Pneumercator Tank Gauging System-Spec.pdf

This document is a technical specification for a Tank Gauging/Sensing System for the Massachusetts Bay Transportation Authority (MBTA) North Cambridge Bus Facility Battery Electric Bus Modifications project, with Contract No. R53CN03. The specification details requirements for a comprehensive tank level monitoring and leak detection system for a 5,000-gallon aboveground rectangular diesel storage tank. The system must provide continuous monitoring for inventory control, interstitial liquid monitoring, supply pipe sump liquid monitoring, and supply pipe interstitial liquid monitoring. Key operational capabilities include automatic and manual leak detection tests, inventory reporting, alarm limits, report storage, and flexible console set-up using US or metric measurements.

The system requires specific technical components including a modular control console with a 10.4" SVGA color touch screen, magnetostrictive probes with five-point temperature sensing, interstitial and containment sump sensors, and accessories such as an Interstitial Sensor Interface Module and RS232/485 and Ethernet interfaces. The specification outlines precise accuracy requirements, with system accuracy to be third-party certified to United States EPA standards. Acceptable manufacturers include Veeder-Root Company and OPW, with Pneumercator identified as the primary equipment provider. The system must meet EPA regulations and provide detailed reporting capabilities, including storing at least ten delivery reports per tank in memory and generating comprehensive inventory and leak detection reports.
