viscosity or flow rate sampling Consistometer Let it flow! The Consistometer is a low cost, durable, instrument for accurately checking laboratory or production samples against consistency, viscosity or flow rate standards. This instrument is used to determine the consistency of viscous materials by measuring the distance that the material flows under its own weight in a given time interval. The instrument allows producers of such viscous products as jellies, preserves, sauces, etc to predetermine formulas for their product and to standardize production lots. It uses little bench space yet is probably the simplest, most accurate method of conducting a variety of flow associated tests. It is already widely used in the chemical, paint, cosmetic and food processing industries. It provides a single parameter for a variety of flow tests which can be carried out over any period under as near identical conditions as possible. The Consistometer or Bostwick Consistometer is manufactured from stainless steel engraved with a series of precise graduations at 0.5 cm intervals. To ensure accurate reproducibility the instrument is levelled using the adjustment screws and spirit level. METHOD OF USE: 1. A measured sample, usually 75 ml, is placed in the reservoir behind the gate. 2. The gate is released, by pressing the lock release lever - the spring action ensures it opens instantaneously. 3. As the fluid flows down the instrument its progress can be accurately measured using the graduated scale. By comparing the flow rate to specified time periods the physical properties of the sample can be calculated.

It is important to know that not every textile filter can be washed and that the filtration performance will deteriorate over time through washing, similar to the way your clothes are affected by the washing process. How quickly that degradation will happen and how much this will affect the filtration performance does depend on type of polymer and fabric and the processing conditions. Getting reliable advice from the filter manufacturer and following these instructions carefully will give you a long lasting and well performing textile filter. DRM has been manufacturing textile filters since 1970 and has acquired a wealth of knowledge regarding the washing of technical textiles and the consequences this may have on their performance.

With the operation taking place in a hazardous area, the need to control all types of ignition sources is absolutely paramount however the vacuum transfer process can generate large amounts of static electricity, requiring confirmation of proper bonding to a verified grounding point. The new truck mounted Earth-Rite® MGV derives its power source from the vehicle battery, and uses certified Intrinsically Safe monitoring techniques to not only indicate a good bond to a static grounding point, but more importantly verification that the ground point to which it is attached represents a satisfactorily low resistance to true earth. Units have obtained Intrinsically Safe certification for use in the Global Petrochemical Industries, according to the requirements of IECEX, ATEX, CSA/ US and NEPSI (China), and may be used in all common gas, vapour or dust explosive environments. To learn more about the Earth-Rite MGV or the dangers of static electricity in hazardous areas please contact Newson Gale. www.newson-gale.com For more information contact Newson Gale Ltd, Colwick, Nottingham Tel: 0115 940 7500 Fax: 0115 940 7501 E-mail: groundit@newson-gale.co.uk Web: www.newson-gale.com 36 Process Industry Informe r October-November 2013
