What products are involved in this article?
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 a Mettler Toledo design to provide a reliable and secure connection between a sensor or probe and the industrial process it's monitoring or controlling, even in demanding process environments. This connection is widely used in industries such as pharmaceuticals, food and beverage, chemical manufacturing, and water treatment, where precise measurement and control of process variables play a crucial role in ensuring high-quality products and safety.


2. Rheonic sensor Ingold process connection


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


The Ingold-compatible version of the Slimline SRD (SRD-SLP) inline viscosity and density meter, as shown in Figure 1, is specifically designed to allow mounting the sensor probe into an Ingold DN25 adapter for the installation of hygienic instruments.

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.

In addition to the SRD, the Ingold DN25 installation needs other parts to be installed in a tank or a pipe. The following image shows what is needed and their parts description, The SRD-SLP Ingold DN25 is only provided by Rheonics.

4. Installation of DN25 Ingold sensors


Ingold connections are commonly used in bioreactors. Since the adapter must have a self-draining orientation to prevent liquid from stagnating, it can be installed from the side or on top of a tank (Figure 5). The bottom-side installation option is also valid and is mostly used with double-jacket tanks (Figure 7), but it may pose a problem in terms of cleaning.


Consider that the SRD sensor is generally not recommended for installation in reactors, tanks, or vessels with mixers or stirred fluids. The undefined and changing flow around the sensing element can affect the readings. Instead, the SRD is better suited for installation in recirculation lines (Figure 7), where the flow rate is more constant.


We can see some examples of installations of this sensor in the following images.
