Flow indicator HVF-E

Visual flow indicators with flow-meter sensor, technopolymer ends Features and applications: The indicator can be mounted in any position. In case of mounting on rigid tubes, it is recommended to place the indicator perfectly aligned with the tubes. The indicator operates with two-way liquid flows with a viscosity lower than 30cSt. In order to allow the propeller rotation, a minimum flow rate is required depending on the type of fluid and its viscosity. At the passage of the minimum flow rate, the rotor starts to rotate with a speed proportional to the fluid flow. The inductive sensor, completely separated from the liquid passage area, reads the passage of the two metal clips mounted on the rotor, providing a frequency variation that can be transformed into a reading of the flow rate by connection to a PLC. Ends and sensor holder: Polypropylene based (PP) technopolymer, black colour, matte finish. Axis and rotor propeller: Polypropylene based (PP) technopolymer, red colour. AISI 304 stainless steel sensor activating clips. Tubular window: Borosilicate glass, high-resistance, also suitable for use with glycol-based solutions. Sensor: Nickel-plated brass inductive sensor Tie rods: AISI 316L stainless steel. Packing rings: NBR synthetic rubber. Standard execution: Brass bosses with cylindrical gas thread according to UNI ISO 228/1. Maximum continuous working temperature: 100° C.
