Liquid/Liquid Concentration Monitor
  Description
The AGAR OW-201 is a fl ow through oil/water monitor
spool piece designed for service in line sizes up to 4” and
water cut ranges 0-100% or 0-20%. This watercut monitor
measures liquid-in-liquid concentrations using microwave
absorption technology. Typical applications include crude oil
and fi nished product pipeline monitoring, oil in wastewater,
Glycol and water, and aqueous/ organic measurement. The
OW-201 series is the second-generation design, microwave
based liquid/liquid analyzer developed by Agar Corporation.
Agar introduced the fi rst 0-100% water cut monitor to the
market in 1985.
The high range monitor utilizes a microwave transmitter (2.45
Gigahertz) to measure bulk dielectric properties of the fl ow
stream. The AGAR OW-201 measures hydrocarbon/water
mixtures over the full range of 0-100%, regardless of the
continuous phase, or low ranges of 0-1% to 0-20% water.
Unlike other microwave, density or capacitance based
instruments; the Agar OW-201 is the only device that 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.
