Electronic flow meter for water supply

Tangential fan wheel type flow meter

Outline and features

This is a flow meter realized by loading an electronic indicating & counting unit on the measuring section of an impeller type flow meter for water. It is provided with the ""user setting function"" that allows the user to change measuring conditions in the field, for adaptation to a wide variety of applications.
* Simple structure having no other mechanism but the measuring section
* On-site mode settings by operating the buttons on the counting unit
* Simulated output function, facilitating maintenance in the field

Applications

* Measurement control of water feed to boilers, cold water, warm water and hot water for industrial use in various kinds of plants, such as chemical and water treatment plants
