NPT 3/4”-14 weldolet for 2.5” or larger pipes and tanks - WOL-34NL

Rheonics WOL-34NL weldolet

Description

Rheonics WOL-34NL accessory is an NPT weldolet used on 2.5” or larger pipes and tank installations. 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.

Specifications
Sensor connectionNPT 3/4”-14
Installation requirementWelding
Material316L
Maximum Pressure500 bar (7500 psi)

Why use this part?

  • This part is often used for sensor probe 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 due to potential fouling/deposit intruding onto the sensing element.

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

  • Plugging of the gap in a standard off-the-shelf NPT weldolet (yellow highlighted in figure below) affects the sensing element. This affects the measurement accuracy and stability.
