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

Sight flow indicators RIZUR-VIP-2 and RIZUR-VIP-3 have the following process connection variants: thread (female or male) or for welding. These indicators can also have an impeller, a flap, balls or only have an observation window. RIZUR-VIP-2 has mounting openings not at the center of the housing. RIZUR-VIP-3 has mounting openings at the center of the housing.


RIZUR-VIP-2 and RIZUR-VIP-3 — sight flow indicators with thread or welded process connections. They are used at facilities that require visual control of the operating media. They are manufactured with the diameter requested by the Customer. They are used for pressure of 1.6 MPa, 2,5 MPa, 4,0 MPa. NPO RIZUR can also manufacture customized design variants of RIZUR-VIP-2 and RIZUR-VIP-3 for pressure of 6,3 MPa, 10,0 MPa, 16,0 MPa and temperature up to + 250°C.

Sight flow indicators RIZUR-VIP-2 and RIZUR-VIP-3 housings can be made from the following materials:

  • stainless steel 03Х16Н15М3 (an analogue of AISI 316L),
  • stainless steel 08Х17Н13М2 (an analogue of AISI 316),
  • stainless steel 08Х18Н10 (an analogue of AISI 304),
  • brass,
  • other materials (on request).

The housing of sight flow indicators RIZUR-VIP-2, RIZUR-VIP-3, RIZUR-VIP-4 have an observation window that allows visual control of the flow. RIZUR-VIP-5 has a cylinder form made from tempered or borosilicate glass. RIZUR-VIP-2 has mounting openings located not at the center of the housing. RIZUR-VIP-3 flow indicators have mounting openings located at the center of the housing. In order to achieve greater flow visibility, RIZUR-VIP-2 and RIZUR-VIP-3 are completed with additional options, such as an impeller (rotary table) or a flap (vane). Maximum pressure for these design variants – up to 0,6 MPa. RIZUR-VIP-4 has balls or an impeller available while RIZUR-VIP-5 only has an impeller. Moreover, the design variant of RIZUR-VIP-4 with balls can only be installed with an observation window facing upwards. When the measured media passes through, the impeller starts to turn and the flap to move back – this allows visual control of low-speed flows and media movement from a distance.

Sight flow indicators RIZUR-VIP can also have a scale and observation window backlighting.

Insulation can be made of graphite, ftoroplast, NBR or Viton. These materials ensure complete containment of the device, the choice between them depending on the conditions of the technological process.

OOO “NPO RIZUR” designs and manufactures sight flow indicators RIZUR-VIP-2 and RIZUR-VIP-3 of any non-standard configurations, including tee-typed and angled variants, made in accordance with the technical requirements of the Customer.
