Liquid/Liquid Concentration

|
Agar's OW-200 series is a second-generation design, microwave based liquid/liquid analyzer developed by Agar Corporation after introducing the first 0-100% oil/water meter to the market in 1985.
The OW-200 Series oil/water meters, consisting of the OW-201 and the OW-202 meters, utilize a microwave transmitter (2.45 Gigahertz) to measure bulk dielectric properties of the flow stream. They measure hydrocarbon/water mixtures over the full range of 0-100%, regardless of the continuous phase. Unlike other microwave, density or capacitance-based instruments; Agar’s oil/water meters are the only devices in which the accuracy of the measurement is not affected by changes in salinity, density, viscosity, temperature or velocity of the components being analyzed. In addition, the high frequency signal will maintain accuracy in the presence of process coatings that would be detrimental to optical instruments.

APPLICATIONS:
- • Crude Oil and finished pipeline monitoring
- • Oil in wastewater
- • Glycol and water
- • Aqueous/organic measurement
In-line sizes: 2", 3", and 4" for 0-100% watercut ranges
DESCRIPTION
The AGAR OW-201 is a flow-through oil/water monitor spool piece designed for service in line sizes up to 4" and watercut ranges 0-100%.
Using microwave technology to measure liquid-in-liquid concentrations, the AGAR OW-201 measures hydrocarbon/water mixtures over the full range of 0-100%, regardless of which liquid is the continuous phase.
A high-temperature version of the OW-201, capable of process temperatures of 450°F (232°C), has been developed for thermal projects in Canada.
The fluid should be degassed with the sensor installed in a vertical section with ascending flow at a point where the fluids are well-mixed to ensure proper measurement.
OW-201 SYSTEM FEATURES:
- • OW-201 sensor and Data Analysis System (DAS) with microwave measurement electronics housed in the same enclosure
- • Display and serial communication which can be remotely located from the sensor up to 3000 feet
- • OW-201 sensor with flanged spool assembly that houses the microwave transmitting and receiving antennas
- • Integrally mounted measurement electronics, which are supplied in an explosion-proof enclosure, and provide the intrinsically-safe microwave signal outputs/inputs to the antennas
- • OWM/Win software and a null modem cable used to calibrate the device
- • DAS enclosure that can be mounted up to 5' from the sensor
• The DAS is also a flow computer that can provide net oil, net water and flow rates when flow meter input is supplied.
Sizes 6" and above for 0-100% watercut ranges
DESCRIPTION
The AGAR OW-202 is an insertion-type oil/water monitor designed for service in line sizes 6” and above and water cut ranges of 0-100%. This water-cut monitor measures liquid-in-liquid concentrations using microwave absorption technology.
OW-202 System Features:
- • The OW-202 system consists of an insertion-style probe, microwave measurement electronics, and a Data Analysis System (DAS) that can be remotely mounted up to 5 feet from the field sensor.
- • The OW-202 probe is an insertion-type assembly, 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 3" full-port isolation valve connected directly to the nozzle on the flow line.
- • The Agar patented "seal-housing" connects to the isolation valve. After installation, the OW-202 probe is inserted through the valve and nozzle into the flow line. The seal housing and optional insertion mechanism allows for insertion, removal, and adjustment of the probe while the line is in service and under pressure.
- • The device is calibrated with OWM/WIN software on a laptop computer and a null modem cable. The software is also used for troubleshooting, viewing reading trends, and retrieving historical data.
- • The system has a combination of explosionproof enclosures and intrinsically-safe electronics that provide microwave signal outputs/inputs to the antennas. The display and serial communication port can be located up to 3000' from the DAS. 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 is transmitted with 4-20mA signals and MODBUS.
