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.
