Delta C Technologies in an ISO 9001:2008 certified Canadian manufacturer of extremely
durable, high-precision watercut monitors. Our unique design approach has redefined
the field of capacitance technology resulting in straightforward, trustworthy products
with unmatched measurement performance.

While originally designed for use in conventional crude oil production and distribution
systems, our range of proven applications is continually expanding. We eagerly explore
new measurement challenges and we encourage our customers to put our technology
to the test in non-traditional ways.

Delta C has specialized in the measurement of water in oil for over twenty-five years.
We take pride in sharing our experience as we strive to enhance liquid measurement
accuracy across all industry segments.


Delta C Watercut Monitors are known for their robust mechanical and electrical design.
Unaffected by salinity variation, they offer high resolution, sensitivity and stability with
full temperature compensation and rigorous certification for use in hazardous locations.

Since 1989, Delta C Watercut Monitors have demonstrated proven reliability combined
with low maintenance requirements, user-friendly calibration and application versatility.
This has resulted in broad industry appreciation of their measurement performance and
extended service life.

Along with reduced manual sampling and decreased manpower costs, Delta C Watercut
Monitors contribute to better measurement, improved process optimization and more
cost-effective regulatory compliance.

The versatility of the Delta C Watercut Monitor is evident in the wide array of applications
our customers encounter. From refined petroleum products to high-temperature SAGD
emulsions, our technology is being deployed successfully across a variety of customer
applications including custody transfer, quality assurance and regulatory compliance.

Some of the fluids our customers work with include:

  • Diesel
  • Bio-Diesel
  • Gasoline
  • Transmission Fluid
  • Lubricants 
  • Oil-Based Coolants
  • Crude Oil
  • Natural Gas Condensate
  • Diluted Bitumen
  • Bitumen Emulsion
  • Liquefied Natural Gas (LNG)
  • Liquefied Petroleum Gas (LPG)


In basic terms, the Delta C Watercut Monitor is a highly sensitive capacitor constructed
from two coaxial electrodes which are separated by a fixed gap. As the water and oil
mixture (emulsion) flows through the gap, it acts as a dielectric (insulator) which enables
the capacitor to store a certain electrical charge. During process flow, variations in the
water/oil ratio affect the dielectric which causes the capacitance to vary. The Delta C
Watercut Monitor measures the Delta (change) in C (capacitance), hence the name of
our company.

The Delta C design brings capacitance measurement to an entirely new level of stability,
sensitivity and operating range. Our technology is so responsive it can effectively monitor
changes in water volume of 50ppm or less in many refined petroleum applications.
