Krohne Messtechnik - Chemical Process Measurement Instrumentation

Krohne is a leading system provider in the field of industrial process measurement instrumentation. Krohne provides water analysis, volumetric and mass flow meters, level gauges, and pressure and temperature measurement.

We have been active in the chemical industry for over 85 years and help make processes more efficient, more reliable and more economical. Krohne provides complete solutions, consultancy services and other services for all your process automation needs.

Measurement instruments for chemicals

Our field-proven measurement instruments cover a wide range of applications, such as bulk chemicals, petrochemicals and plastics, and fine chemicals.

Our wide coverage is achieved by innovative Krohne developments. These include measuring tubes made of materials such as high-performance ceramics with leak -proof Cermet electrodes, or titanium and tantalum measuring tubes and housings made of stainless steel or aluminium. There is also Ex protection for all zones and ingress protection up to category IP 68.

Process measurement instrumentation certificates

It is not surprising that leading calibration authorities use Krohne instruments as their master meters. Enabling the users to meet both today’s and future demands, Krohne holds nearly all certificates required around the world, including ATEX, SIL, CENELEC, MID, PED, ISO/IEC, GOST, FM, CSA and NEPSI.

In addition, Krohne has developed the unique 3 x 100%-diagnostics, allowing for indicating application issues and errors early and independently.

Krohne is the first and, to date, the only manufacturer to offer its customers complete application and process diagnostics as well as an accuracy and linearity test (out-of-spec diagnostics) in addition to the usual device diagnostics.

Flowmeters for process monitoring

Using the 3 x 100%-diagnostics with the OPTIFLUX electromagnetic flowmeter turns this instrument into much more than just a flowmeter, it monitors the process and provides the user with valuable information. These diagnostics along with knowledge of the process allow for easy recognition of:

• Gas bubbles
• Electrode corrosion, deposits on electrodes
• Short-circuit
• Low conductivity
• Partial filling of measuring tube
• Liner damage
• External magnetic fields
• Disrupted flow profile

During the out-of-spec test, a determination is made as to whether the device is still within its specifications. In particular, the accuracy is tested by feeding a test signal. The linearity of the device and the accuracy of the field current with which the magnetic field is generated are also checked.

Modular electronics for the chemicals industry

Chemical companies are facing various challenges, such as structural change, globalisation and tapping into new markets, not to mention the demand for improved productivity and quality, as well as constantly increasing safety requirements and new legal requirements.

Whether during installation, commissioning, operation or communication – high-end technology only makes sense if it is simple and convenient for the customer to access.

That is why Krohne’s development and application engineers have worked for years to develop a modular electronics concept that takes into account all requirements of the chemical sector in terms of signal inputs and outputs.

It features a uniform user interface to speed up the commissioning of the devices and hence reduces training requirements to a minimum thanks to the high degree of modularity.
