Dynatrol® Density Systems are used on many applications in Petroleum Refineries, Sugar Refineries, Sugar Cane Cutting Mills and Bio-Refineries. Dynatrol® Bulk Solids Level Swtiches are used in Bio-Refineries to measure grain or natural cereals in hoppers.

Density Measurement

Dynatrol® Density Cells are used in Petroleum Refineries and water treatment withing those refineries on applications including:

  • Butane
  • Caustic Soda
  • Diesel Fuel
  • Gasoline
  • Jet Fuel
  • Kerosene
  • Propane
  • Sulphuric Acid
  • ... and many more

Sugar Refineries and Cutting Mills use Dynatrol® Density Cells to measure the concentration of sugar syrups and various chemicals used in sugar processing to maintain quality assurance standards.

Bio-Refineries, producing ethanol from corn, utilize Dynatrol® Density Cells primarily for measuring the density of the mash. The mash is ultimately processed into “beer” and further processed into ethanol.

Bulk Solids Level Detection

Dynatrol® CL-10DJ series are used in Bio-Refineries to measure grain levels in hoppers or the level of natural cereals produced from the biomass.

Ammonium Hydroxide

Dynatrol® Density Measurement Systems are used extensively for measurement and control of density, specific gravity, or percent concentration with Ammonia solution, also known as ammonium hydroxide, ammonia water, ammonical liquor, ammonia liquor, aqua ammonia, aqueous ammonia, or simply ammonia.

  • 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

Automation Products, Inc. was approached by a chemical company to devise a solution for online measurement of an ammonia solution. The process is describer below.


The chemical company needed online measurements while mixing anhydrous ammonia with water. Their pressurized ammonia was bubbled into a mixing tank with ultra pure water, and a sample stream was constantly pumped from the bottom of the tank to give a real time reading of percent concentration for aqueous ammonia.


The chemical company chose a Dynatrol® Density System to solve their problem. The Dynatrol® Density Meter has the Temperature vs. Density vs. Percent concentration curves programmed into the Series 2000 Digital Density Converter. The density meter provides 4-20 mA signals to the chemical company’s control room for percent concentration and temperature of the ammonia and water solution. Since the Dynatrol® Density Meter outputs percent concentration, there was no need to program a complicated set of algorithms into the DCS control system to calculate percent concentration from density.

After months of comparing hand sample measurements to the measurements of the Dynatrol® Density Meter, the company found that the Dynatrol® Density Meter correlated directly to the hand measurements. The company now uses the Dynatrol® Density System in the control of the mixing process. This eliminates the bi-hourly hand sampling that technicians would have to perform.
