Sight flow indicators RIZUR-VIP-2 and RIZUR-VIP-3

Sight flow indicators RIZUR-VIP are manufactured according to TU and are used for the visual monitoring and flow control in the pipelines.

Download description
Sight flow indicators RIZUR-VIP are designed for the sight flow control, as well as quantity and quality control of the medium (liquid, gas, transparent, semi-transparent, coloured) in the pipelines. The indicator can also help to determine the presence or absence of the media, control its colour and transparency. The equipment can be mounted vertically and horizontally.The direction of the flow is indicated by an arrow on the housing. 

Sight flow indicators are manufactured with nominal width of 15…500mm and can be used in the systems with pressure 1,6 MPа, 2,5 MPа, 4,0 MPа (depending on the design variant), as well as up to 6,3MPa, 10,0MPa, 16,0MPa (are possible upon a request) and in the temperature conditions of − 60 °С … + 280 °С/+ 500 °С (depending on the design variant).

Sight flow indicators are used for a broad spectrum of control tasks: during transportation and storage of oil and gas products, in the water-supply and drainage systems, for the operation control of the pumping equipment, delivery of the liquid materials in the food industry, etc.



Design description

The sight flow indicator consists of corrosion resistant steel housing (or any other alloy) 08H17N13M2 (an analogue of AISI 316L). It’s possible to control the medium through the observation windows (one or more) on the housing. Due to the graphite or ftoroplast insulation the instrument is completely hermetically sealed. Material choice for this padding depends on the technological process conditions. For the improvement in the flow visibility for the transparent and clear compositions, instruments of the RIZUR-VIP series are equipped with additional mechanisms. Inside the housing, there can be an impeller (rotary table), a flap (vane) or balls.

Accordingly, when the medium passes the flow, the impeller starts to turn, the valve gate – to move back, and the balls – to move around. The stronger the flow – the quicker these processes occur. Impeller, a flap, and balls help identify low-speed flows and medium movement at a distance..
