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.

The CL-10DJ series of level switches are used for measurement of high, intermediate, or low level detection of bulk solids in mining applications such as coal dust collection and transportation.

The Dynatrol® CL-10DJ series level switches complete with EC-501A control unit, are used for measurement of high, intermediate, or low level detection of bulk solids in mining applications such as coal dust collection and transportation.

CL-10DJ level probes withstand buildup and are suited for harsh mining environments. Constructed in stainless steel, probes are also available in corrosion and abrasion resistant steels to match your difficult applications.

The EC-501A control unit contains circuitry that performs frequency analysis, voltage analysis and makes decisions regarding the actual level switch point. This added technology reduces false tripping and makes our level measurement more dependable.

Mining Industry applications may include:

  • Alum Pellets
  • Alumina
  • Aluminum Chips
  • Aluminum Hydrate Powder

Dynatrol® Liquid Level Switches are used in storage tanks or vessels at the point where level detection is needed. Dynatrol® Density Systems are commonly used on fructose and juice applications throughout the industry.

Liquid Level Detection

Dynatrol® CL-10GH Liquid Level Detector can be used in Beverage Industry applications where it is necessary to know the high. mid or low level point of fructose, corn syrup or sugar liquor in a tank or other vessel. The Dynatrol® level probes are inserted into the storage tank or vessel at the point where the reading needs to be taken. When the product reaches the level probe the probe will detect its presence and close a contact. This contact closure can be used to turn on an alarm, a light or can be used as a computer input. The contact arrangement of the Dynatrol® level switch lends itself to use in either high or low level applications.

Density Measurement

The Dynatrol® CL-10HY Density Cell and Series 2000 Digital Density Converter can be used to measure fructose corn syrup, high fructose corn syrup, sucrose syrup, or dextrose. The Dynatrol® Density System uses temperature and density information from the CL-10HY cell to calculate degrees BRIX, Baumé or density at a reference temperature. Automation Products Inc./Dynatrol® software uses the same reference tables that are used by sugar growers. The CL-10HY and Series 2000 combination has been used in processing corn syrup as well as other syrup applications such as soft drink bottling and mixing. For many years the Dynatrol® Density System has been used for fructose applications within the Food Industry.

Evaporators/Concentrators: Vegetable Juices

The Dynatrol® CL-10HY Density Cell and Series 2000 Digital Density Converter are used to measure density or percent concentration of dissolved or suspended solids for condensed juices, vegetable juices and broths in the beverage or food industries. Concentration of vegetable juices can be measured by the Dynatrol® Density System and the results can be used to control the evaporation process.
