Smith Meter microLoad

1 SPECIFICATIONS. Smith Meter . Bulletin SS06045 Issue/Rev. (7/17). Electronic Preset Delivery System The Smith Meter is a microprocessor based instrument with Ethernet capability. It is designed to monitor and control single product, straight loading. The unit can operate either as a stand-alone instrument or be part of system where it communicates with an automation or SCADA system. FEATURES. One arm, single product loading and unloading Standalone or remote controlled operation LACT control - BS&W monitoring, Sampler, Diverter Ethernet and serial communications Modbus and Smith communication protocols User authorization database and optional card reader Event, transaction and W&M audit logging User configurable load ticket and display Automatic volume correction of refined/crude liquids from LPG to asphalt based on temperature, pressure and density using API MPMS CH.

2 Tables and all industry standard calculations Applications TechnipFMC Promass Coriolis Meter The microLoad is ideal for any liquid transfer application communications for density and status requiring accurate weights and measures approved Globally W&M and electrical safety approved measurement and precise real-time control.

Programmable pulse output Refined products Batch loading/unloading of alcohol, Fully programmable flow profile gasoline, lube oils, fuel oils, solvents, fertilizers, LPGs, Optional display back-up per OIML LNGs, and liquid chemicals into trucks, rail cars and barges. Three levels of parameter access security Ideal for bulk plants, shipping docks, processing installations, and tank farms where a single unblended product is Automated proving assistance transferred.

3 Boolean/Algebraic custom logic expressions Crude Oil The microLoad supports loading, unloading Additization of metered or unmetered products and LACT transfers of crude oil with built-in facilities to MicroMate configuration utility included monitor and average BS&W, control a sampler with up to Programmable language / messages four sample cans, and full diverter valve control. Refer to Continuous monitoring of critical functions publication AB06100 for additional information regarding Pulse security level B upstream/crude oil applications. Temperature Compensation Additive monitoring provides the capability for the The temperature compensation feature provides the to monitor feedback from the piston injectors customer with the ability to compensate for variance in of the additive products. The monitors the temperature from a reference temperature.

The will totalize additive correction factor of ASTM-D-1250-04, and API MPMS volume based on confirmation signals and a programmable CH - 2004 tables as noted below, over the fluid volume per cycle. The totalized volume will print on the temperature range of -58 F to 302 F (-50 C to 150 C). emulated load ticket printed on the printer output. The following API tables can be programmed in the For Smart additives, the firmware has also been designed : 5A, 5B, 5D, 6, 6A, 6B, 6C, 6D, 23, 23A, with a Master/Slave type of communications, with the 23B, 23D, 23E, 24, 24A, 24B, 24D, 24E, 53, 53A, 53B, being the master and the Additive Injector 53D, 53E, 54, 54A, 54B, 54C, 54D, 54E, 59A, 59B, 59D, System being the slave.

Density Correction Additization of Unmetered Products The density correction feature provides the customer The has a feature that allows it to additize with the ability to correct the volume of product delivered products that do not have a Meter providing pulses on the at varying densities (crude). The microLoad can read main product stream. This feature was added to provide a the line density as a 4-20 mA analog signal or through device to handle the injection of lubricity additive into low communications when using a Promass Coriolis Meter .
