Liquid And Gas Flow Measurement Training Classes

Flow Dynamics will conduct liquid and gas flow measurement training classes during April 2010 at its facility in Scottsdale, Arizona. The classes are intended for managers, engineers, technicians and QA/QC personnel seeking a greater understanding of basic flow measurement principles and application considerations. A three-day liquid flow measurement training class will be offered on 14-16 April and a three-day gas flow measurement training class will be held on 19-21 April.

These courses were prepared with the job requirements of system design and production personnel in mind and offer practical, hands-on instruction in a range of flow-related disciplines. Students attending a Flow Dynamics training course will learn how to apply the latest flowmeter designs in industrial applications. Classes include an overview of flowmeter selection, with advantages and disadvantages of each technology, as well as guidelines for meter usage. In particular, attendees at the liquid course will gain an understanding of density and viscosity effects on flowmeter performance.

Those participating in the gas course will learn about Gas Law calculations and how they apply to gas flow measurements. The course curriculum also includes an in-depth discussion of the methods and equipment necessary for precision primary and secondary standard flowmeter calibration. Flow Dynamics provides calibrations for all Cox Instruments turbine flowmeters.

Particle-Into-Liquid Sampler Assesses Air Quality

The Particle-Into-Liquid Sampler (Pils) from Metrohm UK is said to be an effective way of producing real-time measurements for assessing air quality. The Pils system can measure particulate pollutants several times an hour and when used in combination with a Metrohm ion chromatography system, inorganic ions such as ammonium, nitrate, sulphate and chloride can be detected and quantified with a cycle time between five and 20 minutes depending upon application.

The Pils system uses small quantities of steam to form water droplets on individual aerosol particles. The water droplets containing the dissolved aerosols can then be captured and analysed by ion chromatography. The instrument can be operated unattended for up to 20 days depending upon the volume of reagents and size of denuder and can take samples every five minutes. The current method used for analysing airborne particulates is filter sampling.

The filters collect the aerosol particles usually over a 24-hour period and the results are reported as daily averages. High time resolution means more information can be gathered and trends and cycles can be observed. Applications where the Pils system can be used include indoor air quality monitoring, ambient air quality monitoring, tunnel monitoring, waste transfer and landfill site monitoring, stack emissions monitoring, and emission protection for employees.

Metrohm UK offers a direct online on-site analysis using well-established techniques and no manual sample preparation is needed. In combination with an ion chromatograph it is possible to determine the following species: cations (Na+, NH4+, K+, Ca++, Mg++), anions (Cl-, NO3-, NO2-, SO4--), organic acids (acetate, formate, oxalate), LOD (depending on ion) from 5-100 ng/m3. Full installation and training by a Metrohm applications chemist is included in the price of the system.

Gizmo Unveils Liquid-Level Alarm For Tanks

Gizmo Engineering has introduced its first intrinsically safe liquid-level alarm for tanks. The battery-powered alarm is also said to work well in drums or IBC tote tanks. The company claims that it can run for years from battery power as there is zero-power drain when the unit is not alarming.

The loud pulsing alarm is intended to cut through loud industrial noise. Additionally, a push-button feature is available to silence the alarm. It is said to be easy to install because it comes in any necessary mounting, including many sizes of threaded plugs, bolt-on flanges, a flat plate or bulkhead feedthrough.

The unit is built from the ground up for wet, corrosive environments and rough handling. The float switch is protected from physical abuse inside a pipe and is further protected from debris by a screen.
