These meters are used for measuring the instant flow rate of liquid and gases. These meters are use where the metal wetted parts cannot be acceptable, such as with deionized water or corrosive fluids.
The cost of these rotameters is low and having high impact strength. Due to plastic and fittings care must be taken during installation.
