This probe is used to measure ammonia (NH3) in aqueous solutions. In an aqueous solution, ammonia is in a pH dependent balance with ammonia ions (NH4+-lonen). If the NH4+ ions are transformed into ammonia by the addition of a caustic solution, the probe will record the resulting ammonia. NH4+ ions as such will not be recorded. The ammonia sensor comprises a pH glass electrode and a reference electrode. Both electrodes are immersed in an electrolyte. The electrolyte is separated from the medium to be measured by a hydrophobic gas permeable membrane. The pH value of the electrolyte changes by NH3 gas permeating the hydrophobic membrane. This local change of the pH value is measured by the integrated pH electronic at a resistance. The advantage of the JUMO ammonia probe is the availability of pre-fabricated membrane caps. Manual attachment of the sensitive membrane is not required. The membrane cap of the JUMO probe is easily and quickly replaced as a compelete unit.

The disinfectant bromine offers a greater disinfectant effect at higher pH values compared to chlorine compounds while at the same time having a lower corrosive effect.Abreacted bromine solutions irritate the mucous membranes to a lesser extent and have a neutral odor.
The membrane-covered, amperometric sensor works on the three-electrode principle. The device is used for the online measurement of hypobromous acid (HOBr). Suitable bromination methods include free bromine (HOBr) as well as 1-bromine-3-chlorine-5.5-dimethyl-hydantoin(BCDMH).

These membrane-covered amperometric sensors are used to measure the concentration of chlorine dioxide or ozone in aqueous solutions (e.g. drinking water, swimming pool water, industrial water, process water, and cooling water). The sensor for chlorine dioxide can be used to measure chlorine dioxide from chlorite/chlorine and chlorite/hydrochloric acid plants. The sensor for ozone can be used to measure electrolytically generated ozone among other things. The sensors are not suitable for detecting the absence of chlorine dioxide or ozone. The integrated electronics of the sensors provide a temperature-compensated current signal of 4 to 20 mA. A downstream device (indicator, controller, recorder, PLC, etc.) is used for calibration. The sensors can be connected directly to a suitable display and control device

The basic operation of Coriolis flow meters is based on the principles of motion mechanics. As fluid moves through a vibrating tube it is forced to accelerate as it moves toward the point of peak-amplitude vibration. Conversely, decelerating fluid moves away from the point of peak amplitude as it exits the tube. The result is a twisting reaction of the flow tube during flowing conditions as it traverses each vibration cycle. ACoriolis meter is based on the principles of motion mechanics. When the process fluid enters the sensor, it is split. During operation, a drive coil stimulates the tubes to oscillate in opposition at the natural resonant frequency. As the tubes oscillate, the voltage generated from each pickoff creates a sine wave. This indicates the motion of one tube relative to the other. The time delay between the two sine waves is called Delta-T, which is directly proportional to the mass flow rate.

Electromagnetic flowmeters have been used throughout industries for more than 60 years. These meters are applicable for all conductive liquids, such as water, acids, alkalis, slurries and many others. Typical applications are monitoring of liquids, filling, dosing and precise measurement in custody transfer. The two million magmeters we`ve sold since 1977 need no maintenance and offer seamless system integration into your processes. In the industrial environment, electromagnetic flowmeters are primarily used in water management and in the processing, life sciences and food industries. In tunnel construction and mining, robust magmeters are often the only option for measuring highly abrasive ore slurries with entrained solids, sand-water mixtures, filler materials or bulk solids with the required accuracy.
