EASTERN INSTRUMENTS SOLIDS HANDLING SOLUTIONS Precision Material Handling Equipment

Eastern Instruments Material Handling Solutions Solids Flow Meters About Eastern Instruments Eastern Instruments, a Certified Women’s Business Enterprise, is an engineered solutions company located adjacent to the North Carolina International State Port in Wilmington, North Carolina. Since 1984, we have been engaged in the design and manufacture of devices that measure and control the flow of industrial bulk solids. These devices have been integrated into a variety of systems for regulating operations and improving efficiency across nearly every industrial sector. Every device within Eastern...

The Principle of Centripetal Force and the Science Behind our Material Handling Equipment Why are the solids flow measurement and control devices from Eastern Instruments so accurate? The secret lies in their zero-friction patented design, which is based on the principle of centripetal force. Centripetal force is the inward force required to keep an object moving in a circular path. It can be shown that an object moving in a circular path has acceleration towards the center of the circle along a radius. This radial acceleration, called the centripetal acceleration, is such that if an object has...

Solids Flow Meters The CentriFlow® Meter Different Types of CentriFlow® Meters The CentriFlow® Meter is the centerpiece of our flow measurement devices and has been a proven leader in solids mass flow measurement for over two decades. Perfect for nearly any industry where accurate and dependable mass flow measurement is required, the CentriFlow® Meter comes in a variety of styles and models to accommodate virtually any product ranging from smaller particles such as powders and feed pellets to bulky materials such as potato chips or whole crushed plastic bottles. No matter the application, there...

EASTERN INSTRUMENTS Why choose the CentriFlow®? Accuracy Plant Efficient Configurations Unlike existing technologies that calculate mass flow by making assumptions based on weight, speed, belt tension, or volume, the CentriFlow® Meter actually measures flowable solids in a process. This unique measurement ability allows the CentriFlow® Meter to have a typical ±0.25% accuracy full scale on virtually all flowable solids, significantly improving the industry standard. Designed to fit into nearly any existing process, the CentriFlow® Meter is available in multiple configurations that minimize the...

Type I Meter CentriFlow®: Type I Models The CentriFlow® Type I Meter is a solids mass flow meter designed to measure bulk solids continuously in a process and is specially designed to be installed directly after feed devices that move material in a horizontal direction such as belts or vibratory conveyors. Perfect for installation in both new construction or retrofitted into existing processes, the CentriFlow® Type I Meter has a minimal vertical footprint that can be installed within as little as 20” of height. With a wide variety of options for flow surfaces, the Type I meter can be optimized...

EASTERN INSTRUMENTS CentriFlow®: Type I Installations Type I - In Line Flow Type I - Reverse Flow There are two ways to install the CentriFlow® Type I Meter, in the Reverse Flow orientation and in the In Line Flow orientation. An In Line Flow installation allows product travelling in a particular direction to continue travelling in that direction, even as it exits the CentriFlow® Meter. This type of installation ensures the least amount of damage to delicate products as the product flow slides continually through the meter without ever impacting or colliding with any meter flow surfaces. This...

Type II Meter CentriFlow®: Type II Models The CentriFlow® Type II Meter is a solids mass flow meter designed to measure bulk solids continuously in a process and is specially designed to be installed directly after feed devices that move material in a vertical direction such as rotary valves, screw conveyors, bucket elevators, etc. Perfect for installation in both new construction, or retrofitted into existing processes, the CentriFlow® Type II Meter has a small, vertical footprint as compared to other metering devices on the market (with a vertical footprint of only 36" in height for the Standard...

EASTERN INSTRUMENTS CentriFlow®: Type II Installations SLIDE GATE: Slide gates create a very consistent feed of product for the CentriFlow® Type II Meter and allow for very accurate measurement. If you require both flow measurement and control of your product, the CentriFeeder® with ICV combines a CentriFlow® Meter with an Integrated Control Gate for very accurate measurement and control of granular products. See our Feeder catalog for more information. The CentriFlow® Meter is typically installed directly after a feed device in order to ensure a consistent flow of product through your meter....

Solids Feeders The CentriFeeder® CentriFeeder® Models The CentriFeeder® is the name given to Eastern Instruments' solids feeder line of products. These devices utilize the principal of Centripetal Force to measure the mass flow of product that passes through the feeder meter, but then goes a step further in order to control the flow of product using the mass flow signal. These devices come in a variety of styles and configurations. No matter the type of CentriFeeder® the unit will provide two standard outputs: a 4-20 mA signal proportional to flow and a totalizing pulse output. Additional available...

EASTERN INSTRUMENTS Integral Control Valve The accuracy of the CentriFeeder® with ICV begins with the feeder's Mass Flow Measurement. The instantaneous flow measurement is used to create a PID control loop that controls the Integral Control Valve (Controllable Slide Gate) which modulates in order to control the product's flow for either batching or continuous blending applications. The feeder's unique measurement ability and quick response PID control loop ensures that the CentriFeeder® with ICV has a typical accuracy of ±0.50% of reading on virtually all granular solids. Measurement Pan Great...
