Liquid -Filled RAservoir for Double -Wall Sumps With Liquid Sensor Models: WF -3 and WF -750 CONTINUOUS INTERSFITIA4 MONITORING MrTHOD (LIQUID FILLED) Certification: Certifled as a continuous, ilqurd-tilled Interstitlal space leak detertioh system for use only with Western Fiberglass, Inc., double - walled sump-, or kinder dispenser contal nment sumps. Method can be used on 1 Vs inch diameter Western Fiberglass piping manufactured November 2006 or later, Operating Principle: Hydrostatic monitoring using single4evel floc! switch, Methodology is similar to that which has been applied to liquid -filled Interstinal double-walted tanks. Propylene glycol is used to fill the interstice of Western Fiberglass' dbubir~walled sumps or under dispenser contalnment sumps. An interstitial flquid reservoir Is connected to a port at the highest point of the double -walled space. Single -level lkluid sensor model WF -3 or Wr-750 monitor the liquid In the InWrstdal reservoir and provide an alarm If thn liquid drops too low (egrxs of llquld). Alarm Conditionsi * Volume of liquid lost to aiarm depends on the amount of liquid: In the reservoir. This arriouvit is detprnlined by the operator when filling the reservoir,'rhis amount needs.to be suffleient lyd prevent false alarms from OCCurring due to the normal fluctuations in the reservoir which result from temperature and pressure variations In the sump. MIMIM M alarm volumes were obtained by fllling the reservoir to the lowest possible level to reset the alarm. While this condition provlde9'the shortest response time, it is also subject to the highest false alarm rate. Calibration: Reservoir requires no calibration Other than to insure: the upper reservoir is half full, Sensors must be calibrated and maintained in accordance with manufacturer's lnstructions. Comments, Huld reservoir Volumes and tonh'edion tightness between reservoir and sump should by Inspected annually, Liquid level in the stalnlcss steel reservoir should be visible in the sight glass.. Liquid level in the plastic reservoir should be approxlmateN ona inch above the float. switch. Western Fiberglass, Inc. 1555 Cdpperhlll Parkway Santa Rosa; CA 9s403.
