OPTIONAL EQUIPMENT

INTERSTITIAL ALARM ASSEMBLY: a normally closed circuit which provides visual and audible alarms when liquid is detected in the interstitial area.

INTERFACE MODULES: Available for High and/or Low tank level outputs for alarms or pump controls. A 4-20 mA control signal is also available separate or all together.

REMOTE INDOOR MONITOR: Provides the option to monitor tanks from a remote location, both tank quantity and alarms. Ideal for offices and C stores. Powered by 120 v /12vdc plug-in power supply.

REMOTE HIGH/LOW LEVEL ALARMS: Audible and visual (LED) alarm options powered by one 9 volt battery.

CALIBRATION

Typically all Solar Gauge products are pre-calibrated by the manufacturer. The calibrations are based on the following information: shape and dimensions of the tank, actual tank capacity, type of liquid to be measured, the desired high level over fill alarm value, low level warning alarm value, and the off-set value to compensate for the unusable fuel to be left in the tank. These calibrations can also be easily accomplished by the operator in the field if necessary.

OPERATION

As liquid is added to, or removed from the tank, the changing buoyancy of the probe reflects the changing volume in the tank via the digital display. The gauge can be easily calibrated to read out in gallons, liters, pounds, inches, or % of tank full. Being solar powered, the gauge requires no external supply voltage.

INSTALLATION

The Solar Gauge needs to be installed in order to allow the gauge to receive at least one hour of direct sunlight each 24 hour period. Battery models are available if this is not practical. The Manufacturer's specifications concerning installation of the gauge, transducer and connectors, requires the connecting wire to be protected from the elements and other possible physical damages by the use of appropriate electrical items such as conduit and junction boxes. The manufacturer will not be responsible for problems arising from improper equipment installation.

ORDERING INFORMATION

Probes are custom produced depending on the tank height and type of liquid to be measured. Please supply us with the following information:

1. Tank capacity

2. Type of liquid to be measured.

3. The height of the tank

4. Total distance from the top of the 2" NPT pipe nipple to the bottom of the tank. Gauge accuracy is directly related to the accuracy of the information supplied with the order. For the best performance we recommend a minimum 6" long pipe nipple.
