The Type I Configuration is designed for horizontal feed systems and can be mounted keeping the product stream flowing in-line or reversing the direction of flow. This configuration, in its in-line form, is ideal for products such as confectionaries, snack foods, wood products, and much more. Typical Feed Systems include belt conveyors and vibratory conveyors.

The Type II Configuration is designed for vertical feed systems and can be mounted keeping the product stream vertically in-line. The configuration utilizes an enclosure, which includes a diverter plate that directs product towards the Measurement Pan and allows it to discharge below. An optional flange is available on the intake to mate to a transition or flexible connection. The enclosure also incorporates an access panel to view internal product flow and an integrated calibration chute door for the purpose of product collection to calibrate the meter. This configuration is ideal for processes that are highly pulsating due to the feed system and/or products that need to be contained or enclosed. Typical Feed Systems include screw conveyors, rotary valves, and slide gates.

The CentriFlow^® Low Density Meter is a specialized version of the CentriFlow^® Meter and is designed to measure low-density materials. The radius of the Measurement Pan is twice that of the Standard CentriFlow^® Meter. By enlarging the Measurement Pan radius, the low density/high bulk, large particle materials are accommodated. Materials such as tobacco, (whole leaf, strip, stems, processed leaf, etc.), wood chips, leafy vegetables, and many others can be measured accurately using the Low Density Meter. It is available in multiple sizes and can be fed from most feeding devices.

The Measurement Pan of the CentriFlow^® Meter is the curved section where the material flow rate is measured. The material slides centripetally through this section during the process flow. In order to allow for different applications and process products and to also accommodate for wear, the Measurement Pan incorporates liners, which easily bolt on and off. This allows the CentriFlow^® Meter to be maintained simply by changing out liners instead of full assemblies. There are different liners depending on the application. There is also the option to have an All-Welded Stainless Steel Pan, which is used in applications that require sanitary contact surfaces.

The tangential section of the CentriFlow^® Meter brings the process material into the Measurement Pan with tangential entry for centripetal measurement. This reduces wear on the Pan Liner and ensures the proper presentation to the Measurement Pan to obtain the best accuracy. Tangential Liners can be used and are bolt on surfaces that are selected specifically for different applications and process products. Typically, these are matched to the same material chosen for the Pan Liner. One-Piece Tangential Plates are available for Food-Grade Applications. Some Tangential Entries can be extended in height for applications with bulk density and large particle size. For bouncy and/or elastic process materials, the Tangential Guide Cover Plate keeps them contained within a “throat” area to ensure proper presentation to the Measurement Pan.

This allows for a local rate or total display and optional averaging analog flow signal.

Corrosive Resistant/Wash Down Remote Electronics Package with EMI/RFI View Windows

For applications such as food processing, chemical industry, and pulp and paper processing where equipment is subject to corrosive wash down, or direct spray, typically a NEMA-4X enclosure is utilized. When the environment also contains electromagnetic interference or radio frequency interference, an enclosure will need to protect the electronics from this interference. This option can be used to address both these environmental issues. It is constructed of 304 Stainless Steel and has all components integrated into the enclosure thus keeping the enclosure face clear of protruding devices.

CentriView™ Remote Electronics Package

For applications, such as food processing, chemical industry, and pulp and paper processing, the CentriView™ Electronics System is used with the CentriFlow^® Meter to view process parameters and control common process functions such as batching and flow control both a separate functions as well as batching and flow control combinations. System choices range from samll painted steel enclosures with rate and total readouts to corrosive resistant EMI/RFI shielded enclosures with color touchscreen HMI's controlling batching and flow control functions.

Explosion Proof System #1

The Explosion Proof System #1 is a pressurization or purging system that is used when the CentriFlow^® Meter and its electronics are required to be in a Class II, Division 2 area. This unit prevents the entrance of combustible dust into the CentriFlow^® Meter and its electronics, by manually removing any dust and then applying a protective gas supply to maintain a “safe” pressure of 1 inch of water. Power can then be applied to the protected equipment under conditions established by the Division Rating. This unit can be mounted nearby the CentriFlow^® Meter Electronics, tubed to the electronics enclosure and casing of meter and then referenced from either the enclosure or casing of meter.

Explosion Proof System #2

The Explosion Proof System #2 is a purging system that is used when the CentriFlow^® Meter and its electronics are required to be in a Class I, Division 2 area. The unit prevents the entrance of flammable gas or vapor to accumulate within the CentriFlow^® Meter and its electronics, by performing four air exchanges and then applying a positive pressure to maintain a “safe” pressure of 0.25 inches of water. Power can then be applied to the protected equipment under conditions established by the Division Rating. This unit can be mounted nearby the CentriFlow^® Meter Electronics, tubed to the electronics enclosure and casing of meter and then referenced from either the enclosure or casing of meter.

Air Purge System

The Air Purge System fills the back casing of the meter with instrument quality air, thereby creating positive pressure, to keep condensation, dust, and other matter form interfering with the measurement transducer.

High Temperature Option

The High Temperature Option should be used when process material exceeds 120° F. The air assists in keeping the casing internal temperature down and also utilizes a Stainless Steel Barrier with High Temperature Foam.

VibraWeigh^®

The VibraWeigh^® option keeps small particle size materials down to 10 to 50 microns from building up on the pan surface. This is important in order to keep the process product flowing through the meter and sliding on the Pan Liner. Build up that might divert or impede the flow could result in inaccurate measurement.

Integrated Air Entrainment System (IAE)

The Integrated Air Entrainment System was designed to deliver an even stream of air to the CentriFlow^® Meter’s Measurement Pan. Its continuous, dry air reduces build up and assists in the flow of product on the measurement surface without affecting the measurement readings.

Curved Tangential Feeder (CTF/BTF)

The CentriFlow^® CTF and BTF Transition is ideal for product that is fed horizontally on a belt or vibratory conveyor as in a Type I Configuration. It facilitates the flow through the meter creating a tangential entry into the measurement pan, which increases accuracy and eliminates product breakage. It is a bolt-on accessory to the meter and takes up minimal vertical height. The CTF comes in two curvature radii and can have either low or high sides. The BTF comes in one radii and can have high or low sides. It can be made in a wide array of materials and be finished to optimize wear, minimize product residue, and meet sanitary specifications.
