The CMS-5000 Continuous Monitoring System is a low-cost alternative for owners/operators of aboveground  and underground storage tanks (ASTs & USTs).  It measures hydrocarbons in water or vapor interchangeably and controls 1 to 16 digital hydrocarbon probes (DHPs).  With the DHPs, the CMS-5000 is capable of detecting leaks much smaller than the EPA mandated 0.2 gal./hr.  New leaks can be detected in the presence of old contamination, and there is no response to naturally occurring hydrocarbons such as methane.

Alarm levels and how often sampling is performed can be programmed remotely. The optional alarm unit has auditory and visual alarm indicators which are activated by environmental and equipment alarms.  These alarm units can be mounted on site or remotely.  The CMS-5000 is also equipped with remote communication capabilities and can be connected via telephone, cellular and satellite to a PC.

The DHP probes have been Third Party Certified by Ken Wilcox Associates (www.kwaleak.com). Underwriters Laboratories has performed UL, CUL and KEMA ia certifications for use of the DHP in hazardous locations.  The DHP and its analog counterpart are listed in the U.S. Environmental Protection Agency (USEPA) List of Leak Detection Evaluations for Underground Storage Tank Systems (www.epa.gov/OUST/pubs/index.htm) and the State of California List of Leak Detection Equipment and Methods for Underground Storage Tanks, LG 113-12 (www.swrcb.ca.gov/cwphome/ust/lg113/lg113.htm).  The DHP has also been specified in Florida Department of Environmental Protection's Approval File No. EQ-398 and is approved as a leak detection device in areas that have been previously contaminated.

Typical applications for the CMS-5000 include leak detection at ASTs, USTs and pipelines; and monitoring of remediation sites, wastewater discharge and storm water. 

It operates for extended periods without operator attention, and features self-diagnostic software, auto zeroing and optional automatic cleaning functions. It can control up to 4 Digital Hydrocarbon Probes (DHPs) and has 0-5 Volt or 4-20 mAmp output which allows the customer to perform on-line command and control functions and have remote access to the unit for data collection when necessary.

The optional Programmable In-Line Cleaning System can be programmed to clean the probes at specified intervals between measurements.

The CMS-4000 has an optional skid mount for easy installation at remote and cramped locations. The system has no moving parts, has corrosion protected components and has NEMA-4X (explosion proof) enclosures. It comes with Class I Division 1 or 2 and Eexp II air purge options.
