The flowmeter of the series RIV300, is a flowmeter deflector with return spring and the flow reading to index. Suitable for water and gas flows is designed for applications with horizontal or vertical depending on the specific customer. They are not required straight portions downstream and upstream of the instrument and the load losses are almost nonexistent.And it is foreseen the possibility of applying inductive alarms for minimum and maximum range. The reduced overall dimensions, the low weight and the reading magnetic coupling flowmeter make this practical and simple to install and above all eliminate any maintenance on the measuring body.

Principle of operation:
The thrust of the fluid exerts a torque on the deflector of the instrument that overcomes the contrast of a torsion spring and causes a rotation of the deflector that is proportional to the value of the flow rate through the instrument. The angle of rotation of the deflector is moved to an index by means of a magnetic coupling which avoids the introduction of friction or fluid leaks.

Fields of application:
The flow deflector turns out to be a compact instrument, much reduced in gauge and highly suitable for the measurement of fluids that also contain solids in suspension.
It can be applied in many industries such as:
• chemical
• water treatment
• pharmaceutical
• paper
• pools
• fire protection systems
