Variable area flowmeters

RA 77

• Direct reading on a calibrated tube
• Body: PVC / Reading tube: Glass
• For agressive fluids
• Fittings: Unions or flanges
• Adjustable limit value switches

APPLICATIONS

- Water treatment, Industrial process (paper mill, textiles etc.), chemical and pharmaceutical industries, heating and cooling plants.

DESCRIPTION

Their design, plastic body and glass tube, makes them particularly suitable for aggressive fluids and corrosive environment.
The measuring principle is that of the variable area flowmeter, the float is moved by the fluid inside a calibrated conical glass tube. The borosilicate glass conical tube is inside a plastic protection case with a transparent reading window.
