WOL-34NS - Rheonics

Description

Rheonics WOL-34NS accessory is a NPT weldolet used for installation of SR sensors in 2” pipes. This weldolet is designed to ensure that the Rheonics SR-sensors sensing element is fully immersed in the flow, thus providing the correct measurement conditions using this type of installation.

Why use this part?

  • This part is often used for sensors installation on a line or tank.

  • Commercially available weldolets are not well suited for the standard 3/4“ NPT version of SRV or SRD as they tend to create large dead zone around the sensing element, thus giving unreliable measurements.

  • WOL-34NS has a specifically designed with shortened thread and height, ideal for 3/4“ NPT version of SRV and SRD.

  • Plugging of the gaps (yellow highlighted in figure below) affects the sensing element. This affects the measurement accuracy and stability.
