OW-300 SERIES OIL / WATER METERS
Liquid/Liguid Concentration

DESCRIPTION

The AGAR OW-300 Series oil/water meters measure liquid-in-liquid concentrations by measuring the complex permittivity properties of the flow stream using a multiple high frequency method. Typical applications include crude oil and finished product pipeline monitoring, water in slop oil, glycol and water, and aqueous/organic measurement. The OW-300 Series is the third-generation design, liquid/liquid analyzer developed by Agar Corporation. Agar introduced the industry's first 0-100% oil/water meter to the market in 1985.

SYSTEM CONFIGURATION

The OW-300 system consists of a primary probe, the measurement electronics, and a data analysis system (DAS) that can be remotely mounted from the field sensor. The OW-300 probe is offered in a spool-type configuration and insertion-type assembly.

The instruments are calibrated using Windows-based software from a laptop computer. The software is also used for troubleshooting, viewing trends, and retrieving historical data.

The OW-300 Series utilizes a combination of explosion-proof enclosures and intrinsically-safe electronics that provide signal outputs/inputs to the probe. The DAS is also a flow computer that can provide net oil, net water and flow rates when flow meter input is supplied. The data system is transmitted with 4-20mA signals, HART and MODBUS.

Typical Applications

  • Pipeline BS&W measurement for refined products
  • Crude pipelines
  • Desalter crude feed
  • Well testing
  • LACT units
  • Separation control
  • Shipping terminals

OW-301 Series

Sized: 1" to 4"

DESCRIPTION

The AGAR OW-301 is a Spool Piece design available for 1" to 4" flow lines. The sensor should be mounted in a location where the fluid will be well mixed (normal recommendation is vertical flow upwards). The spool piece is available in an "L" or "S" shaped design. In addition, the OW-301 will have a stable performance in common pipelines when the fluid composition changes regularly.

The AGAR OW-300 measures hydrocarbon/water mixtures over the range of 0-40%, water (oil continuous emulsions). The Agar OW-301 accuracy of measurement will not be affected by changing salinity, density, viscosity, and temperature of the components being analyzed.

SYSTEM CONFIGURATION

The OW-301 system consists of an in-line probe, the measurement electronics, and a Data Analysis System (DAS) that can be remotely mounted from the field sensor. The probe is offered in a spool type configuration.

OW-302 Series

Sized: 6" and above

DESCRIPTION

Unlike other microwave, density or capacitance based instruments; Agar's OW series meters are the only devices in which the accuracy of the measurement is not affected by changing salinity, density, viscosity, temperature or velocity of the components being analyzed. The high frequency signal will maintain accuracy in the presence of process coatings that would be detrimental to optical instruments.

The Agar patented "seal-housing" connects to the isolation valve. After installation, the OW-302 probe is inserted through the valve and nozzle into the flow line. Agar's OW-302 monitor features an insertable sensor with a seal housing for installation and retraction while the pipeline is in service and under pressure for flow lines 6" and larger. An insertion tool is available for insertion into high pressure lines. The sensor has a blow-out preventer to ensure that the sensor is not removed from the seal housing without the isolation valve being closed.

SYSTEM CONFIGURATION

The OW-302 system consists of a primary insertion-type probe, the measurement electronics, and a Data Analysis System (DAS) that can be remotely mounted from the field sensor. The probe is offered in an insertion type assembly. The OW-302 probe is mounted perpendicular to the flow in a vertical section with ascending flow at a point where the fluids are well mixed to ensure proper measurement. Common installation requires a 2" full port isolation valve connected directly to the nozzle on the flow line.
