EV Series flow meter is a variable area flowmeter, the main material is polycarbonate (PC) or polysulfone (PSU), high-temperature corrosion-resistant properties. As the float is in compression under the action of the spring movement, the flow can be placed at any angle. Red traffic card standard ease of use and identification of the maximum working pressure to 1.0 MPa.
Working pressure: ≤ 1.0MPa
Operating Temperature: Polycarbonate: 0-80 ° C, poly-sulfone: 0-120 ° C
Accuracy: ± 6%

English name is flowmeter of the flow meter, the national science and technology noun authorized committee to define it as: indicating measured flow and in the selected time interval fluid volume meter.Is simply used to measure the fluid Flow in a pipe or channel instrument, commonly used in engineering units m3 / h, it can be divided into the instantaneous Flow and Total Flow Rate , the instantaneous Flow Rate per unit of time closed pipes or the amount of open channel cross-section, Flow through the material can be gas, liquid and solid;Cumulative flow is in a certain period of time interval (day, week, month, year) fluid flows through the closed pipes or open channel section of the cumulative amount effectively.Cumulative flow can also be obtained through the integration of the transient flow of time, so the instantaneous flow and cumulative flow meter can be mutual conversion between.
