The Series X76LVC is designed to monitor liquid level, vapor density, pressure and hydrostatic pressure. The system generates an alarm and may shut down specific facilities if preset parameters are exceeded. The microprocessor based system provides visual and audible alarms, self-diagnostics and sensor failure indication, fail-safe shutdown and auxiliary switch outputs for communications to a facility抯 remote displays.

The liquid level sensors will indicate presence of liquids in the annular space of double-wall tanks, secondary containment pipes, manhole or caisson compartments and in-tank high level to prevent overfill. The vapor density, measured by the product抯 unique vapor transducer, is indicated on the appropriate plug-in module in parts per million (ppm) by means of a 4?digit LED display. The display not only indicates the initial background vapor density in a vadose well or the annulus of any secondarily contained vessel, but also monitors an increasing trend of vapor density. The self-contained display also provides the ability to set the alarm and shutdown setpoints without additional calibration equipment.

The pressure measurement utilized to monitor pressurized supply piping reads the pressure decay caused by a leak rate greater than 0.1 gph occurring between automatic test cycles.

A hydrostatic measurement is applied to the annulus of a double-wall tank by detecting a loss of pressure in the pressurized cavity or the loss of liquid level in a reservoir or the annulus of the tank. The X76LVC System, housed in an attractive wall mounted NEMA Type 1 Enclosure, contains the intrinsically safe barrier interface to the transducers, a number of three channel alarm modules, vapor modules, and/or dispenser modules. The front door mounted audible alarm and the flashing alarm lights are acknowledged by the ACK button and functionally tested by means of the TEST push button.
