<br />Standard bauble -Waft Tank
<br />specification'
<br />Monitoring capabilities -
<br />the following restrictions apply for
<br />the various types of double-wall tarlc
<br />monitors:
<br />a) Hydrostatic Tank Monitor -
<br />tank burial depth must not exceed 7'
<br />from tank top to finish grade.
<br />The rncnitorirg cavity must be vented
<br />to the atmosphere. The optional reser-
<br />voir sensor, supplied by Owens-
<br />Corning, is designed to automatica!ly
<br />vent the monitoring cavity.
<br />b) Liquid sensors -
<br />when cavity monitors which detec: the
<br />presence of a liquid are used, the cavity
<br />between the inner and outer tank may
<br />be either vented to the atmosphere or
<br />sealtad.
<br />c) Vacuum monitoring -
<br />when interstitial vacuum monitoring is
<br />used, the rnaxirrum vacuum is 5 psi.
<br />d) Positive air pressure
<br />monitoring --
<br />whan positive air pressure interstitial
<br />monitoring is used, the maximum air
<br />pressure is 3 psi.
<br />e) Gasoline vapor sensors --
<br />when gasoline vapor sensors are used,
<br />the cavity between the inner and outer
<br />tank may be either vented to the
<br />atmosphere or sealed.
<br />Standard Tank Notes
<br />1. Standard pipe fittings to the primary
<br />tank are 4' NPT malt couplings. All tanks
<br />include one manway with, at least,
<br />three fittings to the primary tank locat-
<br />ed in the manway cover. All other pri-
<br />mary tank fittings are mounted on the
<br />tank. Additional manways and tank fit-
<br />tings are availab!e on made -m -order
<br />tanks.
<br />2. Tank bottom deflector plates are
<br />standard under every manway and
<br />fitting.
<br />(�0n7: 009
<br />3. All double-wall tanks include a
<br />Fiberglas reservoir, used for leak mcni.
<br />coring, integrally bonded to the tank toy
<br />The reservoir includes one 4' NPT half
<br />coupling fitting (6' NPT fittings for 10
<br />diameter tanks) mounted on the top of
<br />the reservoir, allowing access to the
<br />cavity between the inner and outer tar.,
<br />walls.
<br />4. In addition to the monitoring fittinc
<br />located in the Fiberglas reservoir, tanks
<br />6,000 gallon capacity and larger'
<br />include one additional monitoring fitting
<br />(4' NPT) located at the tank top. Only
<br />the 4' monitoring fitting located at the
<br />end of the tank will accommodate liquic
<br />sensors. If a reservoir is located at the
<br />end of the tank, the fitting on the rese-•
<br />vcir will accommodate liquid sensors.
