MATERIAL OF CONSTRUCTION
METER CASING AND ENCLOSURE: While the meter casing is typically constructed out of Aluminum, it can also be constructed from Stainless Steel for corrosive resistance as well as for Food Grade applications. For meters with an enclosure, such as the Type II Meter, the standard material of construction is Stainless Steel, however painted Carbon Steel is also available.
FLOW SURFACES: The flow surfaces of the meter, including the Pan, the Tangential and the Diverter can either be a welded, one-piece assembly for applications such as Food Grade applications, or they can be composite assemblies with interchangeable liners for inexpensive replacement of worn surfaces. A variety of liners and coatings are available for added wear resistance and flow enhancement.
AIR PURGE SYSTEM: The Air Purge System, typically used for dust and moisture control, fills the back casing of the meter with instrument quality air, thereby creating a positive pressure to keep condensation, dust and other matter from interfering with the measurement.
BOOT CLAMPS: Boot clamps seal the Pan Arm Boots ensuring that dust and moisture from the process are unable to enter the rear of the meter, thus causing erroneous readings or possible damage to the loadcell of the meter.
LINERS AND COATINGS: A variety of coatings as well as flow surface materials can be utilized in order to improve the flow of products across the Measurement Pan and other flow surfaces. In addition, a Curved Corner Pan is available for powdery products that could collect in the corners of a standard Pan.
PULSED AIR SYSTEM: The Pulsed Air System was designed to deliver a pulsed blast of dry, instrument air to the area both above and below the Measurement Pan in a manner that will clear product and debris from the Pan's surfaces without adversely affecting flow measurement readings. Use of the Pulsed Air System is intended to both assist product flow as well as to eliminate product built up on the Pan, which, if left unchecked, could result in less accurate flow measurement.
INTEGRATED AIR ENTRAINMENT: The Integrated Air Entrainment System was designed to deliver a continuous stream of air to the CentriFlow Meter's Measurement Pan. Its continuous flow of dry air reduces build up and assists in the flow of product on the measurement surfaces without affecting measurement readings as well.
VIBRAWEIGH: The VibraWeigh option, typically used in powder applications, keeps small particle size materials (down to 10-50 microns) from building up on the Pan surfaces. The VibraWeigh works by gently vibrating the Measurement Pan from side to side in a manner that keeps product flowing across the Measurement Pan without building up, while at the same time, not affecting the measurement accuracy of the meter.
INTRINSIC SAFETY BARRIERS: Intrinsic Safety Barriers are used when the CentriFlow Meter will be installed within a hazardous area and the CentriFlow electronics will be located within a non-hazardous area in order to isolate the CentriFlow Meter from its electronics.
EXPLOSION PROOF SYSTEM (CLASS II DIV 2): This explosion proof system is used for installing the CentriFlow Meter and its electronics within a Class II Div 2 rated area and includes a pressurization or purging system that prevents the entrance of combustible dust into the meter or its electronics.
EXPLOSION PROOF SYSTEM (CLASS I DIV 2): This explosion system is used for installing the CentriFlow Meter and electronics within a Class I Div 2 rated area. This option prevents the entrance of flammable gas or vapor from accumulating within the meter or its electronics by performing a series of four air exchanges and then, applying a positive pressure to the system.
