The seals in your underground sumps will eventually lose integrity. Submersible turbine pump and sensor seals eventually allow trace amounts of product into the sump. Sump cover and thru-wall seals eventually let in moisture from the surface and backfill. Neither eventuality by itself poses a serious corrosion threat. But when they occur together, opportunistic microbes take advantage of the moisture and the product ethanol content to create a corrosive atmosphere which if undetected can lead to extensive damage. The Adsistor Sour Sump Sensor alerts you when microbes are metabolizing ethanol into acid in your sumps so you can repair seals before corrosion starts and spreads to the rest of the UST system.
Adsistor Sour Sump Sensors hang from any convenient location in the sump. They are read anytime sump covers are removed for sump inspections. A flashing red LED indicates when there is potential for corrosion damage. Diesel UST sensors are suspended from the refueling cap inside the delivery drop tube. The sensor is removed with the cap every time a delivery is made and can be read at that time. The hardwired version can be placed in sumps or inside the diesel UST and is read remotely at any time.

New technology that can save you the cost of replacing an STP or a UST.

In its early stages microbial induced corrosion is difficult to distinguish from harmless general uniform corrosion. What can look like a small amount of common rust now, may result in a nasty surprise at your next sump inspection. The Adsistor sour sump sensor indicates when you have a potentially serious corrosion problem so you can take action to save your STP and UST fittings from aggressive microbial induced corrosion.

Electrical resistance probe technology has always been the petroleum industry’s choice for reliable, accurate detection of sour gas & oil corrosion at production and refining facilities. But it is expensive. Adsistor Technology’s new passivated micro-particle sensor now makes ER probe technology available to the petroleum dispensing sector at an affordable price.
|
The sensor’s surface is comprised of electrically conductive ferrous particles attached to flexible anchors. A magnetic field draws the particles into light physical contact with each other to form an electrically conductive path that is easily disturbed by microbial induced corrosion on any one of the particles. This causes an increase in electrical resistance across the sensor. The particles are passivated against ordinary common corrosion from moisture. The sensor only detects the corrosion caused by the acidic metabolites of microbes, which the EPA has determined are the main cause of structural corrosion damage to UST systems.
