Multifamily Utility Company is a certified, fully trained TapWatch® service provider. Data is collected remotely and posted to a customized web page for download. Inovonics TapWatch® submetering system was designed specifically for the multifamily industry. Unlike Ratio Utility Billing

Systems (RUBS), submetering uses utility meters in each unit to accurately determine residents’ individual usage. The wireless system tracks daily utility use and sends the data to a billing company. The billing company then bills each resident based on their individual consumption. This process reduces a property’s operating expenses and encourages utility conservation among residents.

More than 1.2 million apartment units are currently using Inovonics submetering systems to recover utility costs. The
system is used by the largest multifamily REITS, as well as other small to large property owners, because of the numerous benefits wireless submetering delivers.

The foundation of the flexible Aclara STAR Network system is a uniquely designed meter transmission unit (MTU) that reads the utility meter. MTUs operate on a schedule specified by the utility and can transmit multiple readings per hour.
Gas and water units are mounted near or on the meter, and are powered by a permanent, lithium-ion battery that guarantees trouble-free operation for up to 20 years, depending on how often the unit communicates. Electric MTUs integrate with the meter and offer a battery backup that ensures continuous receipt of data from the meter during outages.

MTUs transfer data over secure, licensed 450- to 470-MHz radio frequencies to data collector units (DCUs) positioned strategically throughout the utility’s service area. DCUs use a variety of backhaul options to transfer data to the utility – radio and cellular signals, fiber-optics, Ethernet, and Wi-Fi. Robust system architecture ensures no missed readings and guarantees security and revenue protection.

Within the utility, the system’s network control computer (NCC) provides user-friendly access to usage data through a Web browser-based interface. Utilities can also integrate the NCC database with other applications such as billing programs or data management systems. If the STAR Network system is configured for two-way communications, the utility also can send data to the meter.
