Flow Computers - Pipeline Measurement and Custody Transfer

Willowglen's Flow Computers have been a leading industry technology for many years. Developed in conjunction with top corporate pipeline operators, our systems have provided the efficient and reliable information needed to effectively run their business.

Unisen™ Flow Computer 5.x

Available in different sizes to accommodate up to 25 flow meters. Willowglen's Unisen flow computer outperforms the competition. It is flexible enough to deal with different configurations of headers and meters. For example, five headers of five meters each, or a mix of seven headers where some runs have two meters, others with eight meters, or whatever your demands require. Willowglen's Unisen flow computer is the best choice. ... MORE

Willowglen can meet all of your needs by providing: Redundant Remote and Master Stations, Comprehensive System Security, Communication Statistics, Operational and Historical Archiving, Compressor Station Control, Sampling, Automatic Pump-off Control, PID Closed Loop Control, and an Optional Integrated Pipeline Simulator.

For Liquids Pipelines, Willowglen can provide the following: Injection of Drag Reducing Agents, Remote Meter Proving, Historical Meter Prover Values, Similar-Day Load Forecasting, Linear Optimization of Regulator Setpoints, Corrected API Liquid Flow Rate and Accumulation Calculations, Net Oil Computation-Capacitance Probe, Optional Integrated Batch Tracking and/or Leak Detection, and an Optional Integrated Pipeline Simulator.

For Gas Pipelines, Willowglen can provide the following: AGA-3 Gas Orifice Flow Rate and Accumulation Calculations, AGA-7 Gas Turbine Flow Rate and Accumulation Calculations, AGA-8 Supercompressibility Correction, NX-19 Supercompressibility Correction, Redlich-Kwong Supercompressibility Correction, and Gas Flow Control.

 

Unisen™ Remote Terminal Units (RTU)

The Unisen™ RTUs can be scaled from a few points up to 2000 points in a single RTU. The RTUs can run in a fully redundant configuration, including supporting redundant I/O cards, ensuring that neither failures nor maintenance will interrupt operation. The intelligence card and firmware are common to all models ensuring Unisen’s rich feature set is available for all sizes of RTUs.

Maintaining the RTUs can be done using a secure embedded web interface allowing configuration from any standard web browser. The RTU import/export capability means that configuration can also be done using standard spreadsheets or by wizards that walk the user through the configuration process. Printers can be directly connected to the RTU for printing of batch reports, configuration data and output from customer specific applications.

Customers using Willowglen’s previous SCANTRACK™ family of RTUs will particularly enjoy the ease of upgrading to the new Unisen family. Upgrading is done by sliding out a card and putting another one in. There is no wiring change, no I/O change and no cabinet change.

The Unisen RTUs continue Willowglen’s tradition of high-reliability, minimal maintenance, and long service life.
