CENTRIFLOW BWS:
Low Cost Alternative to Impact Flow Meters and Belt Scales
Eastern Instruments is excited to introduce the CentriFlow BWS, an economical, yet extremely accurate gravimetric in-line mass flow meter that positions itself as an alternative to impact flow meters and belt scales. The CentriFlow BWS measures product dynamically, meaning that it measures product while it is moving through your process. The BWS is perfect for measuring granular solids such as grains, pellets, beans, wood chips or even pet food as well as free-flowing granular powders such as sand.
The CentriFlow BWS can accurately measure flows ranging from around 2,000 lb/hr (907 kg/hr) up to 200,000 lb/hr (90,718 kg/hr).

TECHNICAL INFORMATION
Below, you can find the manuals for the CentriFlow BWS family of solids flow meters. The manuals have been divided into the Mechanical Manual for the meter module and the Electronics Manual for the touchscreen interface and setup. There is also a section for troubleshooting and maintenance procedures as well. Feel free to Contact Us with any questions.
The unique gravimetric design of the CentriFlow BWS allows this model of CentriFlow to achieve a +/-(1% - 2%) accuracy full scale on virtually all granular flowable solids.
The CentriFlow Meter is a gravimetric solids flow meter that utilizes a centripetal force based flow measurement technology to maintain an extremely accurate flow measurement.
The CentriFlow Meter is not affected by changes in product elasticity, density or shape. Even changes in flow rate have little impact on the flow measurement accuracy.
The CentriFlow Meter measures product as it slides across our measurement pan, however, due to the patented design of the flow meter, the CentriFlow actually cancels the frictional force components so that friction of the product being measured does not impact the accuracy of the measurement.
The BWS comes with sturdy high-grade Carbon Steel/Stainless Steel flow paths and the Enclosure is made of 3/16" Painted Carbon Steel for structural integrity. The meter can be mounted directly, via the enclosure itself.
With a simplified design that integrates the electronics and meter module, installation is extremely simple. The integrated electronics are mounted directly to the rear of the CentriFlow BWS for easy calibration.
The CentriFlow Meter maintains its accuracy with a maximum 20 to 1 turn-down capability based on volumetric capacity.
CENTRIFLOW BWS APPLICATIONS
The CentriFlow BWS Meter has been used for numerous applications across a variety of industries, especially in industries that measure granular materials such as pellets or grains. Whether the meter is used to optimize the performance of other equipment or to fill railcars and trucks for loadout, the CentriFlow BWS will consistently deliver an accurate flow measurement that you can count on. Please see a sample of the applications that our flow meter has been a part of over the years.

CENTRIFLOW BWS: ECONOMICAL MASS FLOW METER
Often, when considering a measurement system, especially when measuring less expensive products, flow meter cost can be a determining factor in the selection of a flow meter. Unfortunately, extremely accurate flow meters can be very expensive and conversely, meters such as Impact Flow Meters, that can be relatively inexpensive are typically not very accurate at all.
The CentriFlow BWS has redefined this dynamic by empowering customers with a choice that ensures both accuracy and economy. With an accuracy of better than +/- 2.00% on most flowable, granular products, the BWS is much more accurate than many alternative technologies. Maybe even more importantly, however, is that at half the cost of some of the highly accurate models, the CentriFlow BWS is a very economical choice in industrial weighing.
The accuracy of the CentriFlow BWS is a result of Eastern Instruments' patented CentriFlow design which is based on the principle of centripetal force. As product slides through the BWS flow meter, the product slides around a curved measurement pan which exerts a centripetal force on the curved surface. The meter accurately measures the deflection of the measurement pan as this centripetal force is exerted. Rather than impacting the measurement pan like an impact flow meter, product actually slides around the curved surface making it a much more accurate alternative. Use of centripetal force based measurement technology allows the CentriFlow BWS to be a highly accurate and repeatable alternative to impact flow meters, weigh belts and Coriolis style flow meters. The BWS features a simplified design, integrated electronics and a very robust construction, along with a high level of accuracy, all of which is available at a very low cost.
FREE FLOWING MATERIALS
The CentriFlow BWS meter is a bulk solids meter designed specifically for measuring granular bulk solids such as grains and pellets continuously within a process. The BWS is perfect for applications where budget is a primary concern.
The CentriFlow Integral Electronics is an integral electronics package for the CentriFlow BWS style systems which mounts directly to the rear of these style meters. The Integral electronics features a 4" color touchscreen HMI that allows basic functionality including calibration. The main run screen shows a live reading of both flow rate and total. The features and benefits of the electronics include the following:
FEATURES AND BENEFITS
The BWS Electronics are mounted directly to the rear of the BWS in a White painted Carbon Steel Enclosure for easy access and mounting.
The CentriFlow BWS Electronics features a 4 inch color touch screen HMI that makes calibration as easy as pushing a button.
Both the flow rate and the total are displayed simultaneously on the main screen.
The CentriFlow BWS integrated electronics includes a a universal power supply that requires incoming power of between 85 and 264 VAC.
The standard outputs for the BWS Integrated CentriFlow Electronics, are a 4-20 mA signal that is equivalent to flow rate, and a Weighted Count Output that is equivalent to total.
If access to the integral electronics on the rear of the meter is limited, then a optional remote ratemeter totalizer is also available.
