High-frequency microwave pulses issued by the guided wave radar propagate along detection components (steel cable or steel rod) and met the media to be measured, since the dielectric constant of the mutation, causes reflections, a portion of the pulse energy is reflected back. Transmit pulse and the reflected pulse is proportional to the distance and […]

A guided wave radar level meter is a measuring instrument based on the time domain reflection principle. The electromagnetic pulse of the radar level meter travels at the speed of light along a steel cable or probe. When encountering the surface of the measured medium, part of the radar level meter’s pulse is reflected to

A company used our radar level meter to measure sulphuric acid and hydrochloric acid at ambient temperature and pressure, using two types of radar level meters, model RD-906, and RD-FMW11 respectively. The customer contacted us for help. Our after-sales engineer arrived at the site and adjusted the range of the radar level meter to a
Radar level transmitter measures acidic liquids Read More »
The traditional definition of an acid is a compound that, when dissolved in water, has a concentration of hydrogen ions in solution greater than the concentration of hydrogen ions in pure water. The pH of an acidic solution is less than the pH of water. Acids are generally acidic and can undergo neutralisation reactions with

Liquid ammonia is a colorless liquid with a strong irritating odor. As an important chemical raw material, ammonia is usually obtained in liquid form by pressurizing or cooling gaseous ammonia for transportation and storage convenience. Liquid ammonia is easily soluble in water and forms ammonium ions NH4+ and hydroxide ions OH- after dissolving in water,
