Excellent Resource for Finding Measurement & Control Products FAST!

find instruments fast
Find instruments fast!
Yokogawa Corporation of America, an industry recognized source for innovative process measurement and control products, has made available an easy to use product selection tool for those navigating through the company's extensive product offering. The Product Finder is a great time saver that enables a user to quickly locate product and technical information on Yokogawa products that meet the user's selected criteria.

Let's step through a quick example. You will see how this quick and easy to use tool saves time by navigating quickly to the website pages detailing products meeting your requirements.

The Product Finder is accessible through a number of links throughout Yokogawa's network of Reps. Clicking the link lands you on the start page of the Product Finder. For this example, I am going to search for a flow meter with the following characteristics:
  • Mass flow measurement 
  • Non-conductive liquid
  • Accuracy of 1%
  • Flow measurement device must have an integral transmitter
  • Tri-clamp connections

Above, I declared my location as United States. The next step, shown below, is to select "Flow" as the measurement parameter. You will see in the drop down menu that there are many measurement elements that can be selected, with Yokogawa products for each.

My selection of "Flow" returns a list of all the company's flow measurement devices, of which there are many (this cropped screenshot, shown below, only shows four, but there were many more) . This is where the selector really helps you. Instead of examining several or many different models, the user can focus the search by adding more product characteristics. You can see the list of prompting questions on the left side of the page. Answering these will narrow the search results to the show only the products meeting all the criteria specified by the user.

The next image (below) shows selections of all  my sample product attributes entered on the left column. Note that there is now only a single product that matches all of my sample criteria. The whole process took less than two minutes. By clicking on the "View More Details" button below the product image, I gain access to all of the available technical, support, and product data for my selected flow measurement device.

Choose Thermal Dispersion Flow and Level Technology for Your Next Application

Thermal Dispersion flow and level switches are found in continuous operation in the most demanding and critical process and plant applications. This technology is the most preferred solution in oil and gas upstream and downstream applications; wastewater treatment; chemical operations; power plants, including nuclear power; food and beverage; refineries; mining; metals; manufacturing and more. Whether your application is for flow, level, flow + temperature or level + temperature, there is an thermal dispersion flow and level switches are available to meet your needs.

The reasons for their popularity are clear. They were developed from more than 40 years of flow and level switch engineering and application experience to deliver the most reliable, repeatable, rugged and longest life industrial grade switch products found anywhere.

Thermal Dispersion technology uses the principle of measuring the heat loss, or cooling effect, of a fluid flowing across a heated cylinder. A typical flow element configuration uses two RTDs, sheathed in thermowells, separated by a gap. Heat is applied internally to one RTD relative to the other, creating a differential temperature between the two. This differential temperature is greatest at no flow conditions and decreases as flow increases, cooling the heated RTD.

Changes in flow velocity or immersion of the flow element into a liquid directly affect the extent to which heat is dissipated and, in turn the magnitude of the temperature differential between the RTDs. This differential is electronically converted into an electrical signal that can be used to trip a relay in flow or interface switch applications.

Since the relationship between flow rate and cooling effect is directly related to mass in gas applications, Thermal Dispersion technology, combined with advanced signal linearizing circuitry, is used to provide a highly repeatable and accurate measurement of gas or air mass flow rates.

Advantages to Using Thermal Dispersion

  • Precise performance accuracy
  • No moving parts
  • All welded design
  • All 316L stainless steel, Hastelloy, or exotic materials
  • Designed for heavy industrial environments
  • High liquid flow rate sensitivity
  • High temperature service
  • All liquids and gases

Additionally, models are available with 316L stainless steel wetted parts that are electro-polished to 20 Ra, with a sanitary flange process connection meet the sanitary requirements of the food, beverage, pharmaceutical and chemical industries. The instrument’s "no moving parts" design makes it ideal for monitoring the flow of syrups, fillings and other viscous media and product slurries. This design is suitable for both clean-in-place and steam-in-place applications.
