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.

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!
