Specification

Spring-tube flowmeters EV are used for flow measuring of liquids (water, gases), where it is essential to measure instantaneous flow.

Flowmeters work on a principle of floats orifice plate resistance to spring in a closed cylindric measuring tube.

Flowmeters are equipped with two adjustable red needles of limiting values and a scale liter per minute, alternatively a scale for gas measuring. They are suitable for all positions of installation. Only products PC, PSU are supplied with a high temperature and corrosive resistance.
