Available in both single dhhliland three-phase Presentation - Version EVRInStation Diagnostics (ISD) The VST EVR Balance System uses the VeederRoot ISD systemIn-Station Diagnostics (ISD)the Veeder-Root ISD System .

6 Eliminates the cost of a separate control System . VST worked closely with Veeder-Root to incorporate all the processor monitoring and control functions. This feature is referred to as PMC or PressureManagementControlPressure Management Presentation - Version EVRInStation Diagnostics (ISD) Both ISD and PMC are simple plug-in upgrades for the existing TLS350 platformIn-Station Diagnostics (ISD)TLS-350 platform. By using this existing platform, further controls cost for EVR upgrades, Veeder-Root has approximately 85% market share, which further proves the basic For GDF s below 600,000/yr.

7 The PMC package is all that is needed for the TLS. For GDF s above 600,000/yr. the PMC/ISD package is needed for the TLS.
