Applications

Fertilizer

Dynatrol® Density Measurement Systems are used extensively with ammonia solutions for measurement and control of density, specific gravity, or percent concentration. Dynatrol® Bulk Solid Level Switches are used on bins and hoppers for high, mid and low point detection.

  • Eliminate multiple hand sampling when mixing
  • Real time percent concentration measurements of ammonium hydroxide with no effects from pressure changes or pipe vibration
  • Virtually no maintenance costs

Density Measurement

The Dynatrol® CL-10HY Density Cell and Series 2000 Digital Density Converter are used around the world for measurement of Anhydrous Ammonia and ammonia solutions. Our density products can measure and display specific gravity , density or percent concentration of ammonia products. The density cell measures the characteristics of a vibrating tube and temperature of the product. The electronic converter then calculates the percent concentration and density of the solution inside the Density Cell. Our Density Systems are used for measurement on:

  • Ammonia Solutions
    • Ammonia
    • Ammonium Hydroxide
    • Ammonia Liquor
    • Ammonia Water
    • Ammoniacal Liquor
    • Aqua Ammonia
    • Aqueous Ammonia
  • Ammonium Nitrate
  • Anhydrous Ammonia
  • Diammonium Phosphate
  • Nitric Acid
  • Phosphoric Acid
  • Urea

Bulk Solids Level Detection

Our Bulk Solid Level Switches are used for determining the level of powders or granulars in a bin or hopper. Dynatrol® level switch products have very stringent hazardous location ratings including Class 1, Division 1. Groups A B C and D. They can be used for level detection of any ammonium salt that does not attack stainless steel. These level switches can be manufactured with various sensitivities. The lightest can detect powdered polystyrene foam and the heavy duty products can be used on things as difficult as crushed concrete or rock.

Sulfuric Acid

Dynatrol® Density System can be used to measure sulfuric acid. The sulfuric acid application software is written to use the temperature and density information that comes from the CL-10HY cell to calculate product baume, density at a reference temperature, specific gravity and percent concentration.

Automation Products, Inc. uses the same reference tables used by sulfuric acid manufacturers to cross check results generated by our sulfuric acid software. The CL-10HY and Series 2000 combination have been used to measure sulfuric acid for automobile batteries, and low concentration sulfuric acid mixing. It has also been used to measures high concentration sulfuric acid in chlorine drying towers as well as very high sulfuric acid concentrations in mixing and make up applications. The Dynatrol® Density Cells can be supplied with tantalum media contact parts as well as Carpenter 20 and other alloys that can be chosen for your specific application.

Pipeline

Dynatrol® Density Systems are used worldwide in pipeline applications for measurement and control of density, specific gravity, API gravity or percent concentration. Typical applications are custody transfer or interface measurement and may include crude oil, refined products or various other chemicals.

Dynatrol® Density Cells are used to measure the liquid being transported in the pipeline. The Cell’s operation is extremely accurate and dependable, requiring no pressure compensation.

Working with the Density Cell, the Dynatrol® Digital Density Converter translates the product density and temperature readings into the customers’ required units of measurement. For example, if a United States pipeline requires the American Petroleum Institute (API) scale or a Canadian Pipeline requires output in kilogram per cubic meter (kg/m 3), Dynatrol® electronics are programmed for each application’s specific measurement needs.

The Dynatrol® Systems are user-friendly. Converters come pre-programmed for simple calibration. Many Dynatrol® Density Cells have sustained accuracy in the field without need of service for over 20 years!

Starches

The Dynatrol® CL10-HY Density Cell and Series 2000 Density Digital Converter can be used to measure corn or potato starches.

The starch application software is written to use temperature and density information that comes from the Cl-10HY cell to calculate product baume, density at a reference temperature and specific gravity. Automation Products, Inc. uses the same reference tables that are used by starch manufacturers to cross check results generated by our starch software.

The CL-10HY and Series 2000 combination has been used in processes where starches are used as coatings as well as starch make up tanks and starch dilution applications.

Nitric Acid

The Dynatrol® CL10-HY Density Cell and Series 2000 Density Digital Converter can measure the temperature and density of a nitric acid process stream.

How it works: The Series 2000 Digital Density Converter processes basic information from the Density Cell to calculate density at a reference temperature. The process value can be used to calculate the specific gravity, Baumé and percent concentration. This information is made available to the operator or process engineer.

The standard Series 2000 has an analog output corresponding to either of these process variables. Optionally, it can be programmed to have two analog outputs that can be calibrated for any two process variables (Density, Temperature, Baumé, Specific Gravity, Percent Concentration).
