Flow meters for every industry and medium - by use of ultrasound and without media contact

As the technology and market leader in the field of clamp-on ultrasonic flowmeters and real time concentration and density monitoring as well as advanced process analytics using clamp-on ultrasound and inline refractometry , FLEXIM offers the best measurement solutions for any application and media in every industry.

Our measuring devices for determination of volume and mass flow, density and concentration are field proven in numerous industrial applications worldwide:

• Flow measurement and media detection within the Oil and Gas sector
• Flow and concentration measurement within the chemical industry
• Drinking water and sewage monitoring in municipal networks
• Thermal energy measurement and compressed air consumption monitoring within industrial and commercial buildings and plants
• Media contact free flow measurement and concentration determination within the food and beverage sector
• Highly hygienic flow measurement by principle within the production of pharmaceuticals
• Flow measurement at extreme temperatures within power plants
• Flow measurement of caustics and slurries without media contact within the pulp and paper production
• Flow measurement without media contact within the production of semiconductors
• Flow measurement of corrosive and solids containing media in the mining sector
• Contact free flow measurement of ballast water, fuel consumption and other processes on-board ships

Conventional measuring systems such as differential pressure meters, electromagnetic flowmeters, vortex meters or Coriolis mass flowmeters are subject to well-known disadvantages: Their installation requires costly pipe modifications - not only due to the installation costs themselves, but additionally those resulting from subsequent process interruptions. Due to the continuous media contact, wetted flow meters are also subject to increased wear - frequent maintenance intervals are particularly the case when measuring abrasive and corrosive media. These and other factors severely limit the cost effectiveness of wetted flow meters.

Our permanent and portable clamp-on flow meters are the ideal measuring systems even for the most challenging applications:

• Accurate and reliable flow measurement of liquids and gases over a virtually unlimited temperature range (from -190°C up to +600°C for liquids as well as -40°C up to +200°C for gases)
• Independent of pipe sizes (from 6mm inch up to 6m and beyond), materials - accurate and reliable measurements even at badly manufactured pipes (e.g. GRP) or pipes with inner linings – as well as independent of pipe wall thickness
• Independent of internal pressurization - no maximum pressure limitations, measurement starting at 3 bar at steel pipes and less than atmospheric pressure at plastic pipes
• High measurement accuracy even at very viscose liquids, slurries or wet gas (up to Liquid Volume Fractions (LVF) of 5%)
• Independent of gaseous entrainments and solids in liquids - ideal for the measurement of sewage and slurries due to patented HybridTrek® mode
• Unrivalled sensitivity and accuracy at flow measurement points with very low flow velocities down to a few liters per hour and less - no risk of leaks and thus ideal for flow measurement of corrosive and toxic media
• Simultaneous monitoring of mass flow, density and concentration by use of the clamp-on ultrasonic measuring system PIOX S
• All FLEXIM flow meters (permanent and portable) are additionally available as FM, ATEX and IECEx approved variants and are thus certified for usage in hazardous areas

FLUXUS and PIOX - Standard setting flow meters and measuring systems for inline process analytics

It’s our maxime to offer our customers the most reliable, accurate and suitable measuring system with the highest quality possible and to be a reliable partner with the best possible support and service . 
Our clamp-on ultrasonic flow meters, FLUXUS, our non-invasive density, concentration and mass flow meters, PIOX S, as well as our range of inline process refractometers for concentration determination, PIOX R, are engineered and manufactured according to highest standards.

Our FLUXUS ultrasonic flow meters for gases and liquids offer convincing advantages:

• Highest zero point stability and accurate measurement of even the lowest flow velocities due to careful matching of the transducer pairs according to their individual properties.
• No measurement drift as of internal temperature compensation within the transducer according to ANSI/ASME MFC-5.1.-2011 regulations. Temperature differentials between medium and transducers are automatically detected and compensated.
• Highest precision on the basis of individually calibrated ultrasonic transducers and transmitters. In conjunction with national research laboratories, FLEXIM has developed a leading patented calibration method that allows the sole calibration of the measuring system while eliminating all application relevant disturbances (e.g. uncertainties in pipe dimension, flow profile, etc.).
• One flow meter for all applications: FLUXUS offers highest flexibility in regard to pipe dimensions, materials and flowing media. With all calibration data stored inside the transducers, the measuring system is completely interchangeable - stock-keeping is reduced to a minimum.
• Highest protection: FLUXUS offers highest mechanical durability. The transducers are featuring stainless steel armored cables and mounting fixtures protecting them from the harshest conditions.
• Highest measurement quality even at extreme temperatures: As of the patented WaveInjector® transducer mounting fixture, our range of FLUXUS flow meters are capable of measuring precisely and reliable over an extremely wide temperature range from as low as -190°C up to +600°C
• No limitations: FLUXUS measures without a pressure limitation. For gases, measurement starts at 3 bar on steel lines and less than atmospheric pressure at plastic pipes.
• No maintenance efforts: Due to the non-existent media contact, FLUXUS flow meters are not suffering from wear and tear. As of our durable and long-term stable pipe wall coupling pads, conventional “regreasing” is not necessary at all.
• No process shut-downs: Installation of the FLUXS flow meter is done without pipe modifications and without process shut-down. For mounting only a minimum amount of time and personnel resources are required.
• Highest process safety: The FLUXUS flow meters don’t need any intrusion into the pipe. Measurement is taking place without media contact. Thus, there is alsono risk for leaks .

Media identification, density and concentration monitoring as well as mass flow measurement with PIOX S and FLUXUS HPI

Based on the principle of measuring the ultrasonic transit time for volume flow calculation, PIOX S additionally monitors the sonic velocity of the flowing medium. The sonic velocity is a substance specific property for many liquids and - in dependency of the mediums temperature - correlating to its density and concentration.
PIOX S thus enables the density, concentration and mass flow measurement without media contact. Especially for corrosive and toxic media PIOX S is the measuring system of choice. FLUXUS HPI makes use of this measuring effect when monitoring hydrocarbons. FLUXUS HPI measures the API gravity & number and can thus differentiate between various hydrocarbons, e.g. when distributing various gasolines in tank terminals. Additionally, the meter measures the mass flow rate of the flowing medium.

Inline concentration measurement with PIOX R

In contrast to PIOX S and FLUXUS HPI, PIOX R measures liquids optically by use of refractometry. PIOX R employs the in-house developed and patented transmitted light measurement principle. In comparison to conventional measuring methods, PIOX R is independent of deposits at the prism and thus immune to measurement drift . PIOX R not only increases the measurement quality but also significantly lowers necessary maintenance intervals and reduces associated costs.

Besides applications within the pharmaceutical and food & beverage sector, such as the monitoring of °Brix, Oechsle or Plato values, PIOX R also measures - in its PTFE coated product variant - the concentration of acids and caustics.
