OPTIFLUX - One for all applications
With just one signal converter and the widest range of flow sensors, the OPTIFLUX covers all applications, from a simple water measurement to corrosive or abrasive products or even pulp in the paper industry. Simplified engineering, procurement and inventory lead to cost-savings for the user.
This new concept marks a new era, and is the result of more than 40 years' experience in electromagnetic flowmetering.

Sets the standards in electromagnetic flowmetering
Using brand new technology has enabled us to increase the measuring performance of OPTIFLUX even further. These improvements are particularly useful where today's meters begin to capitulate. Examples of this include very low conductivity, measurement of rapid product changes with corresponding changes in pH or the measurement of pulp in the paper industry. This increase in performance was possible by a 30-fold improvement in the measuring technology components. Here we exploited all known optimization potentials.

Advantages of KROHNE electromagnetic flowmeters
Electromagnetic flowmeters can be used in almost all branches of industry for the measurement of liquids (with or without solids content) pulps, pastes and other fluids that have a specific minimum of electric conductivity.  Superior electronics give you superior results - reliable and repeatable even under difficult process conditions, while quality manufacturing guarantee years of trouble-free use.  At KROHNE, all electromagnetic flowmeters are wet-calibrated by direct comparison of volumes, the most accurate calibration method of all. The KROHNE calibration rig is the world's largest and most accurate.  Compared with other measurement methods, electromagnetic flowmetering offers the following particular advantages:

• Measurement independant of pressure, density, temperature and viscosity
• Short inlet and outlet runs
• Free pipe cross section
• No additional pressure losses
• No moving parts
• Any desired installation location
• Measurement span 100:1
• High accuracy - up to ± 0.2 % of actual value

The liner and the electrodes of the flow sensors are available in various materials that will match almost any application.

Ultrasonic flowmeters (UFM's) find universal use for non-contact measurement of all fluids and gasses in which ultrasonic waves can propagate. The principle of measurement is based on ultrasonic transit time.
All our ultrasonic flowmeters are calibrated on the world's largest and most accurate calibration rig.

The Highlights of KROHNE's Ultrasonic Flowmeters:

• High measuring accuracy independent of viscosity, temperature and conductivity
• No pressure loss through the smooth metering
• tube and no obstructions to flow
• Exact calibration by direct volume comparison
• Intrinsically safe version to European Standard for Zone 0
• Low operating cost thanks to low power consumption and zero maintenance

All KROHNE ultrasonic flowmeters operate using the transit-time differential method.

Industry Specific Solutions
OPTIMASS has been specifically designed to overcome metering problems in notoriously difficult applications within the pharmaceutical, chemical, food and beverage industries.

KROHNE extends calibration facilities to meet customer demand
Seven state-of-the-art calibration rigs costing more than £500,000 have been installed at KROHNE's Coriolis mass flowmeter worldwide manufacturing and service facility in Wellingborough to meet the growing customer demand for the revolutionary OPTIMASS range. The rigs DN 15 to DN 250 are approved according to EN 17025 by UKAS.

No limits with tube materials
Titanium, Hastelloy, or Stainless Steel allow straight tube metering for almost any process.

No limits with flow
From 0.3 to 2300000 kg/h with a full range of meters for low and high flow applications.

No limits with measured product
High viscosity, particulate matter, inhomogeneous mixtures, normal entrained air, have little effect on the accuracy of the measurement.

No limits with installation
Support on the process pipe or the meter body, without the need for accurate positioning. A complete range of process connectors for all existing and future installations is available.

No limit with electronics
OPTIMASS has been designed with all new electronics, which incorporates Front End signal processing that is permanently mounted to the meter. This provides high speed and low noise measurement, as well as remote connection to the signal converter up to 300 m. Dual redundancy of configured data, calibration constants etc ease maintenance.

No limits with applications
KROHNE can provide metering solutions whatever your requirement including: Flow, Density, Concentration and Temperature.

Variable area flowmeters from KROHNE offer not only the maximum possible accuracy but also maximum reliability. A wealth of experience and an intelligent quality assurance system enables us to place our VA meters in applications inaccessible to other manufacturers such as nuclear power stations where safety is critical.
Variable area flowmeters feature an upright tapered measuring tube, wider end up, in which a specially shaped float moves freely up and down.
The medium flows through the tube from bottom to top. In so doing, it raises the float until there is an annular gap between the wall of the tube and the float and equilibrium of the forces applied to the float has been achieved.

The all-in-one solution
OPTISWIRL 4070 C is the first vortex flowmeter with integrated pressure and temperature compensation in 2- wire technology. OPTISWIRL 4070 C provides accurate measurement of operating, standard volumetric and mass flow of conductive and non-conductive liquids, gases and vapors even with fluctuating pressures and temperatures.

Clean alternatives with KROHNE:
Climate change affects us all. All over the world people are researching environment-friendly fuels such as bioethanol or biodiesel. The main focus of research is the car and fuels which do not increase CO2 emissions. It's important that we start now. After all, one of the earliest cars, the world-famous Ford Model T was originally powered by  ethanol before Henry Ford switched to mineral-based fuels. Biodiesel presents a convincing alternative because not only is it CO2 neutral, but it is also sulfur-free, biodegradable and has good lubrication qualities. The challenge is to create manufacturing processes for alternative fuels that are CO2 neutral while  keeping operating costs low. Achieving these goals requires precise maintenance of pressures and temperatures, careful dosing of raw materials and precise measurement of material flows. Intelligent measuring technology provides plant managers with the best tool for precisely controlling these processes.

KROHNE moves with the times and offers innovative measuring technology for efficiency in bioethanol and diesel production processes. With a wealth of measuring devices for the critical points in the process, KROHNE ensures that the CO2 balance is correct not only in the engine combustion process, but also during manufacture. The spectrum of products ranges from classic flowmeters in xxxx to reliable radar level meters in storage silos and innovative mass measuring devices for fermentation and distillation processes.

KROHNE measuring technology solutions for your biofuel facility
Modern facilities for manufacturing biofuels are models of efficiency: By-products are either reused in the process or are recycled for use in sections of the process are optimized to maximize efficiency. But there is still plenty of room for improvement. Researchers world-wide are investigating methods for increasing the yield to bring these facilities to maximum production. Plant operators need full, real-time information about the performance of each single component in their production facility. Measuring technology delivers this information.

And this technology must not only deliver precise data, but perform robustly and reliably for years and years. That's why leading biofuel producers have been choosing KROHNE's experience and expertise for many years. In state-of-the art biodiesel and bioethanol production facilities, positioning KROHNE devices for measuring flow, fill level, temperature and pressure located at a wide variety of measuring points, ensures an efficient, safe and cost-effective process.
