About Us

The increasing concern about hydrocarbon contamination of process water and produced water has created an increasing need for in-situ, real time, and accurate low cost instrumentation that can provide rapid detection and easily usable in the field.

PetroSense sensors [1,2] represent 'best in breed' technology for the detection of total petroleum hydrocarbons (TPH). PetroSense sensors are incorporated in both a portable, field screening instrument the PHA-100 and a continuous monitoring system the CMS-4000. These sensors utilize fiber optic systems and are designed for in-situ, real time measurements of TPH and other related pollutants.

PetroSense (FCI Environmental, Inc.) has been a leader in Total Petroleum Hydrocarbon (TPH) and BTEX monitoring systems for almost twenty years. PetroSentry is the only commercially available system that can detect both the presence and concentration of TPH and BTEX in vapor and dissolved in water on a real time basis in field applications.

We offer both a portable version for on site spot testing PHA 100 Plus and a continuous monitoring version CMS 100 that allows users to monitor remote sites via the internet. The CMS 100 allow one to view all tests sites from any security enabled computer connected to the internet; this system also has the capability to send alarms via text or emails when an incident occurs. PetroSense systems have been used extensively in the by the Above Ground and Underground storage industries for leak detection, the Offshore production industry for monitoring produced water, and the industrial community for monitoring hydrocarbon intrusions in process water.

In addition, we have numerous ground water, aquifer and harbor monitors applications, designed to provide early warning alerts. And more recently, we have installed systems to monitor the impact of fracturing on the underground water sources. If you have a reason to be concerned about hydrocarbon contamination and you are looking for a proven cost effective solution, we would welcome the opportunity to visit with you about your requirements and how PetroSense fits into your solution.

PetroSense sensors operate in air (vapor), water and soil.

PetroSense sensors are non-specific detectors for TPH, semi-volatile hydrocarbons (e.g., diesel fuel, heating fuels, etc.), richloroethylene/perchloroethylene and many other related compounds. The detection capability of these sensors is unaffected by high humidity, or by naturally occurring methane. PetroSense sensors have been used in a variety of applications:

  • In-situ vapor measurements in wells
  • In-situ water measurements in wells
  • Cooling Tower monitoring
  • Water measurements in bailed samples from wells
  • Surface water measurements
  • Tracking of a hydrocarbon leak in progress (plume migration)
  • In-situ monitor for vapor extraction systems
  • Leak detection for above ground and underground storage tanks
  • Leak detection for pipelines
  • Storm water runoff monitoring
  • Sample screening for laboratory analyses
  • Site assessment
  • Groundwater remediation

Although these sensors are non-specific, there is a relative response characteristic for the different compounds that are detected. The PetroSense sensors have a very strong response for aromatic and other large hydrocarbon compounds. This makes these sensors very useful for the detection of BTEX (benzene, toluene, ethyl benzene and xylenes), which is used as a tracer for TPH leaks/contamination. The characteristic relative response factors (RRF's) can be determined for specific sites. The sensors can be calibrated for specific compounds expected at a given site, or the non-specific readings can be converted to the concentrations of these specific compounds by use of the appropriate RRF's.

PetroSense - Model PHA-100 - Portable Hydrocarbon Analyzer

The PHA-100 portable hydrocarbon analyzer is designed to meet field monitoring requirements. In the analytical mode, it gives fast and accurate quantitative data for total petroleum hydrocarbons in water and vapor. The data correlates very well with lab gas chromatographic analysis. In the screening mode, it offers fast relative data on TPH contamination, tracking field gas chromatograph data for TPH, and responds strongly to BTEX components.

PetroSense - Model CMS-1500 - Envirologger System

A key component of the CMS-1500 Envirologger system is the web logger. This small but powerful system enables almost any mixture of sensors and monitors to be connected to the system. The web logger accepts both digital and analog inputs and is pre-programmed to communicate with a wide variety of environmental monitoring instruments and sensors. Up to 255 channels of data can be collected and each channel can have a different storage and average ...
