A totalizer is basically a counter that just counts. The Eclipse totalizer answers the
questions “how much?”, and “how fast?”. A typical application for a flow totalizer
would be a water meter for a building. As illustrated below, when a valve is opened
inside the building, water will flow through the pipe that feeds the building from the
water main. This flow causes the flowmeter to generate electrical pulses, sending it
to the totalizer.

The totalizer accumulates these pulses and displays total water usage in gallons.
The totalizer can also display flow rate in units such as gallons per minute, based
upon how fast the pulses are coming in. All flowmeters are not created equal. Even
though two flowmeters may be the same model, they probably put out a different
number of pulses per gallon. The flowmeter manufacturer is aware of this and tests
each flowmeter after it is built. The actual number of pulses that the flowmeter puts
out per gallon (or pound, or liter, etc.) is known as the K factor, and is usually stamped
