VistaFlo™ Electronic Flow Measurement (EFM) Solution Hardware

VistaFlo hardware products include SP series programmable logic controllers (PLCs), SS 4203 gas flow computer (GFC), SS 4102 Modbus® multivariable transmitter and the Vision™ series of panel mounted keypad/displays.

• SP32 series PLCs are high performance ten-run flow computers used wherever wells are either close together, or where many runs are measured together such as at headers, gas plants, transmission stations or coal bed methane pods. The PLCs are the processor-onlyversion and are suited for locations where local PLC control of input/output (I/O) is not required. With Ethernet capability, the PLCs are ideal candidates for LAN applications and are currently installed in several production fields that use wireless Ethernet.
• SP350 series are well-rounded PLCs with the same on board I/O complement as the bigger SP32 series PLCs. The PLCs accommodate two- or four-run custody transfer options and have the same expansion capability as SP32 series PLCs.
• SP P series PLCs are flexible controllers complete with integrated power supply, analog and digital I/O and serial communications. As the flagship of Weatherford’s SP series of PLCs, these controllers offer flexible options for those applications that require a mix of analog and digital I/O coupled with multiple communication ports.
• The SPLP model PLC is a low power controller complete with integrated power supply, analog and digital I/O, serial communications and turbine flow meter counter inputs. The controller is ideal for applications that require low power along with a mix of analog and digital I/O and multiple communication ports.
• The SP100 PLC is a cost-effective, one-run flow computer that is ideally suited for EFM applications requiring small amounts of I/O while maintaining custody transfer gas measurement data.
• The SS 4203 GFC is a highly integrated gas flow computer that incorporates a multivariable sensor and a complete PLC. The GFC runs in all SP series controllers. It can be used in a wide range of process control applications including: well optimization, pressure control, odorant injection and more. Coupled with a second multivariable transmitter, the GFC can be used as a two-run gas flow computer.
• Weatherford’s SS 4102 multivariable transmitter offers precise measurements of temperature and process and differential pressures. As a fully digital transmitter, the product offers a built-in choice of Modbus® protocol over serial and/or Ethernet communications along with an optional proportional-integral-derivative (PID) controller and analog output. With this choice, the unit can be used in a wide variety of installations including low power transmitters in remote locations or as an addressed device offering control and measurement in an extended Ethernet network.
• For at-the-well readout and control, Weatherford offers two versions of its Vision keypad/displays.
  • The Vision 10 unit displays two lines of 16 characters each. It has six programmable function keys and two programmable LED indicators.
  • The Vision 50 unit has all the same features as the Vision 10 model, however it displays four lines of 20 characters each, has 20 programmable function keys and 8 programmable LED indicators. In addition, there are 32 alarms available on this unit.
