The Inovonics TapWatch wireless submetering system is a cost effective solution, able to reduce variable utility expenses for multifamily properties. By accurately measuring individual residents’ utility consumption, and billing them directly for their use, multifamily properties can reduce net operating expenses and deliver cost effective resident amenities on a single wireless system.

Key Features:

  • Increased cash flow and operating income by eliminating variable utility costs
  • Improved net operating income
  • Increased property value
  • Improved tenant satisfaction
  • Conservation of water and other resources

How TapWatch Works

Inovonics’ TapWatch submetering system was designed for the multifamily industry. Unlike less equitable Ratio Utility Billing Systems (RUBS), TapWatch submetering uses utility meters in each unit to accurately determine each resident’s individual usage. The wireless system tracks monthly utility use, your billing company retrieves the data, and each resident receives a bill based on their actual usage. This process reduces a property’s operating expenses, and encourages utility conservation.

TapWatch-Building-OneA compatible utility meter installed in each apartment is connected to an Inovonics wireless transmitter. When scheduled the transmitter converts the meter read into a digitized signal for transmission to your repeaters.

TapWatch-Building-TwoRepeaters, which are placed at strategic locations across your site, receive and verify signals from the transmitters and amplify the signals for transmission to the receiver.

TapWatch-Building-ThreeThe remote data logger receives transmissions from the receiver and stores the data for retrieval by TapWatch software.

Pulse Meter Transmitter

The PMT provides a means for tracking and broadcasting water consumption information. The PMT connects to a compatible meter’s standard pulse or reed switched output. As the meter measures consumption, resulting pulses or switch closures are counted by the PMT, and the PMT then wirelessly transmits the data to the Remote Data Logger. The information in this radio transmission includes a unique identification number, the meter pulse count, the state of the battery, and a notice of any PMT tampering.


The repeater is an intelligent transceiver that identifies signals from Inovonics transmitters and rebroadcasts those signals. The repeater transmits at a higher power than the PMT, so the PMT radio.

RDL and Reciever

Connected to the RDL, the receiver receives radio signals from both the PMTs and repeaters. The RDL can store meter readings from up to 2,000 meters for 99 days. The billing company has the ability to contact the RDL and download the readings along with site information and any system notices at any time.

TapWatch Software

TapWatch software communicates between the RDL and the billing company. The billing company can collect, view, and monitor consumption for each individual unit, as well as update site information, and monitor the system status using the software. The usage data can be retrieved from the RDL and exported to a billing program at any time.
