The DK37 M8 is a variable area (VA) flowmeter with electrical signal output and bargraph indication or mechanical indicator with two optional limit switches. The versatile all-metal measuring device is suitable for flow measurement of gases and liquids. Due to its sturdy design, the VA meter can be used at temperatures up to +200°C / +392°F or pressures up to 220 barg / 3190 psig. It is fitted with a needle valve as standard to accurately set the flow value. The DK37 M8 comes with vertical or horizontal process connections for NPT or G thread, flange adapters and many other connection options. To provide constant flow rates in case of variable inlet or outlet pressures, the VA meter is also available with flow regulators. It has approvals for hazardous areas and is suitable for use in Safety Instrumented Systems (SIS).

The OPTIMASS 2000 is a Coriolis mass flow sensor. Combined with the MFC 400 signal converter it forms the OPTIMASS 2400 high-performance Coriolis mass flowmeter for bulk mass and high volume flow measurement of gases and (non-)conductive liquids.

The OPTISONIC 7300 is a universal 2-path ultrasonic gas flowmeter for process and utility gas measurements in oil and gas refineries or the chemical or petrochemical industries. It is also suitable for non-custody transfer natural gas applications or applications with (compressed) air, mixed or flue gases (up to +180°C / +356°F). Using the transit time differential measuring principle, the OPTISONIC 7300 delivers high performance over a wide flow range (up to DN600 / 24", turndown ratio: 100:1). The measured volume flow can always be calculated to standard conditions using the input of temperature and pressure sensors, which can be directly connected to the device. Following the initial calibration, the device provides accurate measuring results (±1% error of measured value). The OPTISONIC 7300 does not have the limitations associated with turbine or other traditional gas flowmeters like periodical recalibrations, maintenance, pressure loss and a limited flow range.

The DK32/34 is a variable area (VA) flowmeter for measuring low flow rates of liquids and gases. The tried and tested meter is particularly suitable for flow monitoring and dosing in gas analyser systems or on purge panels. Due to its robust all-metal design it can also be used in difficult process conditions with temperatures up to +200°C / +392°F or pressures up to 400 barg / 5800 psig. It is available with a metering valve as standard to accurately set the flow value. The DK32/34 operates without auxiliary power supply. The device just features a local indication with two optional MIN/MAX limit switches (NAMUR) or a reed contact. To provide constant flow rates in case of variable inlet or outlet pressures, the VA meter is also available with flow regulators. It comes with horizontal or vertical process connections for NPT or G thread and many other connection options. The VA meter has various approvals for hazardous areas.

The OPTIMASS 6000 is a Coriolis mass flow sensor. Combined with the MFC 400 signal converter it forms the OPTIMASS 6400 high performance Coriolis mass flowmeter for all process applications including cryogenic or high temperature media as well as high pressure fluids.

Flowmeters especially for gases The VA 45 variable area flowmeters were designed to measure gases. They can be used, for example, in industrial ovens, forges and furnaces, and protective gas and heating systems. The standardized device design is available with various connections that conform to standards. The glass measuring cone, protected by a metal sleeve with a viewing glass, makes it easy to read the flow directly.

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.

WITT offers high-quality gas mixers / gas blenders and gas metering systems for two or more gases, for high flow rates and highly fluctuating gas withdrawals. You can choose between various options: According to your requirements, WITT gas mixers / gas blenders are available for nearly all technical gases and flow rates: for the optimal gas mixture for welding applications, the required gas concentration for food packages (modified atmosphere packaging = MAP) or the production of synthetic air for medical applications. State-of the art mechanical or electronic gas mixing systems provide accuracy and process safety. You can also control your gas mixing systems conveniently via Intranet, Internet or mobile devices. Combinations of WITT gas mixers / gas blenders with other WITT quality products such as gas analysers are also possible. They can be manufactured as complete system solutions.

The installation system consists of high-quality NiroSan® Gas press fittings with yellow moulded sealing rings made of HNBR (hydrogenated nitrile butadiene rubber) and NiroSan® stainless steel system pipes according to EN 10312, DVGW-Arbeitsblatt GW 541 and EN 10312. All NiroSan® Gas press fittings are made of the material 1.4404 / AISI 316L (for moulded fittings) and 1.4408 (for threaded fittings and stainless steel precision castings). The material contains at a minimum of 2.3 % molybdenum and a lower carbon content than the conventional steel quality 316. Thereby these materials are not only of equal value but in addition, material 1.4404 / 316L stands out on account of its considerably higher corrosion resistance. The NiroSan® Gas press system is certified in accordance with and all important European certification bodies.

The use of protective gases is an essential element of precise quality control (HACCP) in food packages (Modified Atmosphere Packaging = MAP). MAP gas mixers by WITT provide controlled gas quality and safety in your packaging process – for germfree and preserving food.
