Solution for partially filled pipes The TIDALFLUX 2000 flow sensor with integrated and non-contact capacitive level measuring system provides accurate flow measurement in partially filled pipes. TIDALFLUX is designed to measure reliably between 10% and 100% of the pipe cross section. The integrated level sensors in the liner are in no contact with the liquid and are therefore insensitive against fat and oil floating on the surface.

Multi purpose, all-round, ultrasonic flowmeter for liquids in all industrial processes The OPTISONIC 3400 flowmeter is an unique, 3-beam, inline, ultrasonic flowmeter, designed especially for measuring homogeneous conductive and non-conductive liquids, with high accuracy and reproducibility, over a long period of time. This provides extensive self-checking of internal circuits and information regarding the health of the measuring sensor, but just as importantly, vital information about the process and process conditions. Fieldbusses are, HART®7, Foundation Fieldbus, Profibus PA and Modbus, all with NAMUR NE 107. These advanced diagnostic features makes process life comfortable, reliable and accurate over a long period of time.

The ALTOSONIC V12 is a 12-chord ultrasonic custody transfer (CT) flowmeter for natural gas. It has been designed to offer the best possible measurement accuracy, not only during calibration under ideal conditions but also during less ideal conditions in the field. As a result, ALTOSONIC V12 is the first ultrasonic flowmeter that was certified to OIML R137 class 0.5 by NMi. Due to its design with 12 acoustic chords a flow conditioner is no longer required; standards such as AGA9, ISO 17089 and MID are met with just 5D straight inlet piping. CBM flowmeter diagnostics are standard and give an exact picture of what is happening inside the flowmeter. With the optional KROHNE Care diagnostic expert system an integrated web server becomes available that presents the results as an easy to access webpage – in plain language.

Ultrasonic gas flowmeter The OPTISONIC 7300 offers an ultrasonic measurement system dedicated for process gas flow applications. The OPTISONIC 7300 does not have the limitations that are usually associated with traditional gas flow meters like periodical recalibrations, maintenance, pressure loss and a limited flow range. The OPTISONIC 7300 combines the advantages of ultrasonic measurement in a way that it is efficient, reliable and easy to use.

The OPTISONIC 6300 P is a portable, battery-powered ultrasonic clamp-on flowmeter for temporary flow measurement of (non-)conductive liquids. It can be used at virtually any location and without process interruption or need to cut pipes. Due to its flexibility, the meter is equally suited for comparative measurements on stationary measuring equipment (e.g. pumps, flowmeters etc.) or for use as a short-term replacement of faulty devices. The OPTISONIC 6300 P consists of a combination of one or two clamp-on sensors and one handheld electronic signal converter. The robust clamp-on rail can be easily attached to almost any pipe up to DN1500/160". The readings of the meter are shown on the handheld LCD and are stored in the integrated memory for data logging. In addition, all readings can be transferred to a PC via the included USB stick in order to further analyse or store the data.

Small flowmeters (metal) The DK 37 variable area flowmeters can either be equipped with a mechanical or electronic indicator and are suitable for measuring gases and liquids. They are sturdy, versatile all-metal measuring devices. All devices are fitted with a metering valve to accurately set the flow value. PPS housing as standard, stainless steel housing as option.

Sanitary and hygienic solution The OPTIFLUX 6000 electromagnetic flow sensor is specifically designed to stay clean and sterile in compliance with the most stringent demands prevailing in the food & beverages and pharmaceutical industries. There are no crevices, gaps or blind spots and the flow sensor offers full CIP/SIP possibilities. The flow sensor is conform FDA regulations for all wetted materials and is certified in accordance with EHEDG and 3A.

Ultrasonic flowmeter for high temperature gas and steam As the OPTISONIC 8300 provides a large measurement range and does not require recalibration, the installation can be simplified and costs reduced. For example since the flow sensor does not need to be removed, shut off valves and a bypass are not required. Also thanks to the large measurement range, a dual range measurement setup is not required. Traditional steam measurement solutions need continuous attention and recalibration to guarantee proper operation. As the diagnostics of the OPTISONIC 8300 enables it to look after itself, it does not require any attention. Even periodically recalibration is not required since the OPTISONIC 8300 provides excellent long term stability. Periodical verification of the proper functioning of the device can easily be done using the diagnostics as required.

Guided Radar (TDR) Level Meter This device  is a 2-wire TDR level meter for measuring distance, level, volume and mass of liquids and solids. Its simple, compact design allows service technicians to quickly assemble the probe and attach it to a threaded connection. It is an affordable solution for applications that do not require a high level of accuracy and is also an excellent alternative to traditional level controls such as RF Capacitance, conductive and DP transmitters. The display can be ordered with the device or as an accessory. It shows measurement data on a 128 × 64 pixel screen. The configuration menu permits the device to be set up in a small number of intuitive steps.

The all-in-one solution Already the basic version of the OPTISWIRL 4200 is equipped with a temperature compensation for saturated steam applications. With the optional pressure sensor the OPTISWIRL 4200 has an integrated density compensation available, which even allows an exact measurement of gases and superheated steam with varying process conditions. The additional integrated gross and net heat measurement makes the OPTISWIRL 4200 to be a reliable partner for advanced energy management systems. The OPTISWIRL 4200 was designed for the safety-related applications from the very beginning. It was developed according to the standard IEC 61508 edition 2. The certification is effected within the scope of a Full Assessment by TÜV Süd. Thereby the OPTISWIRL 4200 can be used for continuous volume flow measurement in safety-related applications with classification SIL2.
