Counter vs. Turbine vs. Ultrasonic

Which water meter is right for you?

There are three industry-standard technologies for measuring flow.
Some of these technologies work better in certain applications than others.

bluebot Water Meter (ultrasonic)

The bluebot uses transit-time ultrasonic technology to measure flow, a method widely used for over 30 years. There is an upstream and a downstream transducer. The sound travels faster with the flow than against. We measure the time it takes for the sound to travel between the transducers (transit-time). Using our patented ultrasonic technology, our unit adjusts the angle of the transducers in order to measure many pipe sizes with one unit.

Water Meter Counter

A water meter counter is a non-invasive counter that utilizes your city water meter to record the meter revolutions and provide data based on that information. 

  • Inexpensive
  • Non-Invasive 
  • Long range capability

  • Only works with one type of city-provided water meter; Must locate city water box and remove heavy cover
  • Does not work with updated digital city water meters
  • Relies on city water meter for data (can produce reliability issues)
  • Not approved in some municipalities
  • Batteries need to be replaced periodically
  • Battery life depends on amount of water used, can be as little as 2 weeks for large buildings
  • Does not support multiple metering
  • Lengthy calibration process
  • Cannot share with household
  • Difficult to install

Turbine Water Meter

A turbine water meter is one that installs within a section of your water line. It utilizes a spinning turbine, volume is known for each revolution. Being installed within the pipe, they generally include a shut-off valve. 

  • Shut-off valve
  • Dedicated power

  • Variable pricing, pipe size and type dependent
  • Not compatible with all pipe sizes and types
  • Professional installation strongly recommended ($500+)
  • Permanent, invasive installation
  • Hard water can quickly seize the propeller
  • Shut-off valve can actuate inconveniently
  • Monthly subscription for data access
  • Maximum flow rate capped
  • Pressure-based flow readings, accuracy dependent on environment
  • Compatibility may require pressure reduction valve
