Sight flow indicator RIZUR-VIP-5

Sight flow indicators RIZUR-VIP-5 have cylinder housing and the following variants of process connection: thread (male or female) or for welding. Sight flow indicators RIZUR-VIP-5 can have an impeller or an observation window. Maximum pressure for these design variants - up to 1.6 MPa.

RIZUR-VIP-5 — sight flow indicator with thread or welded process connection. They are used at facilities that require visual control of the operating media. They are manufactured with the diameter requested by the Customer. Operating pressure – up to 1.6 MPa. NPO RIZUR can also manufacture customized variants operating with temperature up to + 450°C.

Sight flow indicator has a housing made of 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).

This indicator has a cylinder housing with an observation window for visual control of the flow. In order to achieve greater flow visibility, sight flow indicators RIZUR-VIP-5 are equipped with additional option – impeller (rotor). When the measured media passes through, the impeller rotates - this allows to observe low-speed flow and see measured media movement from a distance.

Sight flow indicators RIZUR-VIP-5 can also have a scale or observation window backlighting.

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