    Monitoring solutions for the flow monitoring areas

    Many large combustion plants are now required to monitor mass emissions of major pollutants and to do so requires an accurate measurement of stack gas velocity. The VCEM 5100 is certified to EN 15267 part 3 QAL 1 for all industrial processes including waste incineration. It has several key advantages, firstly the sensors optics are not in contact with the hot and dusty environment, the VCEM 5100 can monitor gases at temperatures exceeding 10000C and the analyser requires minimal maintenance. The VCEM 5100 can be used in extremely dust environments such as SCR’s when dust loadings exceed 10g/m3. The VCEM 5100 is in full compliance with EN/ISO 16911 part 2.

    Compressed air measurement & control flow solutions

    Compressed air isn`t free, so more and more companies carefully monitor its usage. Thermal flow meters are ideal for this application. Because our thermal flow meters measure mass flow directly, no temperature or pressure compensation is required. Thermal flow meters also have a very high turndown, allowing the same flow meter to measure very low leak rates as well as full operational flows.

    Industrial solutions for the leak tester

    A number of industries such as automotive parts (e.g. engine blocks, air bags, etc.), medical equipment (e.g. catheters) and food packaging rely on various verification tests to ensure that such critical parts are leak proof. Industrial leak testing benefits from high speed and excellent repeatability offered by the Axetris mass flow meters. Axetris leak tester customers call it “fast repeatability”.

  • Capabilities of the Adsorbent Tube Injector System (ATIS™)

    The Adsorbent Tube Injector System (ATIS) was developed at Supelco® by R&D Scientists, as a tool to assist in our comprehensive adsorbent research for thermal desorption tubes. The ATIS provides an efficient means of transferring calibration standards in either the gas or liquid phase onto the adsorbent packed tubes. The ATIS employs the technique of flash vaporization to vaporize the sample in a continuous flow of inert gas; the inert gas carries the sample to the tube. The sample pathway of the ATIS is constructed of glass and stainless steel. The calibration standard is injected by a syringe through a replaceable septum in the center of the injection glassware, which is heated. After enough time has elapsed, typically less than five minutes, the tube is removed from the ATIS and analyzed using the appropriate analytical technique for that adsorbent tube.

  • Force Main Systems Sulfide Odor Control with Hydrogen Peroxide

    Force main systems are typically high sulfide odor generators due to septicity conditions related to full pipe flow and a greater anaerobic slime layer (biofilm) thickness. Primary factors that influence sulfide loading generation in a force main include sewage temperature, BOD, retention time, pipe size and flow. Gaseous hydrogen sulfide (H2S) release at the force main discharge is usually the main concern related to odor and corrosion control needs; however, corrosion problems within the pipe can be of a concern (e.g. "crown cutting") at locations where air pockets can lead to concentrated H2S gas build up. Some basic considerations for assessing an appropriate sulfide odor treatment method for force main systems include: Retention time / duration of control Pump station type / cycling (e.g. vfd; start/stop, etc). Force main injection tap points, if any (e.g. air relief valves) Existence of intermediate re-lift stations or in series pump stations Manifold force main systems

  • Smoke generator device for building envelope, energy studies & air tightness testing

    The air tightness or leakage rate of a building is the uncontrolled flow of air through holes, gaps and cracks in the fabric of a building, which may not be detectable simply by looking at the outside of the building. Filling a building or void with smoke and pressurising that volume, will result in a visible discharge of smoke from any problem areas. Smoke is the perfect medium for discovering where leaks are and how big they are! Filling a `leaky` building, ductwork, pipes, aircraft or containment area with smoke and ideally adding a small amount of pressure to the area being tested, will result in a visible discharge of smoke and, simply put, the greater the volume of smoke, the bigger the leak.

  • Secundary air flow measurement for power generation industry

    Secondary Air Flow Overview: The need for accurate, repeatable & reliable combustion air measurements in power generation plants is critical to efficient operation and safety throughout the entire facility and processes. Accurate secondary air flow measurement to the burners is critical for maintaining the proper air to fuel ratio, result­ing in more complete and stable combustion, better performance and lower emissions. Coal-fired power plant applications pose a number of challenges to obtaining these critical flow measurements including large ducts, limited metering runs, poor velocity and temperature profiles, vibration and high temperatures.
