Flow meter for plastic pipes in Zone 1 according to Atex 

June 04.06.2020, 1 | The flow meter Semiflow ExXNUMX Set from Sonotec is an intrinsically safe ultrasonic flow sensor with ballast. It is used for non-contact monitoring of liquids on small and medium-sized rigid plastic hoses in potentially explosive areas.

The Semiflow CO.66 PI Ex1 flow meters are protected against the risk of explosion from gases, vapors and liquids such as oil according to gas group IIB. They correspond to the equipment protection level (EPL) "Gb" for applications in 1 Zone in accordance with the Atex/Iecex standards.

An additional device according to IEC 60079-11 (Atex/Iecex) is the Barrier Box ST Ex1. This allows the intrinsically safe flow sensors to be used in potentially explosive areas with possible fire or explosion hazards (Zone 1, Group IIB). The device regulates the energy supply to the Sensor and thus prevents potential ignition pulses in the field. It provides all necessary power and data interfaces outside of the Ex zone.

Ultrasonic flowmeter in the semiconductor industry

The flow meters were specifically designed for applications such as highly accurate and non-contact flow and Volume measurement designed for abrasive, adhesive, corrosive and ultra-pure liquids. Due to their robust industrial design, they are already being used successfully in single wafer, cleaning and mixing systems, slurry lines, chemical supply and in lithography.

Pressure sensor innovations for digitization in measurement technology

The Semiflow flow meter is compact and based on the Clamp-on technology. This eliminates the risk of contamination and leakage. The Semiflow flow meter is available in eight sensor sizes for many hose sizes. The flow meter is suitable for PTFE, PFA, and other plastic hoses and plastic pipes.

Ultrasonic flow measurement

The development of the Semiflow flow meter is based on decades of expertise in construction contactless Ultrasonic flow sensors, especially for measurements in highly sensitive processes Medical Technology and biopharmaceuticals. There are particularly strict regulations with regard to safety-relevant components.

The flow sensor also developed performance features such as the implementation of a volume counter, high-precision real-time flow measurement of up to 400 l/min, the wide selection of industrial standard interfaces and the know-how in dealing with a variety of hose properties and hose geometries.

Tailor-made flowmeter for many media

17.03.2020 | Eletta measurement technology presents the EMF series, a new magnetic inductive flowmeter for many types of liquids. The volumetric measuring principle without moving parts in the product flow and the completely welded measuring tube make the sensors extremely robust and maintenance-free. The process connection via flange is always designed with the full pipe diameter. 

This avoids a pressure drop in the pipe and minimizes the performance losses in the system. The flow meters are suitable for conductive liquids, as well as media containing solids, contaminated or pasty and delivers results at high flow rates of up to 10 m/s.

The data transfer of the measurement takes place via Modbus RS485, Hart, GPRS or Profibus DP. The specified mains supply voltage is 110-240 VAC - an 18-36 VDC voltage supply is also available as an option Battery possible. The power consumption of the measuring device is low at less than 20 W.

Customized flow measurement for every application

A flowmeter of the EMF series can be design process-specific. Pipe diameters from DN10 to DN2200, installation lengths according to industrial standards, pipe linings made of polypropylene, hard rubber or PFTE for different process temperatures as well as measuring electrode materials also for aggressive media allow a tailor-made adaptation to the application of flow measurement.

Ultrasonic sensors for distance, distance and level

Thanks to the modular structure consisting of a tubular part with an integrated sensor and signal converter, there is EMF Flowmeters in an integrated design and as a version with remote evaluation electronics. This enables the flowmeters to be optimally adapted to difficult installation or operating situations.

Flowmeter for chemical to food industries

The many Variants The flow meters ensure the greatest possible flexibility for a wide range of applications. This is how a flow monitors Sensor of the EMF type in chemical process technology the volume flow of acids and bases as well as corrosive and abrasive media.

During the water treatment the devices are used to measure the flow of all types of liquids such as sewage and sludge. Dredging sludge, ore sludge and other media with a high solid content, such as those found in the metal and mining industry, are reliably mastered by the EMF sensor. The same applies to dyes, bleaches and other difficult process media used in papermaking. The CIP and SIP-capable flow meters from Eletta are also ideal for filling liquid food under hygienic conditions.

Ultrasonic flow meter with advanced data logger functions

June 05.06.2018, 1 | The data logger is a valuable tool for recording all data relevant to flow measurement. The 2 or XNUMX channel “Deltawave CF” ultrasonic flow meters from Systec Controls can now record additional values ​​via two analog inputs. This allows users to record any analog values ​​in the data logger of the measuring device or to pass the data on directly to a control system via RS232/Modbus without any time delay.

Depending on the application of ultrasonic flow measurement, it may make sense, for example, to record or forward pressure, temperature, level or other analog values. This is useful for analysis, for example Pump characteristics to record and evaluate the relationship between pressure and flow measurement.

All measurement data can be easily and clearly imported into Excel and evaluated. With this extension contributes Deltawave CF helps to recognize connections and easily identify potential sources of error in a complex system and save a lot of money. Even after a power loss, the device automatically starts recording data again without any manual intervention.

Precise mass flow rate measurement on small lines

May 19.05.2014, XNUMX | Designed for precise and cost-effective flow measurement of air and other non-explosive and non-corrosive gases Systec Controls Deltaflow C. Equipped with what is probably the smallest and fastest multivariable transmitters for industrial gas mass flow Measurement uses the very precise differential pressure measurement method.

The compact mass flow sensor is compared Compared to other measuring methods such as thermoanemometers, they are relatively insensitive to condensates, dirt and deposits such as pipe abrasion compressorsenoils. The installation and positioning of a plug-in probe is sometimes complicated, especially with small lines.

That is why there is now a screw-in probe in addition to theCompact venturi-Version for diameters from ¾ to 1 ½ “. Together with the display device, a measurement including totalizer can be set up very easily. The venturi is screwed into a pipe section with the male thread connections G ¾, G1, G 1 ½ and connected to the transmitter. The display device supplies the Venturi with voltage.

Measure the reliability of the mass flow rate 

The automatic zero point correction and the diagnostic function guarantee measurement reliability. Thanks to the modern microcontrollercontrol the practically maintenance-free and low-drift Deltaflow C offers an exceptionally high zero point stability with a large measuring range and high measuring range dynamics. Extremely fast Sensors record differential pressure, static pressure and temperature. The mass flow is measured up to 4000 times / s. The two analog outputs work independently of each other and can output pressure or temperature in addition to the mass flow.

typical Applications are compressed air monitoring and measurements in heating, air conditioning, ventilation technology as well as exhaust gas quantity measurement and combustion air control Engines or for process air monitoring.

Bopp + Reuther measures flow without electricity

06.02.2013 | Karsten Lehrke, Managing Director of Bopp + Reuther Messtechnik GmbH, Speyer, will be showing at the RBS Stutensee trade press days in Karlsruhe how flow can be measured without electricity and still communicated at the same time.

FAQ

What is mass flow?

Mass flow is a physical quantity of fluid mechanics, thermodynamics, electrical engineering or energy engineering. The mass flow defines the mass of a medium which is transported through a cross section in a certain time unit. The unit of the mass flow is given in kilograms per second (kg / s) or kilograms per minute (kg / min) and in the case of very slow flow rates also in kilograms per hour (kg / h).
