Results are typical for the other sensors in the 857060-xxx and 857080-> <br />regardless of length and programmability options. <br />All sensors are based on the use of a magnetostrictive sensor that is equipped with two floats. The lower float wi <br />on water. The upper float will float on fuel as well as water. <br />Results for the "water alarm" threshold will vary based upon programmed alarm levels.. <br />The "fuel alarm" is based upon a fixed threshold and is not programmable. <br />Systems containing these sensors can be programmed to alarm continuously and to shut down the dispensing sy <br />Sensor will issue an alarm if it is raised from the bottom of the containment vessel. <br />Sensors are reusable. <br />Vendor claims sensors are easily removable, cleaned, and reinstalled if an alarm is triggered or for periodic testin <br />http://www.waterboards.ca.gov/cwphomelust/leak—Prevention/lgl13/Vendor Files/veede... 11/16/2007 <br />
