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 GEA Varinline connection, its uses, and installation options.

1. Overview

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

The Varinline flush version of the SRD inline density and viscosity meter, as shown in Figure 1, is used to mount the sensor probe into different kinds of GEA Varinline housings which are used for the installation of hygienic instruments. 

SRD sensor with Varinline process connection can use GEA housings to remove dead zones around the sensing element, ensuring easy cleaning and sterilization through standard CIP (Clean in place) procedure. For example: 

• GEA Housings - T, allows the SRD to be installed in-line in smaller pipes (DN25 minimum) than those available with other process connections, without the use of Rheonics flow cells. 

• GEA tank connection flange - P, allows a flush installation of the SRD in tanks.

• GEA Housings connection flange - U and US, allows installations of the SRD in Tee or elbows.

The SRD Varinline has an EHEDG certification on the process connection size B, F, N, and G. You can find the certificate here.

Suitable GEA housings or installation options for the SRD Varinline sensor:

• GEA Housing DIN 11850 - DN25

• GEA Housing DIN 11850 - DN50 or bigger

• GEA Housing Sight glass

• GEA tank connection flange

2. Installation examples

2.1 GEA Housings (Type T) 

2.2 GEA Tank connection flange (Type P)

The SRD can be installed in the Varinline tank connection flange which is welded into vessels with a wall thickness up to 20 mm to avoid dead zones in a hygienic installation.

Another installation option for the tank connection flange is using an SRD Long Insertion probe, this is very useful when you need a longer immersion of the sensing element in the tank.

2.3 Other Varinline process connections

The SRD Long insertion probe is compatible with Varinline housings connection flanges F, N, G type U and U-S, useful for installation in Tee or elbow pipes.

3. What is Varinline?

VARINLINE is a trademark of GEA for a range of in-line control and measurement technology for hygienic process connections. It allows the installation of control and measuring instruments in piping systems without any dead spaces, which is important in applications where hygiene is critical, such as the food and beverage industry.

VARINLINE housings are available for all pipe sizes and can accommodate a variety of instruments, including pressure gauges, temperature sensors, and flow meters. The housings are self-draining, which helps to prevent the build-up of contaminants. They are also CIP/SIP-able, which means that they can be cleaned and sterilized without the need to dismantle them.

VARINLINE is a popular choice for a variety of hygienic process applications, including:

• Food and beverage processing

• Pharmaceutical manufacturing

• Biotechnology

• Cosmetics production

• Water treatment

It is a reliable and cost-effective solution for the monitoring and control of process parameters in hygienic environments.

Here are some of the benefits of using VARINLINE:

• Hygienic design: VARINLINE housings are designed to prevent the build-up of contaminants, making them ideal for use in hygienic environments.

• CIP/SIP-able: VARINLINE housings can be cleaned and sterilized without the need to dismantle them, which helps to ensure the safety and quality of the product.

• Wide range of applications: VARINLINE is a versatile solution that can be used in a variety of applications, including food and beverage processing, pharmaceutical manufacturing, and biotechnology.

• Reliable and durable: VARINLINE housings are made from high-quality materials and are designed to withstand the harsh conditions found in industrial environments.

If you are looking for a reliable and cost-effective solution for the monitoring and control of process parameters in hygienic environments, VARINLINE is a good option to consider. Rheonics provides EHEDG certified inline process viscometer SRV and inline process density meter SRD with Varinline process connection to work with GEA Varinline adapters. The sensors are also available with EX certifications where needed. Standard sensors are available in Stainless steel 316L and for corrosive environments in Hastelloy C22.
