These variants of the sight flow indicators (observation windows) are manufactured in accordance with the client’s requirements to the diameter and are used for operation with 12 MPa pressure (RIZUR-VIP-8).

Maximum process temperature is +260 °C.

RIZUR-VIP-7 and RIZUR-VIP-8 consist of an observation window and a housing, manufactured from one of the following materials:

stainless steel 07Х18Н13М2 (SUS316L),
nickel steel,
brass.

In order to achieve greater flow visibility, sight flow indicators RIZUR-VIP-7 are equipped with additional options – screen wiper and LED lamp. The screen wiper is used when there’s a necessity to enhance glass transparency. LED lamp can have height adjustments and optional rotation angle – it’s used for increasing the illuminance.
