44 The monitoring well sensor (MWS) is a discriminating liquid sensor which detects the presence of hydrocarbons floating on groundwater. Using a float switch and innovative conductive polymer strip, the sensor identifies hydrocarbons anywhere along the length of the sensor. The MWS sensor can be used with EVO™ 550 and EVO™ 5000 fuel management system ATGs. MONITORING WELL SENSOR (MWS) SPECIFICATIONS • For use in wet monitoring wells. ORDERING INFORMATION Model Description TSP-MWS-10 10' monitoring well sensor (EVO ™ 550 and EVO ™ 5000) TSP-MWS-15 15' monitoring well sensor (EVO ™ 550 and EVO ™ 5000) TSP-MWS-20 20' monitoring well sensor (EVO ™ 550 and EVO ™ 5000) TSP-MWS-25 25' monitoring well sensor (EVO ™ 550 and EVO ™ 5000) HIGHLIGHTS • Unique alarms for the detection of hydrocarbons or decreased groundwater levels. • Completely reusable even after several exposures to hydrocarbons. • Available in four different lengths to accommodate well depth. • A microcomputer within sensor detects the presence of hydrocarbons and alerts a fuel management system of alarm conditions via digitally-encoded information. Application • Normally installed in 4" groundwater monitoring wells. • Integral well cap may be locked with standard padlock to prevent unauthorized access. Installation Note: This sensor communicates with the ATG using 3 wires. PROBES AND SENSORS
