`Truck Loading / Unloading with Micro Motion

`
`Emerson’s Todd Fortman and an engineer with a distributor shared an application story around truck loading and
`unloading. Their abstract:
`
`A Wisconsin based chemical distributor required an accurate and efficient truck loading and unloading
`solution. With over fifty chemicals needing to be loaded into twenty to thirty multi-compartment trucks daily,
`they required a flexible and robust solution. The plant desired a system that would minimize operator error and
`provide a safe solution in a Class I / Division I environment. The solution would need to be able to handle air
`in the system, as a blow down process was required.
`
`They opened their presentation describing some of the challenges with truck loading. Entrained air is a common issue in
`this application. The distributor recently opened a new truck loading facility of chemicals where the source chemicals
`come in via rail.
`
`Key project requirements for bulk loading and unloading were accuracy, reliability, temperature correction, ease of use
`for operators, and improved integration with the site PLCs. Positive Displacement (PD) meters with air eliminators had
`historically been used for load/unload measurement. The measurement devices are located in Class 1 Division 1 areas.
`
`The distributor became aware of Coriolis flow and density measurement technology. They performed extensive testing
`with fluids with entrained air rand from 5-20% void fraction. These tests were much tougher than the application would
`require. The Micro Motion meter technology performed best with an average error across this range of entrained air of
`0.5% versus 5% with other devices tested. This amounts to 5 pounds per thousand pounds instead of 50 pounds.
`
`Meters were preferable to truck scales since the bays were dual-use between trucks and rail cars.
`
`Coriolis technology is fundamentally a mass flow measurement technology. Density is measured by the frequency of
`vibration of the tubes in the meter. The Micro Motion web site has an excellent theory of operation section if you are
`unfamiliar with how this technology works.
`
`24 2-inch Elite Micro Motion meters with enhanced core processors and 1700 transmitters were used in the solution.
`There is a pump at the tank which pumps through the meter to the loading arm. A three-way valve sets where the flow is
`inbound to the tank, or outbound to the railcar or truck. The application was optimized for entrained air which includes a
`vertical flow installation, and elbow and control valve after the meter to add back pressure as required and operating the
`2″ meter in its upper range.
