameter pipelines.

FEATURE

● Dry type structure: The counting mechanism is vacuum sealed, the dial and numerals aren’t impacted by the water quality,and the readings can be clear permanently.

● Various types: They are divided into rotary vane wheel water meters and spiral type water meters according to the different internal structure.The impeller speed of rotary vane wheel water meters is fast,suits for measuring small diameter pipeline;The impeller speed of spiral type water meters is slow,and suits for measuring the large diameter pipeline.

● High  accuracy:  Some large  diameter mechanical water meters have higher measurement accuracy, such as low starting flow 、wide measurement range 、high measurement accuracy,can measure the total volume of water flowing through pipelines accurately.

● Stable performance: Fewer mechanical parts,low failure rate ,relatively stable performance, can work stably in the various environments for a long time.

● Widely application conditions: Suitable for agricultural irrigation, main pipelines, firefighting pipelines, factories, etc., able to meet the water consumption characteristics and measurement needs of users in different industries.

● High  pressure  resistance:  able  to  withstand  higher  working  pressure  and  meet  the requirements of high-pressure water supply systems.

● Simple structure: Compared to some smart water meters,the mechanical water meters have a simpler structure and are relatively easier to maintain.

● Easy to replace: High degree of standardization of parts ,when a component is damaged,it is convenient to replace.

● Lower price: The price of mechanical water meters is relatively cheaper compared with some high technology smart water meters.
