TRACE® VRTTM Mobile AMR System
The TRACE® VRTTM (virtual real time), mobile AMR system, processes and stores real-time data at the gas or water meter transponder (Meter Interface Unit or MIU) for retrieval as required during a normal in-cycle read. Stored data includes 35 days of daily index readings (each in a separate electronic index [e-index]), up to four time-of-use (TOU) e-indexes and a leak-detection alarm (water). A real-time clock in the transponder allows time-based data collection.
The daily index-read-time is factory and field programmable, as is the start and stop times of each TOU e-index and the duration of the leak-detection monitoring interval and threshold level. Data is read from mobile interrogators, using two-way RF communication technology. TRACE® VRTTM transponders are addressed individually by serial number, followed by a series of commands to retrieve specific historical and time-of-use data, as well as the usual accumulated volume and alarms.
How it Works
- A. Transponders (meter interface units (MIUs)) collect, process and store virtual real time (VRT) readings at gas and water meters.
- B. Two-way radio frequency (RF) communications for the selective retrieval of transponder VRT reading by the Mobile Interrogator.
- C. Both handheld and vehicle-installed interrogators are available for the cost effective data collection of readings by large and small utilities with dense and/or scattered meter sites using radio frequency (RF) communications.
- D. Route Manager VRT, route management software, accepts and processes reading routes from the CIS, transferring the routes to interrogators as required and then retrieving read routes from interrogators for local storage and use and transfer back to the CIS.
