Product Description Vapor Recovery Monitoring The Vapor Recovery Monitoring System (VRM)consists of the fol- lowing components. Vapor Recovery Monitoring Application TheVapor Recovery application uses data from the Vapor Flow Meters(VFMs)and the Vapor Pressure Sensor(VPS)to perform Po assessments on the site's vapor recovery system.VRM is an optional application on the console and may be accompanied by Fuel Management System or Secondary Containment Monitoring. Console The Console consist of either the TS-550 or TS-5000 Fuel Management Systems or the TS-EMS, Environmental Monitoring System.The console options for ISD monitoring will always include the VRM application and at least one of each of the following components. (See Figure 1) •AC Input Module • Dispenser Interface Module • Relay/10A Relay Module • Printer • Probe Module •Touchscreen •4-20mA Module Vapor Flow Meter The Vapor Flow Meter(TS-VFM)is a volume measuring meter.When a mixture of air and gasoline vapors are returned from an automobile's gasoline tank to the underground storage tank during a dispense,the vapors are measured and analyzed.The console uses these VFMs as a way to assess how well the vapor collection process is working.The VFM is used to perform the following CP-201 assessments. Assessment Type Duration EVR System Threshold Daily A/L Daily Vacuum Assist Average A/L ratio exceeds 1.90 or less than 0.33 Weekly A/L Calendar Week Vacuum Assist Average A/L ratio exceeds 1.32 or less than 0.81 There shall be one VFM per dispenser, and they wire into the Probe Module. Refer to document Vapor Flow Meter Install Guide(p/n 000-2144)for installation methods. Vapor Pressure Sensor The Vapor Pressure Sensor(TS-VPS)is a low vapor pressure transmitter.The primary purpose of the VPS is to continually measure the underground storage tank's vapor containment pressure.This vapor containment area includes the tank ullage area, and the vapor piping.The VRM continually samples the VPS and performs assessments for Over Pressurization and leakage in the vapor containment area.These assessments include: Weekly Over-pressurization Calendar Week Pressure>1.3"wcg for 5%of week Monthly Over-Pressurization Calendar Month Pressure>0.3"wcg for 25%of month Weekly Leak Test Calendar Week Pressure Leak is greater than 2x TP-201.3 There is only one VPS per ISD installation.The VPS connects to the 4-20mA Module, refer to the Vapor Pressure Sensor Install Guide(pin 000-2143).The pressure sensor shall be installed in the dispenser closest to the underground storage tanks.
