SRD Inline density and viscosity meter.

What is the purpose of this article?
To give an overview of the SRD inline density and viscosity meter with Ingold process connection, its uses, and installation options.

1. Overview

The Ingold process connection is designed by Mettler Toledo and is used to provide a reliable and secure connection between a sensor or probe and the industrial process pipeline, tank or reactor. It is often used in industries like pharmaceuticals, food and beverage, chemical manufacturing, and water treatment.

2. Rheonics Inline Density and Viscosity Meter with Ingold Process Connection

SRD probe configuration

SRD is a Rheonics sensor for inline density and viscosity measurement. Read more on SRD here.

Rheonics offers the SRD-X6 slimline probe as a sensor probe variant compatible with Ingold connection size DN25. The probe, shown in Figure 1, is customizable in insertion length (A code) with minimum insertion of 110 mm, and supplied with a retaining ring and a nut as also shown in Figure 1. The probe order code is SRD-X6-Axxx-BI25, where Axxx indicates the length in milimeters; e.g., A110 means 110 mm insertion length.

Installation requirements

The Rheonics SRD requires two installation criteria to ensure repeatable and reproducible readings while maintaining the configured accuracy.

• Have the SRD sensing element (shown in Figure 2) always immersed in the fluid.

• Avoid deposits and dead zones around the sensing space.

Rheonics SRD measures fluids in static and dynamic conditions up to approximately 10 m/s of fluid speed. It is also robust to external vibrations, thanks to the Rheonics patented BTR technology, while bubbles in the fluid and high speed mixing fluid regimes can cause noise in data. In these cases, filters can be applied as an attempt to obtain more stable readings or change of installation is suggested, such as in recirculation line, where fluid behaviour is better defined.

Installation port

For installation in tanks, reactors, or pipes, the SRD-X6-Axxx-BI25 requires:

• Proper socket selection: A G1 1/4 male threaded connection for the probe's nut.
• Adequate sealing: An O-Ring 20x2.5 mm (delivered by Rheonics in FKM).
• Correct probe insertion length: The probe should be ordered with the correct insertion legnth A, such that when installed in the socket, the sensing element is always wetted and away from dead zones during measurements. 

As shown in Figure 1, the probe is delivered with the retaining ring, nut, and O-ring, thus only requiring the welded port (socket). Review the detailed dimensions of the SRVDIngold connection to make sure the proper socket connection and length are used for a smooth installation.

Suggested off-the-shelf sockets for installation are those offered by Mettler Toledo, such as the straight socket 40/DN25 or the titled or angled socket 40/DN25/sch 3.1.

4. Installation of DN25 Ingold sensors

The versatility of Ingold connections allows for various installation points on a tank or reactor.Installations from reactor's wall or top are highly common and convenient because these allow for a self-draining orientation, thereby chances of deposits in the dead zones are minimize. Installation from reactor's bottom is particularly utilized in double-jacketed designs but require careful consideration as this position inherently poses challenges to effective cleaning and maintenance access. Next Figures illustrate the flexibility of the Ingold process connection used in the Rheonics SRD-X6 variant.
