D-2 Incorporated

Real Time, Precise Measurement with patented AC Sensor Technology

D-2 Inc. offers its full line of conductivity sensors with our patented AC measurment Technology. This technology allows our sensors to conduct precise conductivity and dielectric constant measurements. Our In-line (JF-1A) and handheld (JF-1A-HH) sensors are certified for the ASTM D-2624 Test Method for "The Measurement of Electrical Conductivity of Distillate Fuels." We utilize our in-line conductivity sensors to measure the fuel upstream and downstream of the injection point, to provide direct control for our additive injection systems and to certify fuel is always within specification. D-2 Inc. can provide any refinery or fuel terminal with real time conductivity control and measurement. This saves money by drastically reducing the occurances of out of spec fuel, and greatly reduces over injecting additive into the line. D-2 Inc. built systems can inject on a volume ratio basis but we also offer direct control by conductivity and volume which has been found highly accurate as it is better equipped to handle changing flow rates, and better accounts for thermal changes. Our fully automated injection systems coupled with our JF-1A sensors eliminate any problems with flow rate changes, and allows for the system to accurately inject the fuel over a large dynamic flow rate range. The JF-1A is ASTM Listed and is designed with 4-20 mA standard output to easily hook into any existing DCS system, allowing the terminal to print the average conductivity for each fuel load on the bill of lading.
